I completely get the OP's sentiment. Sonar is not some new, shiny piece of software that needs time to mature. It is literally decades in the making. If you're one of the folks that feel it gets blamed too quickly, I know why. Because it is sloppy.
Sonar is a decades old, single platform application that STILL hasn't managed to implement a smooth installation process.
Sorry ... I don't trust it. When I have a system that runs everything else perfectly fine-including previous versions of Sonar-new problems are gonna get blamed on the new version. Does this mean that the problem is always with Sonar? Hell No! Take a look at the confirmed bug list for the past 20 releases. Where do you honestly think initial su****ion should go?
A customer/user oriented company would recognize this and take responsibility instead of spending precious time playing defense. Don't waste your breath explaining why it must be something else
as your first response. Actively listen, ask questions and help your users get to the place they bought your software to help them get to.
When you just released new software that creates a new experience, where the hell do you think the fingers will point? Man up and take it. Help get to the root cause. The best defense you can possibly hope for is a solid track record. How sloppy is this again?
jeez ... simple concepts folks. You want people to see you as a shining example? Simple. Shine!
