Teams points for delivering properly produced artifacts. Artifacts in correspond modules delivered real projects. Every artifact assigned Fibonacci-like function. Manual computing values functions performed substitutes programming. Rules closely XP has two releases while each release increments. with its atmosphere competition time-compressed active lesson was successfully introduced Computer Science students at Poznan University Technology.
