01 / THE SHIFT

PARETO PRINCIPLE

THE OLD 80/20 RULE

80% of results
come from 20%
of effort.

The Pareto Principle taught leaders to find the vital few—the small number of inputs that drive most outcomes.

DERMER RULE

THE NEW 80/20 RULE

80% of work should be AI. 20% must be human.

AI is not merely a tool for routine tasks. It can analyze, create, predict, personalize, optimize, coordinate and execute. The advantage comes from redesigning every function around its full capability—and elevating people into the work humans must own.

02 / THE DISTINCTION

NOT 80% OF PEOPLE.

80% OF THE WORK.

The Dermer Rule is not a headcount formula. It is a work-design formula. Let AI bring intelligence, creation, speed, precision and scale to the full operating system. Concentrate human effort where judgment, context, coordination, trust, empathy, taste, ethics, courage, vision and accountability change the outcome.

04 / PUT IT TO WORK

DON’T ASK,
“HOW CAN AI HELP?”

Ask: “Why is a human still doing this?”

  1. List the work.Break every function into its recurring decisions, actions and outputs.
  2. Design the AI 80%.Give AI responsibility for analysis, creation, prediction, personalization, optimization, orchestration and execution.
  3. Define the human 20%.Name the moments that demand judgment, context, coordination, trust, empathy, taste, ethics, courage, vision or accountability.
