The process script describes entry criteria interaction of the instructor and the team responsibilities of team managers and members products for the phase exit criteria A process begins with an introduction by the instructor description of the process products of the process explanation of new concepts to be applied in the process The team follows the rest of the process.

© 2002 by Carnegie Mellon University July, 2002 Lecture 5: Cyclic Development - page 5 Script Versions Some activities of a phase are unique in the first cycle, e.g., the instructor only describes the product during the launch of the first cycle. For each phase there are two versions of the associated process script, e.g., LAU1 and LAUn. The “1” script is used during the first cycle, and the “n” script is used during subsequent cycles.

© 2002 by Carnegie Mellon University July, 2002 Lecture 5: Cyclic Development - page 31 Lecture Summary Effective planning is a critical element in the success of a software project. The TSPi has a well defined structure. TSPi has three cycles; each cycle has eight phases and an associated process. The process script for each phase defines the activities for each role and the products to be produced.
