Building a Quality Maturity Matrix

Hi All,

I’m looking to build a Quality Maturity Matrix to help identify where our studio partners are in terms of their approach to quality within their development approach. Not to call them out/or compare them but as a constructive tool that can be used to identify where they should focus their efforts to improve. Also looking to use this as a way to identify where they feel that they need to be for particular product ambitions to help them prioritise where they focus on growing their capabilities. I’ve done some research into CMM/i, Agile, TMI etc. but wondered if anyone had any experience of building a QMM or had come across any that I could reference? Thanks in advance!
