DEVELOPMENT OF PROJECT EXECUTION COMPLEXITY INDEX
Ebtisam Mirza1, Nadeem Ehsan1
ABSTRACT
Growing complexity is one of the main reasons behind failure of many projects. Project management academicians
have conceived a few complexity characterization models but a comprehensive complexity measurement model
encompassing factors of important project constraints i.e. scope, time and cost is still missing. In this research, a
model has been developed to compute PECI (Project Execution Complexity Index) for various categories of projects
considering varying levels of complexity, i.e. PECI(R) for R&D/Technology projects, PECI(I) for Infrastructure development
projects and PECI(O) for Other projects. A complexity scale starting from 0 = least complex to 10=highly
complex has also been proposed in order to rank and compare the projects. This ranking will help the decision makers
to decide which projects to include in their portfolio and which projects to give priority while assigning resources
more efficiently. Moreover, project managers will be able to manage their projects better, by first comparing them in
order of complexity, followed by tweaking the factors which contribute towards enhancing their complexities.
