A dynamic model for adjusting contemporary construction projects behaviors in today changeable environments

Project management knowledge has been used in many project oriented organizations in last two decades across the world. despite, rate of project success did not change during these years. we believe there is a basic challenge in projects environment for managing them based on its inherent characteristics. in fact, project management knowledge use theories and concepts that are belong to process management world, as a different world. there is no enough attention to project characteristics as a fundamental differentiation for coping projects. identification of construction projects nature in order to discern variables that create the project behaviors is main concern of the paper.considering project characteristics in this research revealed construction project nature creates from combination two aspects. first, detecting environmental changes to develop a need and second prepare resources structure to respond the need. important management challenge in this model is environmental continuous changes that alter the need and exchange resources structure. so, the paper considers how these aspects can be operationalized for developing a dynamic project management model. it gives some ideas about why project complexity might be considered to be increasing, and how construction projects move towards shorter timescales. the effectiveness of the model is verified by applying it for predicting some construction projects behavior. the results of the paper may capable future project managers to test any decision before its applying and lead to a new project management tool for construction projects management.
