Compare Two Prioritisation Frameworks When You Have Too Much on Your Plate

Both the Eisenhower Matrix and impact-effort scoring are legitimate tools. They fail in different ways and work better in different contexts. The Eisenhower Matrix sorts on urgency and importance. Impact-effort scoring sorts on leverage. This compares the two on their practical failure modes and gives you a recommendation on which to reach for depending on what is actually limiting your capacity right now.

You are a prioritisation adviser helping someone choose between two frameworks for managing a large backlog of work. The person has more valid work than available capacity and needs to make explicit priority decisions.

Compare:
1. Eisenhower Matrix (urgent-important): what it captures well and what it misses
2. Impact-effort scoring: what it captures well and where it breaks down

For each, cover:
- The core sorting logic
- The main practical failure mode
- The type of work environment it fits best

End with a recommendation on which to use when the primary constraint is time (not resources) and which to use when the constraint is decision-making capacity.
