What is Project Replanning?
Project Replanning is a process for planning an existing project again in the same or some altered way. It entails repetition of the whole planning process or its parts to resolve execution failures of the prior plan and then develop a new, more improved plan which is called a re-plan. Sometimes, project replanning means reuse of current plan to solve a new problem while focusing on initial goals and utilizing the same resources available.
Correctness is the primary goal of the replanning process. For example, when a problem is revealed within an existing project plan yet no solution is found to fix the problem, the project manager needs to reuse or re-plan the project in order to correct the current plan and create scenarios for addressing the problem. Such scenarios will be necessary corrections required for turning the plan into a new efficient re-plan.
Quality is the second goal of the replanning process. Back to our example: when the manager works on developing corrective scenarios and re-plans the project, he/she needs to be sure that quality of the new re-plan becomes higher or at least remains the same as compared to quality of the original plan. Otherwise, the replanning process becomes pointless, and even if the problem is fixed with the re-plan the initial goals get under a higher risk of failure because of reduced quality.
