This study focuses on cost and schedule issues of international development (ID) projects. Through empirical analysis we examine ID project cost and schedule performance and the main reasons for poor project outcome. We look at 100 projects that are sponsored by the Asian Development Bank and hosted by several Asian countries. The study identifies that most late projects experience cost underrun – an unusual cost and schedule variation relation in projects. Further we identify the root causes of project delay and cost underrun. Research findings will benefit ID project professionals, organizations and the ID project body of knowledge. The study can be extended to analyse other developing country projects sponsored by different donors.
A challenging aspect of managing the development of complex projects is the notion of design iteration or rework. Traditional project management tools such as program evaluation and review technique (PERT), critical path method (CPM), and Gantt chart allow the modelling of sequential and parallel processes in projects, but they fail to address interdependency of feedback and iteration. Design structure matrix (DSM) is a new approach to project management, used to represent, analyse dependencies among tasks and show the order in which tasks are performed. In this paper, a case of the petroleum oil field development project is demonstrated. The project duration of the petroleum oil field development project is reduced significantly by applying the DSM method.
