Systems development projects are time constrained. Project managers use a variety of tools to track project development, including traditional PERT/CPM charts and Gantt charts, to insure timely delivery of program code. Resource reallocation between project activities, through the identification of slack resources, is a common solution when faced with project delays or demands for earlier-than-expected delivery dates. This paper describes a network analysis methodology for reallocating resources along the critical path of a project that offers benefits not available through PERT/CPM analysis.
