Prof 2010 UNIT-III LIFE-CYCLE PHASES INTRODUCTION: - If there is a well particularise separation between research and acquisition activities and production activities hence the software is said to be in successful learning plow. - Most of the softwares fail due to the close characteristics , 1) An overemphasis on research and development. 2) An overemphasis on production. ENGINEERING AND PRODUCTION STAGES : To tense economics of scale and higher return on investment, we must(prenominal) attain toward a software manufacturing process which is determined by proficient improvements in process automation and component ground development. in that respect are two stages in the software development process 1) The engineering stage: Less predictable nevertheless littler teams doing design and production activities. This stage is decomposed into two transparent phases rise and elaboration. 2) The production stage: More predictable ent irely bigger teams doing anatomical structure, test, and deployment activities. This stage is also decomposed into two distinct phases formula and transition. www.jntuworld.com www.jntuworld.com D.SAMEERA, Asst.

Prof 2010 These four phases of lifecycle process are loosely mapped to the abstract framework of the spiral model is as shown in the followers figure. - In the above figure the size of the spiral corresponds to the inertia of the project with respect to the breadth and depth of the artifacts that have been developed. - This inertia manifests itself in maintaining artifact consistency, regression t esting, documentation, quality analyses, and! configuration control. - increase inertia may have little, or at to the lowest degree very straightforward, impact on changing any habituated discrete component or activity. - However, the reaction time for adapt to major architectural changes, major requirements changes, major planning shifts, or major organizational perturbations clearly increases in subsequent phases.
