This is why you MUST throw away the prototype. Ditching bad code is much easier when there’s less of it. Throwing away the first iteration takes discipline and must be executed cold and ruthlessly. It is not enough to admit the code needs rewriting. You must be prepared to delete code from day 1. 3 months is a good life cycle for a functional prototype. Budget for 1 month of overhaul for the first 3 months of development and 1 month of overhaul for every 1 month of development beyond that.
