> In products estimates are used to work out which features provide the most value, in the shortest amount of time. And this is why there is actually no difference between a product and a project. But value doesn't depend on estimates at all, as there may be many different ways to implement. Calculating value is therefore more important than estimating net value for any specific implementation - it tells you what your direction of travel should be.
