                              and

                             Commitments

Wednesday, May 16, 12
•   Good reasons to estimate:
                            • Go/no go based on cost
                            • Market window
                            • ROI comparison
                        •   Bad reasons to estimate
                            • Because . . .
                        •   Ask whether:
                            • Time, price or both?
                            • Will estimate matter?
                            • Accuracy required?
