Typically, you don’t find test leadership which is very technical and hands on. Having a leadership which is very tech savy, understand software architecture and to develop & test it well makes a big difference. It took a while to define this role and what are we to expect, the skills it would need.
For us test leadership was supposed to be advocates of quality across teams, architect systems which would support the quality transformation we wanted and help devise and develop practices. The ask from this role was complicated and was not an easy role to fill, but essential to make an agile transformation successful.
