A major operational advantage of PERT over traditional Gantt charts is that the former_________________?
Show answer Hide answer
Answer: E. inter-relationship among activities is clearly shown
Explanation
PERT networks use graphical nodes and arrows to represent complex project activity workflows. This clear network layout explicitly shows the inter-relationships and dependencies between tasks. Unlike traditional charts, PERT highlights how preceding tasks directly affect subsequent activities. Program Evaluation and Review Technique was developed for complex defense projects in the fifties. Network diagrams connect project milestones using directed arrows representing specific job durations. Logical dependencies determine the sequence in which project tasks must be executed.
Project managers rely on PERT to coordinate multi-disciplinary engineering and construction projects. Identifying inter-relationships helps teams allocate resources efficiently to avoid costly bottlenecks. Complex schedules benefit greatly from visual dependency mapping provided by network techniques. Option A is too general because Gantt charts also show activities and events clearly. Option B describes schedule data that can also be incorporated into traditional bar charts. Option D is an advantage of CPM and PERT alike, but inter-relationship mapping is broader.
