Incontrast, software development is a creative process and individual skills and experienceareimportant. ISO 9000 does not automatically lead to continuous process improvement, i.e. does notautomaticallylead to TQM. SEICAPABILITYMATURITY MODEL SEI Capability Maturity Model (SEI CMM) helped organizations to improve the quality of thesoftware they developandthereforeadoptionof SEI CMMmodelhassignificantbusinessbenefits. SEICMMcanbeusedtwoways:capabilityevaluationandsoftwareprocessassessment.Capability evaluation and software process assessment differ in motivation, objective, and thefinal use of the result. Capability evaluation provides a way to assess the software processcapability of an organization. The results of capability evaluation indicates the likely contractorperformance if the contractor is awarded a work. Therefore, the results of software processcapability assessment can be used to select a contractor. On the other hand, software processassessment is used by an organization with the objective to improve its process capability. Thus,thistypeof assessment is forpurelyinternal use. SEI CMM classifies software development industries into the following five maturity levels. Thedifferent levels of SEI CMM have been designed so that it is easy for an organization to slowlybuildits qualitysystem starting from scratch. Level 1: Initial - A software development organization at this level is characterized by ad hocactivities.Veryfewornoprocessesaredefinedandfollowed.Sincesoftwareproductionprocessesare notdefined,differentengineersfollowtheirownprocessandasaresultdevelopment efforts become chaotic. Therefore, it is also called chaotic level. The success ofprojects depends on individual efforts and heroics. When engineers leave, the successors havegreat difficulty in understanding the process followed and the work completed. Since formalproject management practices are not followed, under time pressure short cuts are tried outleadingto low quality. 134 Software Engineering Keerthana P, Manasa KN, Ganga D Bengal
