One of the most useful processes I have found in product management is the introduction of UX design studios in working with clients, stakeholders, and end users. Working through user persona development and journey mapping provides an insight that enables product management to move away from traditional PRD, “waterfall” type specifications towards more user-centered design and documentation.
While it does not completely supplant the need for business analysis and user story documentation, what the design studio process does is create an instant rapport and joint ownership over the product design process with the customer.
This makes discussions between development and product management less contentious, because it is not about “PM telling development what to do” or “development deciding what gets built when” – but rather, it injects the voice of the customer into everything we do from deciding what is built, setting priorities, and getting us to the destination of a product release.
