Which of the following is a schedule network analysis technique that takes limited resources into account?

Question

Options

• ANetwork reserve analysis
• BCritical chain method
• CLead and lag adjustment
• DCritical path method

• A
  6% (2)
• B
  79% (27)
• C
  12% (4)
• D
  3% (1)

Explanation

Critical Chain Method (B) is specifically designed to account for resource constraints when developing a project schedule - it adjusts the schedule based on resource availability and uses "buffers" (time reserves) to protect the project completion date, making it the only option here that explicitly incorporates limited resources.

Why the distractors are wrong:

• A. Network reserve analysis - not a real, standard schedule network analysis technique; this is a fabricated distractor.
• C. Lead and lag adjustment - a technique for fine-tuning dependency relationships between activities (e.g., start an activity early or delay it), but it doesn't consider resource limitations.
• D. Critical path method (CPM) - identifies the longest sequence of dependent tasks to determine the minimum project duration, but assumes unlimited resources; it does not account for resource constraints.

Memory tip: Think "chain" = links in a chain can only hold as much as the weakest link (your most constrained resource). Critical Chain = resource constraints. If the question mentions resources, go with Critical Chain over Critical Path.
