Where Did You Get That Estimate?
How good are our estimates? We can use PERT to estimate the time it will take to implement each requirement. We can use timeboxes to schedule the requirements within each release. If we don’t know how good our estimates are, its an exercise in futility. Scheduling is about more than predicting the future, its about knowing how much faith to have in our predictions.
