The senior analyst on a project came up with Activity Duration Estimates as follows: Activity A: 10 days + a lag of 2 days; Activity B: 1 week + a lead of 3 days. The project manager who reviewed this, came up with some objections to these estimates. What would they most likely be?
A. The analyst should have included % variance information while mentioning the Activity Duration Estimate. This would indicate a range of possible results.
B. Activity Duration Estimates should not include any lag or lead information.
C. It is advisable not to mix up units such as days and weeks while coming up with Activity Duration Estimates.
D. The Activity Duration Estimate should have also mentioned the predecessor or successor activity to which the lag or lead is attached.
