Shikhar Sarin and Gina Colarelli O’Connor
Drawing on the path-goal theory of leadership, the present study examines the effect
of team leader characteristics on an array of conflict resolution behavior, collab-
oration, and communication patterns of cross-functional new product development
(NPD) teams. A hierarchical linear model analysis based on a survey of 246 mem-
bers from 64 NPD teams suggests that participative management style and initi-
ation of goal structure by the team leader exert the strongest influence on internal
team dynamics. Both these leadership characteristics had a positive effect on func-
tional conflict resolution, collaboration, and communication quality within the NPD
team while discouraging dysfunctional conflict resolution and formal communica-
tions. Comparatively, team leader’s consideration, initiation of process structure,
and position had a surprisingly weak effect on internal team dynamics. Further, the
findings underscore the differential effects on various dimensions of team dynamics,
the importance of controlling for project and team characteristics, and the use of
multilevel modeling for studying nested phenomena related to NPD teams. Impli-
cations of these findings are discussed.

velop their capabilities, foster interactions and learning
within the team, and champion the team’s activities

1992a; Barczak and Wilemon, 1992; McDonough and
Barczak, 1991; McDonough and Griffin, 1997; Sarin
and McDermott, 2003). Nurick Thamhain (2006) sug-
gest that effective project team leaders are social ar-
chitects who understand the interaction between
organizational and behavioral variables; suggesting
that such team leaders should be able to minimize
dysfunctional conflict and to foster a climate of active
participation.
Despite the focused attention from the academic
community, much of the past research in the NPD
literature is based largely on anecdotal data (e.g.,
Jassawalla and Sashittal, 2000), case studies (e.g.,
Hershock, Cowman, and Peters, 1994), or qualitative
data (e.g., Barczak and Wilemon, 1989; Donnellon,
1993). Although some studies (e.g., McDonough,
1993; Norrgren and Schaller, 1999) have explored
6. NPD team leadership empirically, these studies were
limited in their scope by the univariate analyses em-
ployed. Moreover, when empirical examinations were
undertaken, few studies controlled for the character-
istics of the team or the project, which could have
profound effects on how team leadership effects the
internal dynamics and performance of the NPD teams
(Ancona and Caldwell, 1992b; Griffin, 1979; Sarin and
Mahajan, 2001; Sarin and McDermott, 2003). The
NPD literature lacks a comprehensive and robust em-
pirical examination of the influence of team leadership
on the dynamics and performance of cross-functional
new product development teams. The present study
addresses this void in the NPD literature by empiri-
cally examining the effect of team leaders’ manage-
ment styles and position on an array of internal NPD
team dynamics. Such a comprehensive examination
is critical for understanding the inherent trade-offs
7. and synergies involved between various dimensions of
team dynamics.
Drawing on the path-goal theory of leadership
(e.g., Evans, 1970; House, 1971), this study focuses
on the team leader’s management style in terms of his
or her interactions with team members, style prefer-
ences for organizing work, and position and power in
the organization (Yukl, 1994). The effects of these
team leader characteristics on three broad areas of
internal team dynamics are examined: (1) conflict res-
olution behavior; (2) collaboration; and (3) commu-
nication behavior. In addition, the study controls for
key NPD team characteristics such as team size and
functional diversity and for project characteristics in-
cluding project length, complexity, and risk. Hierar-
chical linear modeling (HLM) is used to analyze the
data, which affords a number of analytical and inter-
pretive advantages over methods previously employed
8. in research on NPD teams.
Theoretical Background
Team Leader Characteristics
The team leader plays a pivotal role in setting the
work climate within the team, motivating team mem-
bers and affecting their behavior (Burke et al., 2006;
Norrgren and Schaller, 1999). Team leaders direct the
manner in which the NPD team presents itself and its
ideas to achieve personal and organizational goals
(Barczak and Wilemon, 1989; McDonough, 2000;
Sarin and McDermott, 2003).
Yukl (1994) suggests that leaders’ effectiveness is
derived from four sources: (1) the level of power and
influence possessed by the leader; (2) how the leader
interacts with others; (3) the leaders’ personal quali-
ties; and (4) the situation in which the leader is asked
to lead. Given their managerial controllability, this
research focuses on the first two sources of leader
9. effectiveness: (1) the NPD team leader’s power and
influence (as reflected by position in the organization);
and (2) interactions with the members of the NPD
team, as reflected by his or her management style

11. (Muczyk and Reimann, 1987; Sarin and McDermott,
2003). The path-goal theory of leadership (e.g., Evans,
1970; House, 1971) is used to help explain the
dynamics of these effectiveness dimensions.
The basic premise of the path-goal theory of lead-
ership is that a primary function of the leader involves
clarifying and outlining the kinds of paths and be-
haviors that will lead to goal attainment and valued
rewards (Griffin, 1979). Four distinct characteristics
or behaviors of the team leader related to his or her
management style can be identified based on this
framework (Antonioni, 1996; Burke et al., 2006;
Evans, 1970; House, 1971; Griffin, 1979; Yukl, 1994):
1. Participative leadership or participation: Participa-
tion is the degree to which the team leader invites
members’ involvement in the decision-making pro-
cess. Participative leaders consult with the mem-
bers of their teams, solicit their input, and take
12. these suggestions into account when making deci-
sions. Participation represents the way the leader
behaves toward others as well as his influence over
the team members.
2. Supportive leadership or consideration: Consider-
ation is the degree to which the team leader is
friendly and approachable and demonstrates inter-
est in the well-being of the team members. It indi-
cates his or her respect for others and conveys cues
about his or her own personal qualities. By treating
others with respect considerate team leaders create
a pleasant work environment.
