The problem with putting a list of features on the roadmap is that once it’s out, people will interpret it as a commitment. No matter how many disclaimers you attach or notes you leave, people will still have a fixed goal in mind — design or build that feature. The team will start developing and delivering the next task on the list, even when it does not solve a problem.
A product discovery is a stage when the team tackles: 1) what are the business goals? 2) what are the measurable KPI’s? 3) all the risks and problems that are to overcome, 4) and are fast at iterating the ideal and effective solution for the main business problem they have predefined.
