Projects must be delivered within cost
Projects must be delivered on time
Projects must meet the agreed scope
Projects must also meet customer quality requirements

through early and continuous delivery of
valuable software
Deliver working software frequently, from a
couple of weeks to a couple of months, with a
preference to the shorter timescale
7. Fixed Price Contracts
