What is constraint migration personal systems?

Example: You spent three weeks fixing your decision-making bottleneck. You built a decision journal, pre-committed to weekly priorities every Sunday night, and reduced your average decision latency from 3.2 days to 0.8 days. Throughput surged — for about ten days. Then it plateaued. You are deciding faster than ever, but now your task list is full of decided, ready-to-execute items that you cannot get through fast enough. Work-in-progress balloons. Deadlines stack. You feel the same frustration you felt before, but in a different location. The constraint has moved. Decision-making is no longer the bottleneck — execution capacity is. You need fewer concurrent projects, deeper focus blocks, or delegation, none of which your decision-speed optimization addresses. The old solution is irrelevant to the new problem.

This concept is part of Bottleneck Analysis in the How to Think curriculum.
