Sources of Complexity
Bob Prieto
Chairman & CEO
Strategic Program Management LLC
We have seen, scale and complexity become mutually reinforcing in large programs.
New sources of complexity emerge that are not typically encountered in traditional scale
projects. Even our traditional focus on metrics fails us when it comes to complexity.
How much complexity does a project have? Does it change over time? What are the
principle drivers of complexity? How does complexity in one project compare to
another? How does complexity in one project execution approach compare to another?
The questions continue but our management of complexity in large scale programs
remains challenged. New challenges require new solutions but these have not come
fast enough in the world of large projects.
The table below highlights some sources of complexity in large engineering and
construction programs. Much must be done if we are to improve the performance of
these large scale projects.
2
Sources of Complexity in Large Engineering &
Construction Programs
Strategic Business
Outcomes(SBO)
Organizational
 Ambiguity; visibility; lack of
alignment
 SBO migration over time
 Conflicting SBOs
 Competitive landscape changes
 Market migration
 Economic susceptibility (local;
global)
 Owner complexity (JV; alliance;
state owned enterprise)
 Scope/reach of defined
outcomes
 Shared understanding of
program management
inadequate
 Clarity of roles and
responsibilities inadequate
 Resistance to change
 Value destroying processes and
procedures
3
Sources of Complexity in Large Engineering &
Construction Programs
Political
 Lack of sense of urgency
 Stress level; team fatigue
 Silos that impact communication
and knowledge sharing
 Cultural issues
 Number of locations
 Distance of program from day-
to-day business
 Workshare systems and
process experience and
effectiveness inadequate
 Duplication of efforts
(Owner/PMC)
 Duplication of efforts
(PMC/suppliers)
 Risk aversion vs. risk
management
 Degree of political sensitivity
(project or key supply locations)
 Political stability (number of
relevant political players;
number of election cycles or
other anticipated changes of
government)
4
Sources of Complexity in Large Engineering &
Construction Programs
Project Portfolio
Program Execution
 Role in power struggles
 Sustainability of political will
 Role of supply chain in
international relations (enabler
or held hostage)
 Extent of capacity building and
feedback role
 Number of projects
 Precedences and
interdependencies
 Uncertainties of assumptions
and data
 Sophistication of modeling and
analysis
 Assumption migration
 Definition of “white space”
 Number of constraints
 Cyclomatic complexity
 Structural complexity of
program plan, WBS, and
schedule
 Degree of shared constraints
(first; second; third order)
 Degree of constraint coupling
5
Sources of Complexity in Large Engineering &
Construction Programs
(direct and indirect)
 Number of changes
 Supply chain resiliency; extent
of common failure modes
(common sub-tier sourcing)
 Depth of labor pool (total and
critical skills)
 Labor predictability (labor
action; productivity)
 Physical complexity of projects
comprising the program
(footprint; degree of temporary
construction; duration of
discrete work activities (duration
of transition phases))
 Specialized equipment
availability and lead times
 Permitting and regulatory
complexity; timeliness
 Logistical congestion and
chokepoints
 Flexibility of sequencing
 Financial and financing
constraints
 Regulatory constraints
6
Sources of Complexity in Large Engineering &
Construction Programs
Technological
Environmental
 Management tools and systems
not adequately integrated
 Shallow risk management
 Extent of feedback mechanisms
 Distance of projects and key
supply locations from day-today
operations
 New process
 New tools
 Technical design basis not fixed
 Prototyping, planning, and
analysis inadequate
 Specialized materials or skills
 Limited number of suppliers
 IT complexity
 Systems integration extent
 Extent of regulatory processes
 Number of significant issues
 Effective footprint
 Duration of impacts
7
I am sure I could continue to add to this list, but the essential point is that large projects
are different and the approach to their management must similarly be different. The
challenges and opportunities are different. Scaling matters, most importantly, because
of the hidden dimensions that it allows to unfold.
For a fresh look at how the management of large projects must change read The
Theory of Management of Large Complex Projects. http://www.lulu.com/shop/bob-
