• Prioritize

How to Build the Business Case

• Linear Schedule

How to Build the Business CaseDefect Estimates

456 Found

How to Build the Business Case

• Use previous project• Get total of all defects found in SIT and

beyond• Estimate 30% will be found sooner

(conservative)• Estimate 5-10 hours per defect found after
