Now It’s Your Turn

1. If you use a model to predict progress on your software development project, what sort of model is it? What are the inputs? What are some significant contributors to development time that are not modeled explicitly?

2. How well does your model match the actual results you get? Is this close enough for your needs? If not, which decisions would be better with higher accuracy or precision?

3. When was the last time you calibrated your model with your actual results? What sort of changes did you make to the model?
