In team management, collaboration is preferred over dictation as it leverages the diverse strengths and insights of each team member, much like how a volleyball team utilizes each player's unique skills. This approach encourages members to contribute their expertise and ideas, leading to innovative solutions and a more engaged team. It fosters a sense of ownership and accountability, as team members feel their input is valued and significant. By collaborating, rather than dictating, a product manager can harness the collective intelligence of the team, leading to a more dynamic, creative, and effective working environment.
