What enables us to determine the earliest and the latest times for each of the events and activities and thereby helps in the identification of the critical path?

Programme Evaluation and Review Technique (PERT) enables us to determine the earliest and the latest times for each of the events and activities and thereby helps in the identification of the critical path. Program evaluation is a systematic method for collecting, analyzing, and using information to answer questions about projects, policies and programs, particularly about their effectiveness and efficiency. Review Technique or PERT is used to identify the time it takes to finish a particular task or activity.
