What Quality standards does ISRO follow for its space missions?

It is well known that the aerospace industry needs to follow a much higher quality standard when it comes to manufacturing components of the aircraft and space shuttles. When it comes to ISRO’s missions like MOM etc, it becomes even more important. In the aerospace industry, it is widely accepted that the manufacturing quality of indian original eqipments manufacturers are not upto the mark and simply declare them unfit for usage. Aerospace giants like UTC aerospace systems, GE, Rolls-Royce etc. try to play safe when it comes to critical parts. ISRO has been following a Zero-defect delivery programme, initiated in 2012 by its chairman. They have tried to implement it in a ground-up fashion and they have involved the technicians, the technical assistants and engineers to the top most levels. Directorate of Systems Reliability & Quality (DSRQ) acts as a nodal agency and extends technical advices and support to ISRO and helps them in maintaining the required quality standards for its mission critical components. Few standards are defined and each process has to go through them to be given a green signal. 1.      1.  Reliability management practices: Under this, they focus on reviews at different stages(conceptual to post-flight) 2.       2. Parts and material monitoring: wide range of tests is carried and the materials are stored under controlled environment. Special consideration is given to environmental impacts of materials and chemicals being used. 3.      3.  Software Quality standards are strictly followed. But what happens to the parts that have been outsourced to the vendors in the local industrial areas? ISRO, as an organization has worked to help its vendors standardize the processes. Also, the scientists from ISRO remain in constant touch with the vendors during the design development and manufacturing of the components hand share the technologies, the best practices and guide them in order to guarantee the required quality. After working for ISRO for different projects many of these SMEs have evolved in such a great way that they have turned into exporters and are being respected world-wide for their products. Thus, focusing on maintaining global quality standards, along with the need to spend less thus developing indigenous technologies and Indian SMEs as partners and consistently helping them to improve their technologies has helped ISRO maintain its quality standards.
