Some 5 years ago I have learned about ISO 9001 (and TickIT adaptation for software industry), CMMI, Sig Sigma and about IEEE standards. Now the situation is changed. E.g. many important firms do not extend their CMMI certifications and smaller firms drop their ISO 9001 certification. What software quality assurance frameworks and methodologies are being used today?
The Agile method is pervasive and it seems to me that all is based on experience and conventions on individual teams.
Maybe there is available some report or review about the current situation. Which framework is prospective and so best to invest my time to learn it?
