Concept in brief.
While it’s tempting to hire the most senior team you can, an effective product team needs junior talent. By mentoring junior talent, you leverage your senior product managers and increase their product skills by broadening their exposure to problems.
When you hire product managers, avoid hiring for a prototypical PM and minimize hiring to solve a current need. Hiring specialists as standard practice leads to reduce adaptability as products change. Build an adaptable product team by hiring individuals who add complementary or supplementary strengths and perspectives to your product team.
