Estimating always presents challenges. This is especially true when estimating the intangibles of process improvement efforts. This presentation will focus on how to reduce the guesswork associated with the estimation process by considering the following questions: What is it that you are estimating? How big is the thing you are estimating? What baselines are you using for your estimates? Should you be estimating top down, bottom up or somewhere in between? How do your estimates tie to your project plan? Do your estimates reflect ROI and business value?
