Hello everyone,
I had a situation in one of my teams. The Team has 4.5 Developers and 2 QA. In the Capacity(total days worked in a Sprint), a QA is considered to do the same effort as a DEV resource for a task(User Story). The roles are different- DEV can do QA job, but QA can't do DEV job. So QA is just testing the output resulted from development.
In the Planning, when we calculate the capacity for the next Sprint, we calculate the total Man/Days for 4.5DEV + 2 QA and let's say it is 56 days per total.
