Abstract
A large body of researches has demonstrated that cultural values directly influence the success of organizational strategies and
managerial actions. On the same way, the successful use of Lean Manufacturing (LM) practices requires more than the use of
tools. Although many manufacturing facilities worldwide use LM practices, dimensions of nation’s culture and leadership may
moderate the expected results from the LM implementation. Using LM background and cultural data, this paper presents the
results of an exploratory study on the moderation of Lean Leadership effectiveness by dimensions of national cultural values. The
study was based on the feedback from the practice of Lean Leadership in various multinationals based in Morocco. A
questionnaire was elaborated, validated, and sent to overall 120 respondents holding various management and operational
positions in many multinational companies. The results of this study are used to identify directions for proposing an adapting
model of operations management to the Moroccan SMEs.
Keywords: Survey, Lean Manufacturing, Lean Leadership, National culture, Organizational culture, Multinational,

1. INTRODUCTION
LM is more a philosophy than just a toolbox; it is a fully
integrated management and manufacturing philosophy and
approach [2]. However, it also made clear, that the tools are
important, but the basic tenet of LM is that lean culture and
Lean Leadership are the most important factors.
Additionally, the strong balance among technological
efficiency and leadership effectiveness has been largely
considered as the limit that separates success and failure of
LM implementation projects [22], [40], [38], [11], [17], [8],
[44]. Taking into account that cost pressure seems to force
organizations to relocate work into low cost countries, like
Morocco, an investigation of LM perceptions, risk factors
on the lean pathway proves very important. In absence of
studies and research in Morocco related to LM, there is no
clear evidence of the level of success and problems/barriers
in the LM implementation in those organizations. Some
problems/ barriers that might cause company to stumble
may root of the leadership of management [36] and the
specific national culture who can indirectly influences
leadership behaviors differently to LM requirements [19].
Because the national cultures are quite diverse, and the ways
of practicing leadership seem to be subject to the influence
of the social and cultural environment in which they are
used, the resulting organizations and the work systems are
equally diverse [41].
Thus, the purpose of this study is to explore the status of
Lean Leadership maturity in multinational facilities based in
Morocco. Especially, the status aims to discover the
perception of managers toward the LM in terms of
understanding of the concepts, the assumption of Lean
Leadership roles, and to confirm the hypothesis of a role of
national culture in nurturing the lean culture and its
influence on the Lean Leadership maturity.
The following section reviews the literature and related
theory to LM, Lean Leadership, and the cultural impact.
Next we describe the data, sample, and measures. We then
discuss the results. Finally we point out the contributions to
both the academic and more to the practitioner literature.
2. LITERATURE REVIEW
2.1 Lean Manufacturing and Lean Leadership
Lean Manufacturing (LM) is often regarded as the most
important strategy for manufacturing firms desiring to
achieve world-class performance [24]. LM is a collective
term for production practices aimed at increasing value
creation and reducing waste in all forms. LM refers to an
integrated social-technical system whose main objective is
to eliminate waste by concurrently reducing or minimizing
supplier, customer, and internal variability [47]. Therefore,
the main objective of LM is to achieve maximum efficiency,
carrying out operations at a minimum cost and with zero
waste [40].

However, any transfer of organization or management
techniques is also a transfer of leadership profile and
organizational culture [39]. Although manufacturing
facilities worldwide use LM practices, dimensions of
leadership and nation’s culture my moderate LM results
[33]. According to [35], LM programs fail because
managers have confused lean solutions for the process that
led to what we see in a Toyota factory and specific Lean
Leadership that daily involved employees in these
processes. [17] introduced the Lean Leadership as a
methodical system for the sustainable implementation and
continuous improvement of the LM. Lean Leadership is a
continuous process that involves making followers want to
contribute to continuous improvement and process
excellence. This includes the customer orientation,
proximity management, as the long-term development of
employees. To be able to transform the entire organization
into a lean organization, the Lean Leadership must be,
assimilated, understood, and modeled across all
management levels.
