... my testing expertise became less valuable at the end of the cycle and much more valuable at the start.

The more effort I put into testing the product conceptually at the start of the process, the less I effort I had to put into manually testing the product at the end because less bugs would emerge as a result.

I’ve had a lot of discussions this year around the role of the tester. Let’s put that aside from now and start thinking about the role of a software developer.
A software developer needs to be able build a product with confidence that it does what it’s expected to do.
Knowing how to do that at a basic level should be critical to the role of a good software developer.
For that reason, we need more testing in software development. And it needs to be done by the people building the product.

Forget developers in test, we need testers in development (2013)
