Thus, it provides a way for gradual quality improvement over severalstages.Eachstage hasbeen carefully designedsuch that one stage enhances the capabilityalready built up. For example, it considers that trying to implement a defined process (SEI CMMlevel3)beforearepeatableprocess(SEI CMMlevel2)wouldbecounterproductiveasitbecomes difficult to follow the defined process due to schedule and budget pressures. ISO 9000certificationvs. SEI/CMM For quality appraisal of a software development organization, the characteristics of ISO 9000certificationand theSEICMM differin some respects.The differencesareas follows: ISO9000isawardedbyaninternationalstandardsbody.Therefore,ISO9000certification can be quoted by an organization in official documents, communication withexternal parties, and the tender quotations. However, SEI CMM assessment is purely forinternaluse. SEI CMM was developed specifically for software industry and therefore addresses manyissueswhich arespecificto softwareindustryalone. SEI CMM goes beyond quality assurance and prepares an organization to ultimatelyachieve Total Quality Management (TQM). In fact, ISO 9001 aims at level 3 of SEICMM model. SEI CMM model provides a list of key process areas (KPAs) on which an organization atany maturity level needs to concentrate to take it from one maturity level to the next.Thus, it provides awayforachievinggradual qualityimprovement. 137 Software Engineering Keerthana P, Manasa KN, Ganga D Bengal
