One to three employees (the majority of home-based businesses) • Eight to 12 employees (a very efficient company with a leader and a bunch of helpers) • 40 to 70 employees (a senior team of five to seven people, leading teams of seven to 10 — in a company where you still know everyone’s name) • 350 to 500 employees (seven leaders, with seven middle managers each, running teams of seven to 10 — actually a very efficient company) • 2,500 to 3,500 employees (more multiples of seven to 10)
