I have been thinking more and more as to whether it’s a good idea to have one of the Lead QA testers as the project's Scrum Master? Here’s my thinking, which may not be the same in every company/workplace but I am sure out there somewhere in the ether there is a similar example.
Basically, our SM is a current dev team, who has his time split 70-DEV/30-SM. However, in practice, this is not the case. They seem to hide under the SM role and the DEV side suffers. I have seen this on multiple teams within our organization.
I have a thought, that as the Lead QA, they are already in a position to know what the project should be produced for the given sprint, and its acceptance criteria have clearly been defined between the Product Owner and the QA team, so test cases can be created and ready for the end of each sprint.
I feel as if we are losing a developer, while also duplicating the work/interaction with the product owners. Thoughts?
