Within the framework of a PERT network chart___________________?
Show answer Hide answer
Answer: A. all activities should be numbered
Explanation
A PERT network relies on a precise numbering system to define logical node connections. Every single activity and event node must be systematically numbered for computer processing. Correct numbering prevents logic loops and ensures accurate critical path calculations. Fulkerson rule algorithms are commonly used to number PERT network events sequentially. Initial events receive lower numbers while terminal project completion events receive higher numbers. Clear numbering allows project managers to trace dependency paths across complex schedules.
Project management software requires complete event numbering to generate reliable schedules. Unnumbered network diagrams would cause confusion and render computer analysis impossible. Standardized network conventions streamline communication among multi-firm project teams. Option B is wrong because omitting numbers on minor activities disrupts network logic. Option C is incorrect because all events must be numbered, not just the critical ones. Option D and E are invalid because numbering is mandatory for network integrity.