3. Achievement-oriented leadership or initiation of goal
structure: Goal structuring is the degree to which
the team leader conveys to the members what out-
come or objective is expected of them. By goal
structuring team leaders set challenging goals for
the team members, expecting them to assume re-
13. sponsibility and perform to their highest level.
Through the use of such behavior team leaders
show confidence that the members of the team will
put forth the level of effort necessary to attain the
goals set for them.
4. Directive leadership or initiation of process struc-
ture: Process structuring is the degree to which the
team leader organizes and directs the activities of
team members. Process structuring by team leaders
gives specific guidance to the team members re-
garding what needs to be done and how it should
be done. The team leader schedules the work to be
done, lays out the rules and regulations to be fol-
lowed, and maintains standards of performance.
Finally, an additional source of team leaders’ effec-
tiveness identified by Yukl (1994) is considered: the
level of power/influence possessed by the leader:
5. Team leader’s position: The team leader’s position
14. is a measure of the formal as well as informal
power and influence enjoyed by the team leader
within the organization. Team leaders in high po-
sition enjoy a high stature in the organization and
are well respected for their management or techni-
cal skills. Such leaders tend to be politically savvy
and well networked within the organization. As a
result they are able to acquire needed resources, to
promote the team’s project within the organiza-
tion, and to shield the team from unwanted inter-
ference and pressures when needed.
Following Sarin and McDermott (2003), these five
team leader characteristics were considered because
they are not only managerially controllable but also
are strongly supported by established theoretical
frameworks (Evans, 1970; House, 1971; Yukl, 1994).
Internal Dynamics of NPD Teams
Healthy internal dynamics are essential for effective
15. cross-functional NPD teams and, consequently, for
the successful development of new products (e.g.,
Burke et al., 2006). Specifically, the conflict resolu-
tion behaviors (e.g., Pinto, Pinto, and Prescott, 1993;
Song, Xie, and Dyer, 2000), collaboration (e.g., Jassa-
walla and Sashittal, 1998; Pinto et al., 1993), and com-
munication behaviors (e.g., Ancona and Caldwell,
1992b; Griffin and Hauser, 1992) of cross-functional
NPD teams have been shown to have a tremendous
impact on their performance. However, the misman-
agement of these internal dynamics is among the most
often cited barriers to effective NPD team functioning
(Henke et al., 1993). In the present study three types
of internal team dynamics is considered: (1) conflict
resolution strategies; (2) collaboration; and (3) com-
munication behaviors.
Conflict resolution strategies. Individuals from
different functional backgrounds develop different
16. thought worlds and perspectives (Dougherty, 1992;
Maltz and Kohli, 1996; Sarin and McDermott, 2003).
Besides developing different worldviews, differences
can also result from variety in procedures or termi-
nology followed by each functional area, differences in
information processing techniques used, or differences
190 J PROD INNOV MANAG

in task/role ambiguity tolerated (Kolb and Rubin,
1990). These differences may create conflict, which is
inherent in all cross-functional teams (Parker, 1994;
Sarin and Mahajan, 2001). It is not the existence of
conflict, per se, but rather the mechanisms used to
resolve it that is of interest in terms of the effective
functioning of NPD teams (Amason, 1996; Pinto
et al., 1993).
17. Research on conflict management (e.g., Blake and
Mouton, 1964; Song et al., 2000; Thomas, 1977) iden-
tifies different mechanisms for resolving conflicts:
� Confronting: open discussion of the disagreement.
� Compromising: mutual bargaining amongst the
disagreeing parties; smoothing, meaning building
on the areas of agreement.
� Forcing: the coercive imposition of a solution by
an individual or a group on others.
� Withdrawal: refusal to deal with the conflict.
Cross-functional NPD teams may exhibit all of
these forms of conflict resolution to varying de-
grees.
Amason (1996) suggests that depending on how it is
resolved, conflict can either be functional (productive)
or dysfunctional (disruptive). Dysfunctional forms of
conflict resolution such as forcing or withdrawal com-
pel one disagreeing party to concede, either involun-
tarily or under duress, to eliminate further conflict.
Such a win–lose situation is ineffective and can de-
18. crease team morale, productivity, and satisfaction
(Muczyk and Reimann, 1987; Thomas, 1977). The
preferred or more functional mechanisms for resolv-
ing conflict include confronting, compromising, and
smoothing. These may enhance team operations by
bringing together the ideas of all parties and may aid
in reaching a solution that satisfies or benefits all par-
ties involved in the conflict (Kolb and Rubin, 1990;
Song et al., 2000; Thamhain and Nurick, 1994).
Collaboration. Collaboration is defined as the de-
gree to which the members of the NPD team work
together to accomplish specific tasks (Jassawalla and
Sashittal, 1998; Pinto et al., 1993). Collaboration is
indicative of effective team dynamics and an anteced-
ent to improved team performance (Ancona and
Caldwell, 1992a; Pinto et al., 1993). Although some
researchers (e.g., Thomas, 1977) consider collabora-
tion as yet another form of functional conflict reso-
19. lution strategy, others (e.g., Jassawalla and Sashittal,
1998; Pinto et al., 1993) suggest that it as a much
broader construct indicative of general integrative and
supportive interpersonal cooperation among team
members. Though some overlap is expected with func-
tional conflict resolution strategies, collaboration is
considered to be a distinct but related component of
the internal dynamics of NPD teams.