2.2 Lean Manufacturing Practices, National and
Organizational Culture
Managers are encouraged to implement LM practices
globally because of its universal effectiveness. However, as
a successful implementation of any continuous improvement
demarche can only be achieved if the employees believe in
the change that is about to happen, the implementation
process of the LM needs to be adjusted to specific external
and internal characteristics of each organization [3]. So, for
the expected performance of the LM, several behavioral
adjustments and managerial interventions may be necessary
in each LM adoption. This implies that the form and use of
such LM practices as waste reduction, 5S, and just-in-time,
may be guided by the underlying cultural values of
managers and workers in a facility [48].
Given that countries vary in their cultural values [30],
incongruence between national culture and lean culture may
corrupt the practice of LM and moderate expected
performance improvements [33]. In his research on the
moderation of LM effectiveness by dimensions of national
culture, and by analyzing data from more than 1400
facilities in 24 countries, [33] confirms that LM is more
effective in a future-oriented (FO), performance-oriented
(PO), and assertive national culture (AS). Likewise, [25], in
his analyze of the cultural lean inhibitor impact breakdown,
suggests that the cultural barriers affect all the five aspects
of LM (The Value, Value stream, Continuous Flow,
Customer Pull, and Perfection). Therefore, when there is no
tension between national and lean culture, LM practices are
easier to implement and hence will have higher
performance. In contrast, divergence between national and
lean culture could make implementing LM problematic.
Nevertheless, in the GLOBE study about leadership
effectiveness and culture, [19] argue that national culture
does NOT predict leadership behavior or organizational
culture included lean culture. Too, [44], in his study of 189
manufacturing plants between Eastern (Japan and south
Korea) and Western (Germany, United States, Finland, and
Sweden) countries, indicates that organizational culture has
more an effect on manufacturing performance than national
culture, and in result, a weak influence of national level
factors on manufacturing performance. Likewise, [7], in his
research about the role of organizational culture in LM,
sustains that a specific organization culture profile
characterizes all successful lean plants; Thus plants,
compared to unsuccessful lean plants, show an
organizational culture marked by more institutional
collectivism (IC), a strong future orientation (FO), and a big
human orientation (HO). Yet, [4] and [41], argument that
the “culture of work” matters more than national culture in
the degree to which manufacturing practices can be applied
across countries. In an era of globalization, these results
have practical implications for national organizations and
organizations expanding across national boundaries by
developing an internal organizational culture consistent with
LM requirements whatever the culture of the country of
relocation
3. RESEARCH AND DATA ANALYSIS
3.1 Sample Selection and Analysis Approach
The empirical research took place end of 2014. The data was
captured through meticulous survey questionnaires
undertaken in various multinationals based in Morocco
whose production processes related to automotive and
aeronautic manufacturing. Although the companies targeted
were international, staff will predominantly be Moroccan,
enhancing our ability to identify national cultural influences
on our findings. The survey questionnaire items were
developed based on LM background, Lean Leadership
fundamentals, and cultural data. The survey questionnaire
was split into the following categories with several or more
questions in each category to determine:
- the perception about the LM,
- the critical practices of Lean Leadership,
- behavioral effects of Lean Leadership on the shop floor,

In total, 41 questionnaires have been returned, of which two
had to be discarded because of insufficient data, yielding 39
usable questionnaires (34% response rate). Table.1 provides
an overview of the responses by sector, by multinational
origin, by function, and by hierarchical level of respondents.
The majority of the respondents to the survey were
managers (53%) and supervisors (31%). Two hierarchical
positions enhancing our ability to identify critical Lean
Leadership behaviors. Finally, 50% of factories are French,
25% Japanese, 17% German, and 8% American.

First we analyzed the LM perception as a result of the
understanding of LM philosophy using descriptive statistic.
The questions were created on basis of various literature
studies [50], [34], [22], [43], [30], [2], [45], [32]. Table.2
shows respondent views about LM perception.
