Hey Ines 😻
In my previous company we had QA sit inside of the support org. We had what we called a CSI (customer service improvement) team, essentially this team was for specialist roles that were not customer facing, so we had the likes of project, process, training, and quality specialists within the CSI team. This worked quite well for us, but I am very interested how others have it structured too!
A very simplified version of the structure was a bit like this:

In your experience, how have you seen QA be placed in other organisation charts? Has QA ever been outside of the support part of the organisation?