Communication. Poor communication among
team members has long been considered a detriment
to effective operation (Wilemon and Thamhain, 1983;
Henke et al., 1993), whereas effective communication
among team members has been linked to greater NPD
productivity and performance (Ancona and Caldwell,
1992b; Griffin and Hauser, 1992). Much of the focus
in the extant literature has been on the frequency of
communication between team members, with the gen-
eral consensus being that higher communication
20. frequency is positively associated with NPD perfor-
mance (e.g., Ancona and Caldwell, 1992b; Gladstein,
1984). Maltz (2000), however, notes that there is an
inherent and erroneous assumption in the NPD liter-
ature that all types of cross-functional communication
are equally important or that increased communica-
tion frequency equals good information quality.
Meanwhile, the focus on communication frequency
has resulted in other important dimensions of com-
munication remaining underexplored (Maltz, 2000;
Van de Ven and Ferry, 1980).
Although important, frequency is not the only rel-
evant aspect of NPD team communication that needs
to be considered. Team communication is a broad
concept that encompasses additional attributes. For
example, communication quality has been suggested
as a critical element in improving communication
(Bauer and Green, 1996), especially across different
21. functional areas (Maltz, 2000). Communication qual-
ity can be measured in terms of its accuracy, clarity,
detail, relevance, and timeliness (Van de Ven and
Ferry, 1980).
Similarly, information exchanges take place not
only through formally designated channels (e.g.,
meetings, memos, letters) but also through informal
mechanisms (e.g., impromptu meeting, hall talk)
(Maltz and Kohli, 1996; Van de Ven and Ferry,
1980). Maltz and Kohli (1996) suggest that although
informal communication may be more timely, formal
communication tends to be more accurate and detail
oriented. Therefore, in instances where speed and in-
novation are important, more informal channels of
communication may be desirable, whereas in other
cases where adherence to budget and schedule and
product quality are important, more formal channels

of communication might be preferable. As such, com-
munication formality may be regarded as another
appropriate indicator of team interaction and com-
munication (Kezsbom, 2000).
What is needed in the literature is an examination
of a broad set of leader characteristics on a compre-
hensive array of conflict resolution behaviors, collab-
oration, and communication behaviors of NPD teams
to gain insights that can translate to actionable pre-
scriptions for NPD managers. Particularly, the simul-
taneous consideration of a variety of internal dynamics
can help understand how the characteristics of the
NPD team leaders differentially affect various aspects
of internal team dynamics.
Conceptual Framework
23. The conceptual framework proposed in this study
is shown in Figure 1. The following section discusses
the effects of specific team leader characteristics
on the internal dynamics of cross-functional NPD
teams.
The Effect of Team Leader Participation and
Consideration on Internal Team Dynamics
Participation and consideration are perhaps the most
visible indicators of a team leader’s management style.
Participative team leaders consult their team mem-
bers, solicit their input, and involve them in the deci-
sion-making process (Antonioni, 1996; Burke et al.,
2006; Evans, 1970; House, 1971; Griffin, 1979; Yukl,
1994). Thomas (1977) suggests that the key to resolv-
ing conflicts in a group is to understand the underly-
ing power structure within the group. A participative
team leader creates an environment in which power is
dispersed more evenly among the team members.
24. Such power equity limits the ability of individuals or
subgroups to unduly dominate the conflict resolution
process in the team at the expense of others, thereby
creating a more open and productive approach to
resolving conflicts as they occur (Burke et al., 2006;
Norrgren and Schaller, 1999). Participation sets the
tone in which the leader exerts his or her influence
over the team and has been shown to be positively
related to learning within NPD teams (Sarin and
McDermott, 2003). Thus participative leadership in
NPD teams should therefore be positively related to
the use of functional conflict resolution strategies and
negatively related to the use of dysfunctional conflict
resolution strategies within the team.
Studies of high-involvement leadership suggest that
when leaders delegate decision-making authority,
team members become more actively engaged in dis-
cussions and communication among them improves
25. (Kidd and Christy, 1961; Wilemon and Thamhain,
1983). In contrast, low-involvement or autocratic
leaders discourage team members from actively
communicating and participating in team activities
(Bolman and Deal, 1993; Stewart and Manz, 1995).
When a team leader actively engages team mem-
bers in the decision-making process, members have an
opportunity to make a contribution to how a new prod-
uct development project should proceed (McDonough,
2000). As they seek to make their contributions in a
well-informed manner, the relevance and reliability of
the information exchanged increases (Kidd and
Christy, 1961; Peterson, 1997), increasing the com-
munication and cooperation within the team (Maltz,
2000). Participation by the team leader sets a more
inclusive work environment, which encourages team
members to interact with each other using informal
rather than formal channels of communication.
26. Therefore participative behavior by team leaders is
likely to be related to greater frequency and quality of
communication within NPD teams and greater team
collaboration. Greater participation is also likely to
be associated with the use of less formal channels of
communication.
Considerate team leaders demonstrate concern and
interest for the well-being of their team members.
They are friendly and approachable and treat others
with respect. In so doing, they not only convey cues
about their own personal qualities but also create a
pleasant work environment in general (Antonioni,
1996; Burke et al., 2006; Evans, 1970; House, 1971;

Griffin, 1979; Yukl, 1994). By being perceived as
approachable and empathetic, a considerate team
leader creates an environment of psychological safety
that encourages team members to openly voice dis-
28. senting opinions without fear of reprisal or backlash
(Edmondson, 1999). This allows the team members to
pursue constructive approaches to settling disagree-
ments within the team (Burke et al., 2006; Norrgren
and Schaller, 1999; McDonough, 2000). Thus team
leader consideration is expected to be positively re-
lated to collaboration and the use of functional con-
flict resolution strategies and negatively related to the
use of dysfunctional conflict resolution strategies
within NPD teams.
