Stakeholders, users, customers—even the development team—all have competing needs and compelling reasons why their proposed solutions should be the highest priority. When product owners try to take all of these needs into account at one time, they end up with a bloated backlog of must-do features and no way to decide which to do first. The resulting product, if the team can cobble one together, is likely to be a mixed-up mess rather than a targeted, purposeful release.
