Tip #8 

Don't intentionally underestimate. The penalty for underestimation is more severe than the penalty for overestimation. Address concerns about overestimation through planning and control, not by biasing your estimates.

Tip #9 

Recognize a mismatch between a project's business target and a project's estimate for what it is: valuable risk information that the project might not be successful. Take corrective action early, when it can do some good.

Tip #10 

Many businesses value predictability more than development time, cost, or flexibility. Be sure you understand what your business values the most.
