Thanks. I can't relate to Dr Herbie's pain, I've worked most my entire (admittedly short) software career in organizations that embrace FOSS tools (often by necessary, in the the internal bureaucracy for acquiring and paying for proprietary software is very difficult to navigate).
But off comment, I'd wouldn't recommend tailoring your process to the product suite. Find the best process and tailor your product suite to the process, and if it can not easily be tailored, find a new product.
Too many software teams appease the tools ideology instead of the tools appeasing them. And that's how TPS reports were born.
