You’ve just hired a superstar. This person is overqualified for the job, yet they accept the position gladly.
And then, after a short while, you realize your productivity goes down. Why?
More than specialists on specific processes and generalists’ geniuses, focus on what will make the whole team perform as clockwork: the 4 Cs.
Hire and train staff capable of good
Communication, in every direction.
Collaboration, in their department.
Cross-functionality (with other departments).
Culture (Your business culture, that is).
You do this, productivity will improve.
