If 20% of your people are causing 80% of the problems, how much administrative time can you expect to spend dealing with this same 20%?

• A. 20% to 30%
• B. 40% to 50%
• C. 60% to 70%
• D. 80% to 90%

Answer: (D)

Think in terms of the Pareto principle: a small group, about 20%, creates most of the problems, roughly 80% of them. If that group is driving the majority of issues, your administrative time will naturally concentrate on dealing with them—tracking, coaching, follow-ups, documentation, and remediation. Because the impact is so skewed toward that minority, you’d expect a large share of your admin work to be spent there, typically in the 80%–90% range. The other options would imply that the majority of problems come from the remaining 80%, which doesn’t fit the situation described. So the 80%–90% range best reflects where most admin time will go.
