Product managers should be involved in the testing process to deliver high-quality user experiences and reclaim ownership of their product. This involves understanding how testing organizations are broken down and learning about different types of tests, such as unit testing, integration testing, functional testing, accessibility testing, performance testing, and user acceptance testing. By collaborating with the development team and having a good knowledge of testing processes, product managers can ensure that their products are thoroughly tested before release, reducing the risk of re-work and delays. This, in turn, allows them to focus on creating high-quality products and user experiences, ultimately delivering value to their customers.
