Prof 2010 These four phases of lifecycle process are loosely mapped to the conceptual framework of the spiral pretence is as shown in the followers convention. - In the above figure the size of the spiral corresponds to the inactivity of the project with respect to the width and depth of the artifacts that ready been developed. - This inactiveness manifests itself in maintaining artifact consistency, turnaround testing, documentation, quality analyses, and configuration control. - development inertia may have little, or at least very straightforward, impact on changing any attach discrete component or activity. - However, the reaction time for correct to major architectural changes, major requirements changes, major planning shifts, or major organizational perturbations intelligibly increases in subsequent phases.
