The seeds of major software disasters are usually sown in the first three months of commencing the software project. Hasty scheduling, irrational commitments, unprofessional estimating techniques & carelessness of the project management function are the factors that tend to introduce terminal problems. Once a project blindly lurches forward toward an impossible delivery date, the rest of the disaster will occur almost inevitably. T. Capers Jones
5. When schedule slippage is recognized, the natural tendency (& traditional) response it to add more manpower. Like dousing a fire with gasoline, this makes matters worse, much worse. More fire requires more gasoline & thus begins a regenerative cycle which ends in disaster.
Brooks Law: “ Adding manpower to a late software project makes it later.”