Unfortunately, an important conclusion was the reduction of
lean concepts in a toolbox to reduce lead time (78.26%) and
improve operations (60.87%), not in a fully integrated
management and manufacturing philosophy (21.74%)
focused on customer satisfaction (21.74%) trough the
organization and management of product development,
operations, suppliers and customer relations (26.09%).
Another interesting aspect is that only 17.39% seed the LM
as a way to create new work and business; a significantly
lower result than founded among our European neighbors
evaluated at 42% [2]. As previously outlined, looking at the
fact that through reducing the ultimate goal of lean to
reducing the lead time it has to be said that quit a
remarkable managers does not yet fully see the chances and
potential of LM implementation [3]. Thus, unless managers
in the company ignore about the potential of LM,
improvement initiatives are less likely to be initiated and the
miraculous gains in performance through LM are less likely
to be reached.
Next, as mentioned earlier, we tried to understand, and
predict the impact of specific national cultural values on
Lean Leadership and LM practices and the effectiveness of
these practices. Eight questions were formulated on the basis
of the Lean Leadership literature review [50], [34], [35],
[45], [16], [17], [40], [11], [38] to investigate about the
critical Lean leadership practices in national culture and
leadership values context. The results are summarized in
Table.3.

The findings about difficulty average number indicate that
managers moderately assumed the quality of product, and
moderately encouraged the shop floor employees to stop the
line in any case of quality deviation with the same difficulty
average number (47.83%). Thus result provides other
finding about the large difficulty for supervisors to put
quality above productivity and efficiency (52.66 %). Also,
the results indicate that managers and supervisors are less
performing in motivating and supervising, training, and
facilitating the work in the shop floor with a difficulty
average number of 57.49%. This study indicates also an
average difficulty of 55.56% for managers and supervisors
to encourage and participate with employees in both process
and performance indicators improvement projects.
Unfortunately, research among successful organizations
indicates that results are better if performance managements
is focused on supporting improvement rather than just for
monitoring and control the shop floor. Changes in the role
and behavior of top and middle management by less
information flow stagnation, transparency, direct contact
with the shop floor, and continuous management support to
workers are considered the cornerstone of successful LM
implementation. Likewise, as [22] note, management
practices, such as employee involvement in continuous
improvement programs, employee integration in problem-
solving teams, and employee training, are acknowledged to
form core components of a LM program. Such as Lean
Leadership literature advocates that management should
function as a facilitator rather than supervisor [44],
managers have to support the continuous improvement
culture by living it and setting an example [17].
In the last, we analyzed the influence of Lean Leadership
practices on the shop floor behavior. The results are
presented in Table.4, which show, for each lean requirement
in the shop floor employee behavior the average number of
difficulty.

Decidedly, it can be observed that behavioral on the shop
floor are largely influenced by specific Lean Leadership
practices. The findings about difficulty average number
indicate that the shop floor operators are moderately less
focusing on improvement (50.72%) and problem solving
(48.79%). Equally, the results revealed that the shop floor
operators are moderately less inciting to stop lines in case of
quality problem (52.66%). These results can be considered a
revealing consequence of large difficulty for managers to
put quality above productivity and efficiency (52.66%)
depicted in Table.3. The finding is totally agreed with
operations management researches also believe that Lean
Leadership has implications for employee outcomes [27].
Likewise, these results provide various researches
examining the link between management behavior and LM
performance and clearly assume that leadership affect
behavior of individuals in the shop floor, which in a positive
case facilitates the achievement of LM promises regarding
organizational benefits and customer satisfaction.
Consequently, it is the integration of LM practices in the
shop floor through a perfect Lean Leadership that would
have the ability to achieve multiple organizational goals and
superior result in quality of product and service [12].