Additionally, due to the cultural norms set by his
or her own behavior as a model, considerate team
leaders encourage more frequent communication, fos-
ter a nurturing environment, and instill a willingness
among team members to listen to one another. As a
result, team communication tends to be more honest,
spontaneous, and unstructured (Peterson, 1997). Thus
consideration by NPD team leaders is expected to be
29. positively related to communication frequency and
quality and negatively related to the formality of in-
ternal communication.
The Effect of Initiation of Goal and Process
Structure on Internal Team Dynamics
In general, initiation of structure is conceptualized as
the degree to which supervisors assign tasks, prescribe
behaviors, and focus actions and expectations toward
process performance or goal achievement. In the
NPD context, initiation of structure is often used to
influence team member behavior and performance via
the work environment (Antonioni, 1996; Porter and
Lilly, 1996). Extant literature (e.g., Cleland, 1999;
Teas, 1981, 1983) suggests that initiation of structure
can take two distinct forms: (1) structuring that is
focused on outlining the goals and expectations of the
end result of the project (goal structuring); and (2)
structuring that is focused on outlining the activities
30. and behaviors for achieving the desired results (pro-
cess structuring).
Goal structuring is defined as the degree to which
the team leader conveys to the members what out-
come or objective is expected of them. In so doing, the
team leader sets challenging goals for the team mem-
bers and expects them to take responsibility for de-
livering on those goals (Antonioni, 1996; Burke et al.,
2006; Evans, 1970; House, 1971; Griffin, 1979; Yukl,
1994). By engaging in goal structuring, the team
leader demonstrates confidence that the members of
the team will perform to a high level and will put forth
the effort necessary for attaining the goals outlined
(Teas, 1981, 1983).
A clear exposition of expectations and expected
outcomes by the team leader helps focus the team on
a superordinate goal and helps the team members
develop a stronger sense of the team mission and
31. identity (Antonioni, 1996; McDonough, 2000; Sethi,
2000). Such goal structuring encourages team mem-
bers to share problems and to work cooperatively to-
ward the common overarching goal (McDonough,
2000), creates a learning environment within the team
(Sarin and McDermott, 2003), and encourages func-
tional conflict resolution strategies over dysfunctional
ones (Antonioni, 1996). Thus initiation of goal struc-
ture by the team leader is expected to be positively
related to collaboration and the use of functional con-
flict resolution strategies and negatively related to the
use of dysfunctional conflict resolution strategies
within the NPD team.
By explicitly stating goal expectations, team leaders
empower members to seek information related to
their own activities, to confer with others to achieve
their objectives (Bolman and Deal, 1993), and to by-
pass traditional and more formal channels of com-
32. munication, if necessary (Sarin and McDermott,
2003). Antonioni (1996) suggests that implementation
of a goal-focused structure is likely to increase pro-
ject-related communication. Therefore, initiation of
goal structure by the team leader is expected to be
positively related to the frequency and quality and
negatively related to the formality of internal com-
munication within the NPD teams.
Process structuring, on the other hand, is defined as
the degree to which the team leader organizes and di-
rects the activities of team members, by giving them
specific guidance as to what needs to be done and how
it should be done (Antonioni, 1996; Burke et al., 2006;
Evans, 1970; House, 1971; Griffin, 1979; Yukl, 1994).
Initiating of process structure involves scheduling of
the work to be done, clarifying the rules and regula-
tions to be followed, and maintaining performance
standards (Teas, 1981, 1983).
33. While process structuring ensures that the behav-
iors and activities of the team members are in sync
with project goals, it can limit opportunities for new
direction (Floyd, 1992). Excessive structuring of pro-
cesses can undermine the flexible, autonomous, and

decentralized nature of the team approach to NPD,
innovation, and creativity (McDonough, 2000; Par-
ker, 1994). However, a lack of process structure can
create ambiguity about the roles, activities, and re-
sponsibilities of team members, leading to confusion
and chaos (Wilemon and Thamhain, 1983). A lack of
structure regarding workable plans and daily activities
of the NPD team increases the potential for conflict
and dysfunctional conflict resolution (Porter and

Understanding the
Motivational Contingencies
of Team Leadership
D. Scott DeRue1, Christopher M. Barnes2,
and Frederick P. Morgeson3
Abstract
Despite increased research on team leadership, little is known
about the
conditions under which coaching versus directive forms of team
leader-
ship are more effective, or the processes through which team
leadership
styles influence team outcomes. In the present study, the
authors found that
coaching leadership was more effective than directive
leadership when the
team leader was highly charismatic and less effective than
directive leader-
ship when the team leader lacked charisma. Directive leadership
was more
effective than coaching leadership when team members were
high in
self-efficacy and less effective than coaching leadership when
36. team members
lacked self-efficacy. The moderating effects of leader charisma
and team
member self-efficacy were mediated through motivational
pathways involving
team member effort.

A growing body of research highlights how important leader
behaviors are
for team performance (DeRue, Nahrgang, Wellman, &
Humphrey, in press;
622 Small Group Research 41(5)
Druskat & Wheeler, 2003; Durham, Knight, & Locke, 1997). In
fact, Zaccaro,
Rittman, and Marks (2001) suggest that effective leadership is
one of the
more important factors in the success of organizational teams.
