Any time I come across that makes me respect CMU more, I'm uncomfortably reminded of their continued association with the SEI and CMMI. Yes it came out of CMU, yes it's a cash cow, yes things like healthcare.gov show how CMMI compliance are crucial to creating quality software. Okay yeah the last thing not so much. Seriously, it's marketing snake oil and its creating wasteful barriers to entry for companies thinking…
What I would like my perspective to convey, is that the SEI is a relatively large institution. I am aware there is some methodology-type work being done, but I've never met anyone who is engaged with it.
For what it's worth, I think the SEI handles some interesting R&D. It's not all sunshine and rainbows, but in my experience it compares favorably to the startup world in terms of dynamism and engineering challenges.
[1] So, I did end up googling it, and it turns out CMMI was handed off to a dedicated institute and is no longer managed or developed by the SEI.
