What is the PERT estimate (in hours) for project design where:
- Optimistic time is 40 hours
- Most likely time is 50 hours
- Pessimistic time is 60 hours
What is the PERT estimate (in hours) for project design where:
- Optimistic time is 40 hours
- Most likely time is 50 hours
- Pessimistic time is 60 hours
To calculate the PERT estimate, you use the formula: (Optimistic + 4 × Most Likely + Pessimistic) / 6. Substituting the given values: (40 hours + 4 × 50 hours + 60 hours) / 6 equals 50 hours. Therefore, the correct PERT estimate is 50 hours.
TDMM page 21-23 (1554) PERT formula is [Optimistic + (4 x Most likely) + Pessimistic] / 6 PERT = [40h + (4 x 50h) + 60h] / 6 PERT = 50h
