UNIT-III LIFE-CYCLE PHASES
INTRODUCTION: - If there is a well delimitate separation between research and learning activities and production activities therefore the software is said to be in successful learning process. - Most of the softwares fail due to the adjacent characteristics , 1) An overemphasis on research and development. 2) An overemphasis on production. ENGINEERING AND PRODUCTION STAGES : To reach economics of scale and higher return on investment, we must(prenominal) move toward a software manufacturing process which is determined by technological improvements in process automation and component ground development. There are two stages in the software development process 1) The engineering stage: Less predictable nevertheless smaller teams doing design and production activities. This stage is decomposed into two transparent phases inception and elaboration. 2) The production stage: More predictable entirely larger teams doing anatomical structure, test, and deployment activities. This stage is also decomposed into two distinct phases construction and transition.

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