Yet at the same
time, we still have a limited understanding of how leaders
create and manage
effective teams (Burke et al., 2006; Kozlowski, Gully, Salas, &
Cannon-
Bowers, 1996; Zaccaro et al., 2001).
Research indicates that team leaders engage in a variety of
behaviors
aimed at facilitating team functioning and performance
(Morgeson, DeRue,
37. & Karam, 2010). One approach involves encouraging the team
to manage its
own affairs and developing the team’s capacity to function
effectively with-
out direct intervention from the team leader. First identified by
Manz and
Sims (1987), and later analyzed by many other scholars (e.g.,
Hackman &
Wageman, 2005; Morgeson, 2005; Wageman, 2001), this form
of leadership
focuses on coaching the team and empowering its self-
management. This
coaching form of leadership is particularly important given that
team leaders
are sometimes external to a team and not involved in its daily
task activities.
Using in-depth interviews and survey-based research, Manz and
Sims found
that team leaders who encourage and coach team self-
management via self-
observation, self-evaluation, and self-reinforcement were more
effective than
leaders who did not. Likewise, other researchers have found that
supportive
coaching by a team leader can lead to more effective group
processes, such as
learning and adaptation, and ultimately to higher levels of team
performance
(e.g., Edmondson, 1999; Wageman, 2001). In fact, coaching has
been estab-
lished as an important team leadership behavior in a broad array
of contexts,
including nursing (Hayes & Kalmakis, 2007), sports (Amorose
& Horn,
2000; Reinboth, Duda, & Ntoumanis, 2004), and group therapy
(Cohen,
38. Mannarino, & Knudsen, 2005).
In contrast to the coaching form of leadership, some team
leaders engage
in a more directive style by actively intervening in a team
(Morgeson, 2005).
This approach involves setting clear expectations and goals,
providing
instructions to team members, monitoring team member
performance, and
directly implementing corrective actions in the team. Research
indicates that
this more directive form of leadership can also enhance team
performance.
For example, in their study of team self-management, Manz and
Sims (1987)
also examined more directive forms of leadership and found
these directive
leader behaviors led to positive team leader evaluations.
Likewise, Pearce
and Sims (2002) showed that directive leader behaviors can lead
to higher
team performance.
In their meta-analytic summary, Burke et al. (2006) showed that
these dif-
ferent leadership styles (coaching vs. directive) can both have
positive effects
DeRue et al. 623
on team performance. But at the same time, there is an emerging
recognition
in the team leadership literature that the relative effectiveness
39. of these different
styles may depend on other factors. For example, Kozlowski,
Gully, Salas,
et al. (1996) discussed how leader behaviors interact with a
team’s stage of
development to shape team processes and performance. In their
model,
effective leaders focus on coaching team members and building
shared affect
and attitudes during early stages of team development but then
shift their
attention to applying and directing team capabilities later on.
Other scholars
have argued that the effectiveness of team leader behaviors
depends on the
nature of a team’s context (e.g., novel events that disrupt team
functioning;
Morgeson, 2005) and such team design features as task
interdependence,
team size, and resource availability (Wageman, 2001). It seems
likely that the
relationship between leader behaviors and team performance is
contingent on
a variety of factors.
Although they recognize the importance of such contingencies,
existing
models of team leadership suffer from three important
limitations. First, the
discussion of contingencies in these models is generally limited
to factors
that are external to the team’s members (e.g., task
characteristics, team size,
event types). A notable exception can be found in a recent study
by Yun,
Faraj, and Sims (2005), who showed that coaching leadership is
40. more effec-
tive for highly experienced teams, but directive leadership is
more effective
for less experienced teams. This suggests that the characteristics
of team
members can shape how they respond to coaching and directive
behaviors by
a leader. We believe that models of team leadership need to
incorporate other
team member characteristics as potential contingency factors.
A second limitation in existing models of team leadership is
that they
rarely consider characteristics of the leader and how such
characteristics can
shape the relationship between leader behaviors and team
performance. This
is an important theoretical gap because leader characteristics
likely influence
how effective team leaders are at engaging in different types of
behaviors.
For example, coaching leadership is aimed at developing team
member
capabilities and helping team members learn to work together
effectively.
Leader characteristics (e.g., charisma, social influence skills)
that enable
someone to be more effective at motivating team members to
embrace change
should thus enhance the degree to which coaching leadership
facilitates team
performance.
Finally, existing models of team leadership stop short of
identifying the
underlying mechanisms that explain any contingencies in the
41. link between
leader behavior and team performance. In their review of the
team leadership
literature, Burke et al. (2006) noted that a key “line of inquiry
[for future
624 Small Group Research 41(5)
research] concerns the identification of the underlying
mechanisms via which
leadership in teams contributes to both team performance and
performance
outcomes” (p. 302).
The purpose of our study is to address these limitations by
developing a
motivationally based contingency model of team leadership. In
our model,
the relationship between a leader’s behaviors and team
performance is con-
tingent on the leader’s charisma and the efficacy of his or her
team members.
We consider two specific behavioral approaches to team
leadership: a coach-
ing approach and a directive approach. Our focus on coaching
and directive
leadership draws on and extends prior research that
conceptualizes team
leadership along these two dimensions (Burke et al., 2006; Yun
et al., 2005).
Adopting a motivational perspective, we then theorize that
coaching and
directive leader behaviors interact with leader charisma and
team member
42. self-efficacy to differentially affect team performance. We
argue that these
contingencies operate through their effects on team member
motivation,
especially the amount of effort that team members devote to
their tasks. Thus,
not only does our theorizing identify new contingencies in team
leadership,
but it also extends current theory by offering insight into the
underlying
motivational mechanisms that explain the team performance
implications of
complex interactions among team leader behaviors, leader
characteristics,
and team member characteristics.
