standard iso 9001 2000 is the quality assurance standard that applies to software engineering
ISO 9001:2000 replaced all three former standards of 1994 issue, ISO 9001, ISO 9002 and ISO 9003. Design and development procedures were required only if a company does in fact engage in the creation of new products. The 2000 version sought to make a radical change in thinking by actually placing front and centre the concept of process management (the monitoring and optimisation of a company's tasks and activities, instead of just inspection of the final product). The 2000 version also demanded involvement by upper executives in order to integrate quality into the business system and avoid delegation of quality functions to junior administrators. Another goal was to improve effectiveness via process performance metrics: numerical measurement of the effectiveness of tasks and activities. Expectations of continual process improvement and tracking customer satisfaction were made explicit.
