Complexity Theory in Construction Project Time Management
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 6, Issue 5
Abstract
Within the past two decades, management of construction projects is dramatically faced with the uses of different methods and techniques from multiple disciplines. This is mainly due to the rapid changes in project types and contracts, increased level of complicated expectations among stakeholders, and unprecedented factors. As a result, construction projects are increasingly encountering with schedule delays, increased costs and risks, poor quality and increased number of claims and litigations. As such, project managers' main concern is to complete project on time and within budget in such complex and chaotic environment. To this end, they mostly focus on dealing with operational and practical factors influencing complexity rather than analyzing the factors that surround the project environment and have greater impact on understanding the complexity of projects. This research aims at introducing complex environment of construction projects and shed light on better understanding the factors that cause project time management become a complex task. In order to achieve this objective, complex and chaotic environment in project management is investigated from difference perspectives: structural, social, dynamic, and uncertainties. Afterwards, project time management elaborated in PMBOK standard (Project Management Body Of Knowledge) is used to systematically identify inherent parameters of complexity and chaos. Finally, practical suggestions are provided for project managers and schedulers on how to consider and incorporate complexity-based parameters to other feasible factors in their project scheduling and controlling so that better project time management can be achieved. This research contributes significantly to the provision of managerial tools that have the potential benefit of supporting construction projects by better estimating project duration, as a crucial process in project management system. More effective estimation of activities duration by involving factors derived by complex and chaotic project environment can reduce risks and uncertainties and save enormous amounts of cost and time in construction projects.
