Everybody who hires in the software industry complains about how hard it is to find good QA people. It’s no wonder, considering how little we respect them and how little we pay them.
Testers are power users on the inside of your team, but nobody listens to them because nobody respects them.
Make the QA lead the equal of the Design and Dev Leads in your hierarchy. Give the QA Lead line management over the QA team. It is weirdly commonplace for the QA team, including the QA Lead, to be line managed by the Dev Lead.