4. CONCLUSION
The objective of this study was to close a gap in Lean
Manufacturing research in Morocco by analyzing the
moderation of Lean Leadership effectiveness by dimensions
of national cultural by exploring the status of Lean
Leadership practices in various multinationals located in the
country. To summarize it can be concluded that the survey
findings fit with existing theory. As shown in Table.3,
managers and supervisors are less focused in continuous
improvement projects and less performing in training the
shop floor employees. These results provide a deeper
understanding of why major organizations find
implementing and using Lean Manufacturing practices
difficult. The explanation for this finding is that Lean
Manufacturing and quality approaches require a
fundamentally different philosophy of management than the
traditional mass production approach.
Next, we have investigated the relation between Lean
Leadership practices and each of these behavioral effects, as
depicted in Table.4. This table confirms the broad impact of
leadership on the shop floor behavior. It is also a further
confirmation of various researches who argued that the
success of Lean Manufacturing depends heavily on the
topmost leaders embracing it, believing in it, and properly
applying it. Consequently, no lean behaviors will be
sustained unless they are modeled. Thus, managers must
model the lean behavior they desire if they expect it from
their shop floor employees.

  • 1. IJRET: International Journal of Research in Engineering and Technology eISSN: 2319-1163 | pISSN: 2321-7308 _______________________________________________________________________________________ Volume: 04 Issue: 02 | Feb-2015, Available @ http://www.ijret.org 542 NATIONAL CULTURE IMPACT ON LEAN LEADERSHIP AND LEAN MANUFACTURING MATURITY - CASE STUDY OF MULTINATIONALS BASED IN MOROCCO Youssef Larteb1 , Abdellah Haddout2 , Mariam Benhadou3 1 PHD Student, Team rheology and industrial plastics processing, ENSEM, Casablanca, Morocco 2 Professor, Team rheology and industrial plastics processing, ENSEM, Casablanca, Morocco 3 Professor, Team rheology and industrial plastics processing, ENSEM, Casablanca, Morocco Abstract A large body of researches has demonstrated that cultural values directly influence the success of organizational strategies and managerial actions. On the same way, the successful use of Lean Manufacturing (LM) practices requires more than the use of tools. Although many manufacturing facilities worldwide use LM practices, dimensions of nation’s culture and leadership may moderate the expected results from the LM implementation. Using LM background and cultural data, this paper presents the results of an exploratory study on the moderation of Lean Leadership effectiveness by dimensions of national cultural values. The study was based on the feedback from the practice of Lean Leadership in various multinationals based in Morocco. A questionnaire was elaborated, validated, and sent to overall 120 respondents holding various management and operational positions in many multinational companies. The results of this study are used to identify directions for proposing an adapting model of operations management to the Moroccan SMEs. Keywords: Survey, Lean Manufacturing, Lean Leadership, National culture, Organizational culture, Multinational, Morocco. --------------------------------------------------------------------***---------------------------------------------------------------------- 1. INTRODUCTION LM is more a philosophy than just a toolbox; it is a fully integrated management and manufacturing philosophy and approach [2]. However, it also made clear, that the tools are important, but the basic tenet of LM is that lean culture and Lean Leadership are the most important factors. Additionally, the strong balance among technological efficiency and leadership effectiveness has been largely considered as the limit that separates success and failure of LM implementation projects [22], [40], [38], [11], [17], [8], [44]. Taking into account that cost pressure seems to force organizations to relocate work into low cost countries, like Morocco, an investigation of LM perceptions, risk factors on the lean pathway proves very important. In absence of studies and research in Morocco related to LM, there is no clear evidence of the level of success and problems/barriers in the LM implementation in those organizations. Some problems/ barriers that might cause company to stumble may root of the leadership of management [36] and the specific national culture who can indirectly influences leadership behaviors differently to LM requirements [19]. Because the national cultures are quite diverse, and the ways of practicing leadership seem to be subject to the influence of the social and cultural environment in which they are used, the resulting organizations and the work systems are equally diverse [41]. Thus, the purpose of this study is to explore the status of Lean Leadership maturity in multinational facilities based in Morocco. Especially, the status aims to discover the perception of managers toward the LM in terms of understanding of the concepts, the assumption of Lean Leadership roles, and to confirm the hypothesis of a role of national culture in nurturing the lean culture and its influence on the Lean Leadership maturity. The following section reviews the literature and related theory to LM, Lean Leadership, and the cultural impact. Next we describe the data, sample, and measures. We then discuss the results. Finally we point out the contributions to both the academic and more to the practitioner literature. 2. LITERATURE REVIEW 2.1 Lean Manufacturing and Lean Leadership Lean Manufacturing (LM) is often regarded as the most important strategy for manufacturing firms desiring to achieve world-class performance [24]. LM is a collective term for production practices aimed at increasing value creation and reducing waste in all forms. LM refers to an integrated social-technical system whose main objective is to eliminate waste by concurrently reducing or minimizing supplier, customer, and internal variability [47]. Therefore, the main objective of LM is to achieve maximum efficiency, carrying out operations at a minimum cost and with zero waste [40].
