Questions and Answers

What is the purpose of Critical Path Method (CPM) and Program Evaluation and Review Technique (PERT) in project management?

  • To calculate the overhead costs of each activity
  • To determine the crash time of each job
  • To increase the resources for all activities evenly
  • To identify critical and non-critical jobs in a project (correct)

    • In project schedules, what characterizes a non-critical job?

  • It has the minimum time required for completion
  • It starts at node 1
  • It has float or slack within the allowable time frame (correct)
  • Its earliest starting time equals its latest completion time

    • What does the term 'crash time' refer to in project management?

  • The maximum time a job can be accomplished in
  • The time taken to increase the resources for a job
  • The minimum time a job can be accomplished in (correct)
  • The time at which a job faces an increase in cost
