When estimating an ICT distribution designer project timeline schedule based on the scope of work which two scheduling methods use network diagrams to integrate logical activities and identify…

Question

Options

• AIf This Then That (IFTT)
• BGantt Chart
• CWork Breakdown Structure (WBS)
• DCritical Path Method (CPM)
• EProgram Evaluation Review Technique (PERT)

• A
  5% (1)
• B
  70% (14)
• C
  20% (4)
• E
  5% (1)

Explanation

There appears to be an error in the provided answer key. Based on the question's criteria - network diagrams + critical path identification - the correct answers are D and E, not B and D.

Why D (CPM) and E (PERT) are correct: Both Critical Path Method and Program Evaluation Review Technique use network diagrams (nodes and arrows representing task dependencies) to map activity sequences and identify the critical path - the longest chain of dependent tasks that determines the minimum project duration. These are the two classic network-based scheduling techniques in project management.

Why the distractors are wrong:

• A (IFTTT): An automation web tool ("If This Then That") - completely unrelated to project scheduling.
• B (Gantt Chart): Uses a horizontal bar chart to display task timelines, not a network diagram. It cannot inherently show dependencies or calculate critical paths without additional tools.
• C (WBS): A hierarchical decomposition of project deliverables/scope - it organizes what needs to be done, but contains no network diagram or scheduling logic.

Memory tip: Think "Network = CPM + PERT" - the two methods that draw networks of activity arrows. Gantt is a bar chart (bars, not networks). If your exam source marks B and D as correct, flag it - this appears to be a typo where E was swapped for B.
