Do not make the mistake of taking on the role in your team of the greatest advocate for improving quality. Don't be quality guy.
This was the advice given to me by an ex-colleague and he assured me it was first-hand wisdom, hard-won.
My approach has been to see things as business cases. Does quality always have a business case? This is something I've been wondering about for a long time. It certainly seems to depend on the details.
Thankfully I have never had to learn this lesson first hand. I just adopted it. I remember the look in my ex-colleague's eyes.
