## Short Definition

Decision Rights Matrix is a decision tool for turning decision speed with accountability into a concrete decision authority map.

## 一言でいうと

Decision Rights Matrix is a decision tool for turning decision speed with accountability into a concrete decision authority map.

## 意味

Decision Rights Matrix defines the working structure used when recurring decisions stall because authority, escalation, and veto boundaries are unclear. In Decision Rights Matrix, the important work is not the template itself; the page states the decision boundary, required evidence, owner, and review cadence. Used well, Decision Rights Matrix turns vague discussion into an auditable management choice and exposes trade-offs before resources are committed.

## 役立つ場面

Decision Rights Matrix changes decisions by making decision speed with accountability visible before commitments are made. It helps leaders decide whether to start, stop, resize, or resequence work based on evidence rather than meeting momentum. It reduces rework because assumptions, owners, and review points are explicit enough to challenge.

- Decision Rights Matrix changes decisions by making decision speed with accountability visible before commitments are made.
- It helps leaders decide whether to start, stop, resize, or resequence work based on evidence rather than meeting momentum.
- It reduces rework because assumptions, owners, and review points are explicit enough to challenge.

## 使い方のポイント

- Define the decision, owner, and time horizon before filling in the decision authority map.
- Separate evidence from opinion so the tool supports judgment instead of decorating a preferred answer.
- Record assumptions and review dates because decision speed with accountability changes as the operating context changes.
- Use the output to choose a management action, not merely to produce a document.
- Retire or revise the tool when the decision boundary no longer matches the work.

## 判断するときの注意点

The main risk is false precision: a neat decision authority map can hide weak evidence or political assumptions. Check whether the tool is describing reality or merely rationalizing a decision that has already been made. If the output does not change a priority, owner, resource level, or review date, the analysis is probably too soft.

## よくある誤解 / 落とし穴

- Decision Rights Matrix is not the decision itself; it is a structure for making and reviewing the decision.
- More detail is not automatically better. For Decision Rights Matrix, the useful level is the one that changes a management action.
- A one-time workshop is not enough; the value comes from keeping the artifact current while the decision is live.

## 最小例

A leadership team uses Decision Rights Matrix because recurring decisions stall because authority, escalation, and veto boundaries are unclear. They draft the decision authority map, name one accountable owner, and list the evidence that would change the recommendation. During the Decision Rights Matrix review, one assumption proves weak, so the team narrows the scope and schedules a follow-up review. The Decision Rights Matrix decision record now shows the action taken, the risk accepted, and the signal that would trigger a change.

## FAQ

### What decision should Decision Rights Matrix support?

Decision Rights Matrix should support a specific management choice: what to do, who owns it, what trade-off is accepted, and when the choice will be reviewed.

### How detailed should the decision authority map be?

Decision Rights Matrix should be detailed enough to expose assumptions, ownership, and evidence gaps, but not so detailed that the team stops making decisions.

### How often should Decision Rights Matrix be updated?

Update Decision Rights Matrix when material evidence changes, when ownership changes, or when the review cadence says the decision must be revisited.