  • 2. IJRET: International Journal of Research in Engineering and Technology eISSN: 2319-1163 | pISSN: 2321-7308 _______________________________________________________________________________________ Volume: 04 Issue: 02 | Feb-2015, Available @ http://www.ijret.org 543 However, any transfer of organization or management techniques is also a transfer of leadership profile and organizational culture [39]. Although manufacturing facilities worldwide use LM practices, dimensions of leadership and nation’s culture my moderate LM results [33]. According to [35], LM programs fail because managers have confused lean solutions for the process that led to what we see in a Toyota factory and specific Lean Leadership that daily involved employees in these processes. [17] introduced the Lean Leadership as a methodical system for the sustainable implementation and continuous improvement of the LM. Lean Leadership is a continuous process that involves making followers want to contribute to continuous improvement and process excellence. This includes the customer orientation, proximity management, as the long-term development of employees. To be able to transform the entire organization into a lean organization, the Lean Leadership must be, assimilated, understood, and modeled across all management levels. 2.2 Lean Manufacturing Practices, National and Organizational Culture Managers are encouraged to implement LM practices globally because of its universal effectiveness. However, as a successful implementation of any continuous improvement demarche can only be achieved if the employees believe in the change that is about to happen, the implementation process of the LM needs to be adjusted to specific external and internal characteristics of each organization [3]. So, for the expected performance of the LM, several behavioral adjustments and managerial interventions may be necessary in each LM adoption. This implies that the form and use of such LM practices as waste reduction, 5S, and just-in-time, may be guided by the underlying cultural values of managers and workers in a facility [48]. Given that countries vary in their cultural values [30], incongruence between national culture and lean culture may corrupt the practice of LM and moderate expected performance improvements [33]. In his research on the moderation of LM effectiveness by dimensions of national culture, and by analyzing data from more than 1400 facilities in 24 countries, [33] confirms that LM is more effective in a future-oriented (FO), performance-oriented (PO), and assertive national culture (AS). Likewise, [25], in his analyze of the cultural lean inhibitor impact breakdown, suggests that the cultural barriers affect all the five aspects of LM (The Value, Value stream, Continuous Flow, Customer Pull, and Perfection). Therefore, when there is no tension between national and lean culture, LM practices are easier to implement and hence will have higher performance. In contrast, divergence between national and lean culture could make implementing LM problematic. Nevertheless, in the GLOBE study about leadership effectiveness and culture, [19] argue that national culture does NOT predict leadership behavior or organizational culture included lean culture. Too, [44], in his study of 189 manufacturing plants between Eastern (Japan and south Korea) and Western (Germany, United States, Finland, and Sweden) countries, indicates that organizational culture has more an effect on manufacturing performance than national culture, and in result, a weak influence of national level factors on manufacturing performance. Likewise, [7], in his research about the role of organizational culture in LM, sustains that a specific organization culture profile characterizes all successful lean plants; Thus plants, compared to unsuccessful lean plants, show an organizational culture marked by more institutional collectivism (IC), a strong future orientation (FO), and a big human orientation (HO). Yet, [4] and [41], argument that the “culture of work” matters more than national culture in the degree to which manufacturing practices can be applied across countries. In an era of globalization, these results have practical implications for national organizations and organizations expanding across