During most of my career, I've been in large Corporate organizations. There was usually room for both Managers (multiple levels) and Leaders. However, innovation from the latter rarely had any impact on the business. That was for managers to decide, and their goals almost never aligned.
Recently, I experienced the exact opposite of this dilemma. A much flatter hierarchy that's run mostly by consensus. Everyone gets a voice. Topics are debated. Actions are assigned. Politics are minimal. What an invigorating shift!!
Of course, this requires a different culture. But when it clicks, the results are amazing.
