A chief executive has a span of control of 4, and every manager below also has a span of 4. There are three levels below the chief executive. How many people does the business employ in total, including the chief executive?
- Level 1 below the chief executive: 4 people.
- Level 2: 4 × 4 = 16 people. Level 3: 16 × 4 = 64 people.
- Total = 1 + 4 + 16 + 64 = 85.
Answer: 85 employees in total, with 64 at the lowest level.