national boundaries by developing an internal organizational culture consistent with LM requirements whatever the culture of the country of relocation 3. RESEARCH AND DATA ANALYSIS 3.1 Sample Selection and Analysis Approach The empirical research took place end of 2014. The data was captured through meticulous survey questionnaires undertaken in various multinationals based in Morocco whose production processes related to automotive and aeronautic manufacturing. Although the companies targeted were international, staff will predominantly be Moroccan, enhancing our ability to identify national cultural influences on our findings. The survey questionnaire items were developed based on LM background, Lean Leadership fundamentals, and cultural data. The survey questionnaire was split into the following categories with several or more questions in each category to determine: - the perception about the LM, - the critical practices of Lean Leadership, - behavioral effects of Lean Leadership on the shop floor, 3.2 Data Analysis & Results Table -1: Sample characteristics Industrial sectors in sample Subdivision % of total Multinational origin French 50 Japan 25 Germany 17 USA 8 Industry sector Automotive 50 Aeronautic 42 Others 8 Function Corporate 16 Methods & Process 32 Quality 22 Production 25

Table.1 provides an overview of the responses by sector, by multinational origin, by function, and by hierarchical level of respondents. The majority of the respondents to the survey were managers (53%) and supervisors (31%). Two hierarchical positions enhancing our ability to identify critical Lean Leadership behaviors. Finally, 50% of factories are French, 25% Japanese, 17% German, and 8% American. Table - 2: Questionnaires responses regards the lean perception Lean perceptions % Away to create new work and business 17.39 A fully integrated management philosophy 21.74 A philosophy that absolutely focuses on customer value (customer first focus) 21.74 A system for organizing and managing product development, operations, suppliers, and customer relations 26.09 A method to reduce headcount 39.13 A system to make products with fewer defects in order to strive for perfection 39.13 A system to reorganize the firm by product family and value stream 47.83 The use of teamwork and continuous improvement 52.17 A toolbox of techniques (just-in time &. automation) to improve manufacturing and operations 60.87 The consequent elimination of non value adding tasks in order to reduce lead time 78.26 First we analyzed the LM perception as a result of the understanding of LM philosophy using descriptive statistic. The questions were created on basis of various literature studies [50], [34], [22], [43], [30], [2], [45], [32]. Table.2 shows respondent views about LM perception. Unfortunately, an important conclusion was the reduction of lean concepts in a toolbox to reduce lead time (78.26%) and improve operations (60.87%), not in a fully integrated management and manufacturing philosophy (21.74%) focused on customer satisfaction (21.74%) trough the organization and management of product development, operations, suppliers and customer relations (26.09%). Another interesting aspect is that only 17.39% seed the LM as a way to create new work and business; a significantly lower result than founded among our European neighbors evaluated at 42% [2]. As previously outlined, looking at the fact that through reducing the ultimate goal of lean to reducing the lead time it has to be said that quit a remarkable managers does not yet fully see the chances and potential of LM implementation [3]. Thus, unless managers in the company ignore about the potential of LM, improvement initiatives are less likely to be initiated and the miraculous gains in performance through LM are less likely to be reached. Next, as mentioned earlier, we tried to understand, and predict the impact of specific national cultural values on Lean Leadership and LM practices and the effectiveness of these practices. Eight questions were formulated on the basis of the Lean Leadership literature review [50], [34], [35], [45], [16], [17], [40], [11], [38] to investigate about the critical Lean leadership practices in national culture and leadership values context. The results are summarized in Table.3.