Coaching and Directive Forms
of Team Leadership
Behavioral perspectives on leadership have flourished since the
mid-20th
century, and so by now, there are numerous systems for
classifying leader
behaviors (see Fleishman et al., 1991 for a review). Despite the
proliferation
of these classification systems, recent reviews suggest there are
two basic
behavioral approaches to team leadership: a coaching (or
developmental),
person-focused approach and a directive, task-focused approach
(Burke
et al., 2006; Pearce et al., 2003).
Leaders engage in coaching behaviors to develop a team’s
capacity to
perform key functions. They do this by encouraging team
members to take
43. responsibility for, and work together to fulfill, such functions.
Coaching leaders
help team members (when needed) to make coordinated and
task-appropriate
use of their collective resources, and they help team members
through any
performance problems that arise (Hackman & Wageman, 2005).
Coaching
leaders refrain from actively intervening in and assuming
responsibility for
the day-to-day tasks assigned to team members. When
performance problems
DeRue et al. 625
occur, coaching leaders leverage these episodes as learning and
developmental
opportunities for team members, rather than directly intervening
in the task.
Such leaders consistently encourage team members to assume
responsibility
for their own actions and performance.
In comparison, directive leadership represents a more active and
intrusive
approach to team leadership (Pearce et al., 2003). Directive
leaders set the
team’s direction, assign goals for the team and team members,
and give team
members specific instructions about their tasks, including what
is expected of
them, how it should be done, and when it must be completed. A
directive
leader sets clear expectations for the team and then monitors
44. events to make
sure the team is performing according to plan. When team
members are not
performing well, directive leaders not only point out the
performance prob-
lems, but also direct poorly performing team members, telling
them what to
do and how to do it.
In our study, we examined the conditions under which each of
these
approaches to team leadership is most effective. Existing
research does not
sufficiently consider possible contingencies in team leadership
or the under-
lying mechanisms that explain these relationships. We theorized
that the
effectiveness of coaching versus directive leadership depends
on the charac-
teristics of both a team’s leader and those of the team’s
members. In other
words, either a coaching or a directive approach to leadership
can be effective
when employed by the right leader, in the right context. In the
next section,
we identify two important contingency factors and explain how
they can
influence team performance through their impact on the efforts
of team
members.
Contingencies in Team Leadership:
A Motivational Perspective
In our contingency model of team leadership, we posit that team
member
motivation is one mechanism through which coaching and
45. directive leadership
affect team performance. Given our interest in motivational
factors, we
focused on leader charisma as a leader attribute that can
moderate how direc-
tive and coaching team leadership influence team performance.
Charisma is
important because it is one of the key resources that leaders can
use to moti-
vate their followers (Bass, 1985; Ilies, Judge, & Wagner, 2006).
We also
focused on the moderating effects of team members’ perceptions
of self-
efficacy. Efficacy beliefs are important because they represent
an underlying
source of effort among team members that can be directed at a
team’s task
(Bandura, 1997). In this sense, leader charisma and team
member self-efficacy
626 Small Group Research 41(5)
serve as distinct contingency factors that originate from
different sources, but
may operate through a common motivational pathway. An
illustration of our
model is presented in Figure 1.
Leader Charisma
Charismatic leaders are those who “by the force of their
personal abilities are
capable of having profound and extraordinary effects on
followers” (House
& Baetz, 1979, p. 399). Charismatic leaders are often seen as
46. agents of
change who are particularly skilled at improving the
performance of followers
and seeking radical reforms in them to achieve a vision or goal
(Conger &
Kanungo, 1987). In essence, charisma is a resource that can
enable leaders
to be more effective at facilitating change by developing
followers’ beliefs
and actions in ways that ultimately produce more effective
methods for
accomplishing an objective. The potential for leader charisma to
positively
affect group outcomes has been illustrated across several
studies done in
many organizational contexts (Bass, 1990; Dvir, Eden, Avolio,
& Shamir, 2002;
Lowe, Kroeck, & Sivasubramaniam, 1996).
First, we focus on how leader charisma affects coaching
behaviors. For
coaching leaders, the primary aim is to develop team members’
individual
capabilities and their ability to work together effectively. As
Hackman and
Wageman (2005) note, coaching leaders “help members learn
new and more
effective team behaviors” (p. 270). Coaching leaders help team

align their performance behaviors with the demands of the task
environment
and seek to foster the development of team members’ skills and
knowledge
related to the team task (Hackman & Wageman, 2005;
Kozlowski, Gully,
McHugh, Salas, & Cannon-Bowers, 1996; Schwartz, 1994). So,
coaching
leaders who are charismatic should be more effective at
fostering change and
developing their teams. In contrast, coaching leaders who lack
charisma may
find it difficult to inspire team members in ways that foster
development and
encourage the team to find ways to perform its tasks better.
Whereas high
levels of charisma are an asset for coaching leaders, low levels
of charisma
are a liability.
48. We posit that charisma is an asset for coaching leaders because
charisma
affects team members’ motivation. Theories of charismatic
leadership often
emphasize motivational factors (Bass, 1985; House, 1977), and
research
suggests that charismatic leaders produce heightened levels of
activation in
followers, which lead in turn to increased levels of effort and
motivation
(Ilies et al., 2006; Shamir, Zakay, Breinin, & Popper, 1998).
