The Crack A Crack is an organizational dysfunction that feels uncomfortable. Going back to the moving example, managers had no idea how to address a Facilities issue because having cross-functional teams sitting together was a new concept for them. Sounds ridiculous to me, and maybe even to you, but they didn’t see the problem as a dysfunction. To them, it was the status quo. Each manager was responsible for their people, not for teams that included people from multiple departments.
Observe similarity with the matrix organizational structure where cross functional teams are formed as a cross section of various departments thus giving each worker two managers – project manager and department manager.
