If optimistic time (O) to paint is 2hr. , most likely time (M) is 3 hr...
PERT (Program Evaluation and Review Technique) is a project management tool that is used to estimate the time required to complete a task. It takes into account the optimistic time (O), most likely time (M), and pessimistic time (P) to calculate the expected time (Te) for completing the task.
Given data:
- Optimistic time (O) = 2 hours
- Most likely time (M) = 3 hours
- Pessimistic time (P) = 5 hours
Calculating the expected time (Te):
The formula to calculate the expected time (Te) using PERT is:
Te = (O + 4M + P) / 6
Substituting the given values into the formula:
Te = (2 + 4(3) + 5) / 6
Te = (2 + 12 + 5) / 6
Te = 19 / 6
Te ≈ 3.2 hours
Therefore, the approximate expected time (Te) to paint the room using PERT is 3.2 hours.
Explanation:
1. Optimistic time (O):
The optimistic time (O) is the minimum time required to complete the task. In this case, it is 2 hours. It assumes that everything will go perfectly without any delays or issues.
2. Most likely time (M):
The most likely time (M) is the time that is considered to be the most realistic estimate for completing the task. In this case, it is 3 hours. It takes into account the normal working conditions and assumes that there might be some minor delays or issues.
3. Pessimistic time (P):
The pessimistic time (P) is the maximum time required to complete the task. In this case, it is 5 hours. It considers the worst-case scenario where there might be significant delays, issues, or unforeseen circumstances.
4. Expected time (Te):
The expected time (Te) is calculated using the PERT formula. It gives a weighted average estimate of the time required to complete the task, considering all three time estimates (O, M, P). The formula takes into account the most likely time (M) more heavily than the optimistic time (O) and pessimistic time (P).
Conclusion:
Using the PERT technique, the approximate expected time (Te) to paint the room is calculated to be 3.2 hours. This estimate takes into account the best-case, most likely, and worst-case scenarios to provide a realistic expectation of the time required for the task.
