We have studied the critical path method (in my previous blog post), which was used to develop the project schedule. This technique helped project managers manage their projects in the past.
However, in today’s fast moving era, a project manager has to build an aggressive and realistic schedule because time is important, resources are costly, and the organization may be managing many projects at the same time, requiring cross utilizing of resources.
In such scenarios in the past, project managers were having difficulties with managing schedules because of some inherent drawbacks of the critical path method.
These projects were having poor responses, such as not being able to complete on time, over budgeted, and in some cases terminated.