In contrast to coaching leadership, directive leadership is much
less about
developing team members’ capabilities. Directive leaders
provide team mem-
bers with a clear course of action by communicating
expectations, goals, and
specific task instructions. As some have argued, in the
substitutes for leader-
ship literature (Dionne, Yammarino, Atwater & James, 2002;
Kerr & Jermier,
1978), team members with a clear course of action have less to
gain from the
inspirational actions of charismatic leaders. There is simply less
need for
leadership because the team understands its mission and the
path required
for achieving that mission. The expectations and goals set by a
directive
leader help team members to focus their efforts. Thus, whereas
a lack of
charisma can be a liability for coaching leaders, it may not be a
problem for
directive leaders.
49. Thus, we hypothesize the following:
Hypothesis 1: The relationship between team leader behaviors
and
team performance will be moderated by leader charisma such
that
(a) when leader charisma is high, coaching team leadership will
be
more effective than directive team leadership and (b) when
leader
charisma is low, directive team leadership will be more
effective
than coaching team leadership.
Hypothesis 2: The moderating effect of leader charisma on team
leader
behaviors will be mediated by team member effort.
628 Small Group Research 41(5)
Team Member Self-Efficacy
Theories of leadership in general (e.g., Hersey & Blanchard,
1982), and of
team leadership in particular (e.g., Kozlowski, Gully, Salas, et
al., 1996),
often claim that the appropriateness of leader behaviors depends
on the fol-
lowers. Of particular importance is what followers believe about
their ability
to accomplish the task at hand. These beliefs determine how
much task-
related effort followers will expend and how long that effort
will be sustained
50. in the face of challenging situations (Bandura, 1986; Dweck,
1986; Farr,
Hofmann, & Ringenbach, 1993). Moreover, team members often
have diffi-
culty focusing on team goals and developing appropriate team
strategies,
until they are sure that they can perform their own roles
effectively (Kozlowski,
Gully, Nason, & Smith, 1999). Self-efficacy embodies beliefs
relevant to
these issues. Self-efficacy is defined as “people’s judgments of
their capabili-
ties to organize and execute courses of action required to attain
designated
types of performances” (Bandura, 1986, p. 391). Individuals
who perceive
themselves as efficacious can muster sufficient effort to
produce successful
outcomes. Individuals who do not perceive themselves as
efficacious are less
likely to muster and sustain such effort. Meta-analytic evidence
supports
these claims (Stajkovic & Luthans, 1998).
We theorize that the impact of directive and coaching leadership
on team
performance will depend on the average level of team member
self-efficacy.
This is different than collective efficacy, which focuses on
beliefs shared
among team members about their team’s ability to achieve its
overall objec-
tives (DeRue, Hollenbeck, Ilgen & Feltz, 2010; Gully,
Incalcaterra, Joshi, &
Beaubien, 2002; Tasa, Taggar, & Seijts, 2007). We focus on
self-efficacy
51. because we believe that individual beliefs about personal
abilities, as opposed
to any collective beliefs about a team, will be more predictive
of team
members’ motivational reactions to team leader behaviors. This
is because
motivation and reactions to leader behaviors are individual
processes and not
the property of a team.
Directive leaders facilitate team performance by setting
expectations,
giving team members specific instructions, and then monitoring
team mem-
bers’ performance for any problems that need to be corrected.
When team
members have high self-efficacy, the directive leader’s
expectations and
task-specific instructions provide a target toward which team
members can
direct the effort and motivation that comes from feeling
efficacious.
Compared with team members with low self-efficacy, those with
high self-
efficacy are more likely to feel that they can accomplish task
objectives. As
a result, they are more likely to put forth effort and persist until
those
DeRue et al. 629
objectives are accomplished. Thus, directive leaders have a
much greater
pool of team member motivation to draw on when team member
52. self-efficacy
is high.
If team members suffer from low self-efficacy, however, then
we expect
them to respond to directive leadership negatively. Less
efficacious team
members will feel that they cannot meet the leader’s
expectations or effec-
tively carry out the leader’s instructions, and so they will be
less likely to put
forth the effort required to accomplish task objectives. In other
words, direc-
tive leaders are attempting to set expectations and give specific
instructions
to people who already have low expectations regarding task
performance,
and who lack the motivation necessary to persist when task
objectives are not
initially met. As Kozlowski, Gully, Salas, et al.’s (1996) model
of team lead-
ership suggests, it is more appropriate for leaders who have
followers with
low self-efficacy to employ a coaching approach. When
coaching their
followers, such leaders should try to develop the capacity of
team members
in ways that enhance their capacity to perform effectively. By
taking a coaching
approach, a team leader can sometimes build team members’
sense of
efficacy and reshape their expectancies regarding task
performance in ways
that increase their motivation and capacity to perform.
Thus, we hypothesize the following:
53. Hypothesis 3: The relationship between team leader behaviors
and
team performance will be moderated by team member self-
efficacy
such that (a) when team member self-efficacy is low, coaching
team
leadership will be more effective than directive team leadership
and
(b) when team member self-efficacy is high, directive team
leader-
ship will be more effective than coaching team leadership.
Hypothesis 4: The moderating effect of team member self-
efficacy on
team leader behaviors will be mediated by team member effort.
Method
Research Participants and Task
Research participants were 400 upper-level undergraduate
students enrolled
in an introductory management course at a large Midwestern
university.
Their average age was 21.8 years; 53.8% of the participants
were male. Each
student was part of a team that consisted of four regular
members and one
leader, resulting in a total of 80 teams. All individuals were
randomly
630 Small Group Research 41(5)
assigned to teams and all teams were randomly assigned to
54. experimental
conditions. In return for their participation, the students
received class credit
and were eligible for a cash prize. At the end of each
experimental session,
the top performing team based on overall team performance was
awarded
$10 per team member.
