Decision type matrix

The decision it supports

Use the decision type matrix to compare unlike items without forcing them into one undifferentiated ranking. The working view makes reversibility axis, materiality axis, and four decision types visible so discussion can move from general opinion to a specific action or decision.

When to map the portfolio

Use the decision type matrix when a list in decision systems contains materially different cases that should not receive the same response. The matrix is useful only when the anchors for reversibility axis, materiality axis, and four decision types can be supported with evidence.

How the matrix works

The decision type matrix is a two-dimensional comparison that gives different positions different management responses. Its core working elements are reversibility axis, materiality axis, four decision types, and evidence bar. Those elements belong together because each changes how the others should be interpreted or acted on.

Axes and responses

Reversibility axis

Capture reversibility axis only at the level needed to answer: How much rigor should a decision receive based on reversibility and materiality? Use observable evidence, name any unresolved judgment, and state what action or choice this entry can change. Within the decision type matrix, connect this entry to materiality axis so the relationship can be reviewed rather than inferred.

Materiality axis

Use explicit criteria rather than intuition alone, and preserve the reason that one item ranks above another. Within the decision type matrix, connect this entry to four decision types so the relationship can be reviewed rather than inferred.

Four decision types

Name the decision, the person or body with final authority, the date, and the rationale that should remain visible later. Within the decision type matrix, connect this entry to evidence bar so the relationship can be reviewed rather than inferred.

Evidence bar

Name the evidence, its date and owner, and any limitation that affects how confidently it can be used. Within the decision type matrix, connect this entry to approval path so the relationship can be reviewed rather than inferred.

Approval path

Name the decision, the person or body with final authority, the date, and the rationale that should remain visible later. Within the decision type matrix, connect this entry to expected speed so the relationship can be reviewed rather than inferred.

Expected speed

Capture expected speed only at the level needed to answer: How much rigor should a decision receive based on reversibility and materiality? Use observable evidence, name any unresolved judgment, and state what action or choice this entry can change. Within the decision type matrix, connect this entry to approval path so the relationship can be reviewed rather than inferred.
