Final answer:
The correct answer is option 4, which correctly pairs PERT with non-repetitive jobs, optimistic time with the shortest time activity can be completed, CPM with repetitive jobs, and pessimistic time with the longest time for an activity.
Step-by-step explanation:
The student is asking to match project management concepts from List I with their descriptions from List II. The correct matches are:
- a. PERT (Program Evaluation and Review Technique) with i. Used for non-repetitive jobs.
- b. Optimistic time with iii. The shortest possible time to complete the activity if all goes well.
- c. CPM (Critical Path Method) with ii. Used for repetitive jobs.
- d. Pessimistic time with iv. The longest time that an activity takes.
Therefore, the correct answer is (4) a-i, b-iii, c-ii, d-iv.
PERT is a planning and control tool used for managing complex and non-repetitive projects, while CPM is used for projects involving activities that are repetitive in nature. Optimistic time refers to the minimum time required to complete a task, assuming everything goes according to plan without any interruptions. Conversely, pessimistic time is the maximum time required to complete a task, considering potential obstacles and delays.