Participants engaged in a dynamic, networked, military
command-and-
control simulation. The task was a modified version of a
simulation called
Dynamic Decision Making (DDD; see Hollenbeck et al., 2002
and Moon et al.,
2004 for details) that was developed to study team behavior.
This version of
the simulation was suitable for teams with little or no military
experience. In
our study, each team engaged in two 30-minute simulation
exercises that
were the same across all teams. In each exercise, team members
were charged
with keeping unfriendly targets from moving into a restricted
geographic
space while allowing friendly targets to travel freely throughout
that space.
Each team member had four vehicles that he or she could use to
travel through
and monitor the space.
This task required a high degree of interdependence among team
mem-
bers. For instance, each member was stationed at a single
computer terminal
and could only monitor a specific portion of the geographic
55. space from that
terminal. Individually, no team member could monitor all the
targets in the
space, but collectively, the team could monitor the entire space
and all of the
targets. Furthermore, each team member had only a single type
of vehicle
(four in total), and the vehicles differed in their speed and
power. Certain
targets could only be disabled by certain types of vehicles.
Thus, team mem-
bers had to work together in order to identify the targets as
either friendly or
unfriendly and then to successfully engage all the unfriendly
targets. Together,
these features of the task ensured that team members were
interdependent,
which met the common definition of teams in the literature
(Kozlowski &
Bell, 2003).
The team leader was not positioned at a computer terminal.
Instead, he or
she was free to move around and interact with team members.
This provided
the team leader with several unique abilities. For example, the
leader was the
only person who could monitor the entire geographic space.
This allowed the
leader to monitor team members’ actions, identify opportunities
and threats
for the team, and facilitate team member coordination and
communication.
Moreover, the team leader was free to interact with team
members in ways
that were consistent with the leadership manipulation. For
56. example, if the
leader needed to coach team members, provide them with
instructions, or
implement corrective actions, then he or she was free to do so.
DeRue et al. 631
Procedure
Each team was scheduled for a 3-hour session. Roles within the
teams were
randomly assigned. The leader role was assigned first; then the
leader was
given private instructions according to the experimental
condition.
Subsequently, the team member roles were assigned.
All individuals and teams, regardless of experimental condition,
next
received (the same) training on the simulation. This training
consisted of two
separate modules. First, all participants watched a 15-minute
video that intro-
duced them to the simulation. Second, all participants were
given hands-on
instruction and time to practice all the possible tasks in the
simulation. This
second module, which lasted approximately 45 minutes, allowed
participants
to learn the basic computer mouse movements and operations
associated with
the simulation.
After their training was complete, team members completed an
57. online sur-
vey that included a self-efficacy measure. The trainer then
informed the team
of a performance-based incentive. Teams had an opportunity to
earn up to
$50 based on their overall performance in the simulation. Prior
to the first
simulation exercise, teams were given 5 minutes to discuss their
strategies for
the simulation. Most teams used the entire time exactly in this
way. The teams
then performed the first of two 30-minute simulations. Between
the first and
second simulation, the leader was instructed (privately) to lead
a team discus-
sion session and prepare the team for the next simulation using
behaviors
consistent with the leadership manipulation. Teams were given
approxi-
mately 10 minutes to discuss their performance strategies
between the simu-
lations, and again, most teams used the entire time for such
discussions.
Teams then performed the second simulation. After completing
that simula-
tion, team members and their leader completed another survey,
which
included the measure of leader charisma. Teams were then
informed of their
performance relative to other teams in the experimental session,
and the top
performing team was rewarded. To conclude the research
session, partici-
pants were thanked for their participation.
Manipulations and Measures
58. Team leader behavior. All teams were randomly assigned to one
of two
conditions. In the coaching condition, the leader was instructed
to support the
growth and development of his or her team. In the directive
condition, the
leader was instructed to set the team’s direction and goals,
establish expectations
for the team, and actively direct the actions of team members by
providing
632 Small Group Research 41(5)
explicit instructions, monitoring team performance for
opportunities to make
corrective actions, and then implementing those corrective
actions. The spe-
cific instructions given to team leaders can be found in
Appendix A.
We assessed the effectiveness of this manipulation by
measuring the
degree to which team members perceived their leader as
engaging in direc-
tive leader behaviors. Two items were used for this
manipulation check:
“When it comes to my team’s work, my team leader gave
instructions on how
to carry it out” and “My team leader set challenging and
realistic goals.”
Ratings of each item were made using a 5-point scale (1 =
strongly disagree;
5 = strongly agree). The two ratings made by each person were
59. averaged
together to produce a single index (coefficient alpha was .82,
indicating that
the index had good reliability). We expected team leaders in the
directive
condition to earn higher index scores than team leaders in the
coaching con-
dition, and that is in fact what occurred. The mean index score
for leaders in
the directive condition (M = 3.77) was significantly higher than
the mean
score for leaders in the coaching condition (M = 3.53), t(df) =
1.81(79), p <
.05, one-tailed. To see whether team members agreed in their
assessments of
the leader, we computed the intraclass correlation coefficient
(ICC) as a test
of intermember reliability. James (1982) recommends using the
ICC as a cri-
terion for aggregation, and in this case, we found support for
aggregation
(ICC
1
= .29; ICC
2
= .62; p < .01). These results provided evidence supporting
the validity of our leader behavior manipulation.