Thus result provides other finding about the large difficulty for supervisors to put quality above productivity and efficiency (52.66 %). Also, the results indicate that managers and supervisors are less performing in motivating and supervising, training, and facilitating the work in the shop floor with a difficulty average number of 57.49%. This study indicates also an average difficulty of 55.56% for managers and supervisors to encourage and participate with employees in both process and performance indicators improvement projects. Unfortunately, research among successful organizations indicates that results are better if performance managements is focused on supporting improvement rather than just for monitoring and control the shop floor. Changes in the role and behavior of top and middle management by less information flow stagnation, transparency, direct contact with the shop floor, and continuous management support to workers are considered the cornerstone of successful LM implementation. Likewise, as [22] note, management practices, such as employee involvement in continuous improvement programs, employee integration in problem- solving teams, and employee training, are acknowledged to form core components of a LM program. Such as Lean Leadership literature advocates that management should function as a facilitator rather than supervisor [44], managers have to support the continuous improvement culture by living it and setting an example [17]. In the last, we analyzed the influence of Lean Leadership practices on the shop floor behavior. The results are presented in Table.4, which show, for each lean requirement in the shop floor employee behavior the average number of difficulty. Table- 4: Questionnaires responses regards the behavioral effects of the Lean Leadership practices on the shop floor Difficulty average Difficulty scale (%) Lean requirements in the shop floor employee behavior % notatall& hardlydifficult Moderately difficult largely& entirelydifficult In case of quality problem, operators insist to stop lines and production machinery (Andon system) 52.66 13.04 60.87 26.09 Operators are actively involved in both standards and processes improvement projects 50.72 8.70 78.26 13.04 Operators maintain and respect workplace standards and warn of any damage or deviation 50.72 13.04 69.57 17.39 Operators participate and are actively involved in problem- solving process 48.79 8.70 82.61 8.70 Operators respect instructions and quality specifications 42.03 17.39 73.91 8.70 Decidedly, it can be observed that behavioral on the shop floor are largely influenced by specific Lean Leadership practices. The findings about difficulty average number indicate that the shop floor operators are moderately less focusing on improvement (50.72%) and problem solving (48.79%). Equally, the results revealed that the shop floor operators are moderately less inciting to stop lines in case of quality problem (52.66%). These results can be considered a revealing consequence of large difficulty for managers to put quality above productivity and efficiency (52.66%) depicted in Table.3. The finding is totally agreed with operations management researches also believe that Lean Leadership has implications for employee outcomes [27]. Likewise, these results provide various researches examining the link between management behavior and LM performance and clearly assume that leadership affect behavior of individuals in the shop floor, which in a positive case facilitates the achievement of LM promises regarding organizational benefits and customer satisfaction. Consequently, it is the integration of LM practices in the shop floor through a perfect Lean Leadership that would have the ability to achieve multiple organizational goals and superior result in quality of product and service [12].

CONCLUSION The objective of this study was to close a gap in Lean Manufacturing research in Morocco by analyzing the moderation of Lean Leadership effectiveness by dimensions of national cultural by exploring the status of Lean Leadership practices in various multinationals located in the country. To summarize it can be concluded that the survey findings fit with existing theory. As shown in Table.3, managers and supervisors are less focused in continuous improvement projects and less performing in training the shop floor employees. These results provide a deeper understanding of why major organizations find implementing and using Lean Manufacturing practices difficult. The explanation for this finding is that Lean Manufacturing and quality approaches require a fundamentally different philosophy of management than the traditional mass production approach. Next, we have investigated the relation between Lean Leadership practices and each of these behavioral effects, as depicted in Table.4. This table confirms the broad impact of leadership on the shop floor behavior. It is also a further confirmation of various researches who argued that the success of Lean Manufacturing depends heavily on the topmost leaders embracing it, believing in it, and properly applying it. Consequently, no lean behaviors will be sustained unless they are modeled. Thus, managers must model the lean behavior they desire if they expect it from their shop floor employees. REFERENCES [1].
