No matter how careful I am, the estimated time frames for my projects are always too long. What am I doing wrong?

A. Cut each team member's estimate by 10 percent, as they have probably padded the time.

B. Never give an estimate as to how long it will take to complete a project.

C. Always plan at least one hour of overtime per employee per day.

D. Follow a checklist of suggestions to quickly see ways to reduce the schedule time.
