Consider Integration: Talk to the people who build the products that integrate with your product.  Learn how to operate their product and perform integration tests that are otherwise being automated via mocks. You just can’t beat the real thing.

Faster Feedback –   Everybody wants faster feedback.  Humans can deliver faster feedback than automation engineers on new testing.  Machines are faster on old testing (e.g., regression testing).  Report back on what works and doesn’t while the automation engineer is still writing new test code.   WebsiteBooklet
