Decision quality is a measure of how well a decision was made at the time it was made, based on the framing, options, information, reasoning, and commitment behind it, rather than on how things turned out. A good decision can produce a poor outcome through bad luck, and a poor decision can produce a good outcome by chance; decision quality separates the two so leaders can actually learn.
Why outcomes are a poor way to judge decisions
Most organizations evaluate decisions by results. That feels fair, but it teaches the unhelpful lessons. A reckless bet that pays off gets rewarded and repeated. A careful, well-reasoned choice that meets bad luck gets punished, and people learn to avoid sensible risks. Over time, judging decisions only by outcomes pushes leaders toward caution, blame, and after-the-fact storytelling.
The alternative is to evaluate the decision process directly. This is not academic. In a McKinsey study of 1,048 major decisions, Dan Lovallo and Olivier Sibony found that process mattered more than analysis by a factor of six in explaining which decisions delivered results. If process drives outcomes, then measuring process is how you improve them.
The six elements of decision quality
A widely used definition comes from the decision analysis field. Strategic Decisions Group describes six requirements and notes that a decision is only as strong as its weakest one:
| Element | Question to ask | Sign of weakness |
|---|---|---|
| Appropriate frame | Are we solving the right problem, with the right scope? | The decision answers a narrower or different question than the one that matters |
| Creative alternatives | Did we consider genuinely different options? | Only one option plus “do nothing” was discussed |
| Meaningful information | Did we use relevant, reliable data, and acknowledge uncertainty? | Key assumptions were never tested |
| Clear values and trade-offs | Do we agree on what we are optimizing for? | People argue about options when they actually disagree about goals |
| Sound reasoning | Does the conclusion follow from the information? | The recommendation came first and the analysis was built to support it |
| Commitment to action | Are the people who must act committed to it? | The decision is announced and then quietly ignored |
How to evaluate the effectiveness of a decision-making process
- Record the decision at the time. Write down the frame, the options considered, the key assumptions, the expected outcome, and how confident you were. Without a record, every review becomes hindsight.
- Review process before outcome. In the review, score each of the six elements first, then look at what happened.
- Separate skill from luck. Ask which outcomes were within the decision makers’ control and which were not.
- Check the commitment. Was the decision actually carried out as agreed? Many “bad decisions” were good decisions that were never implemented.
- Look for patterns across decisions. A single review proves little. Reviewing ten decisions shows whether the team consistently skips alternatives, for example.
Measures of decision-making effectiveness
- Decision speed: time from framing to decision, compared with how reversible the decision was.
- Option breadth: the share of major decisions where three or more real options were considered.
- Assumption accuracy: how often the key assumptions held up.
- Calibration: whether stated confidence matched how often expectations were met.
- Implementation rate: the share of decisions carried out as agreed or openly renegotiated.
- Reversal rate: how often decisions are reopened without new information, a sign of weak commitment.
Decision quality and commitment
The sixth element, commitment to action, is the one most teams underrate and the one DorWay focuses on most. A decision is a set of agreements: who will do what, by when, with what resources, and under what conditions it will be reopened. When those agreements are vague, a well-reasoned decision still fails. We see organizations as a Network of Agreements™, and improving decision quality often starts with making the commitments at the end of each decision specific enough to keep. That is accountability in leadership applied to decisions.

FAQ
What is decision quality?
Decision quality is how well a decision was made at the time, judged by its framing, alternatives, information, values, reasoning, and commitment to action, independent of how the outcome turned out.
What is the difference between a good decision and a good outcome?
A good decision is one made well with the information available. A good outcome is what happened. Luck and factors outside your control mean the two often diverge.
How do you measure the quality of a decision?
Score the decision against the six elements of decision quality using a record made at the time, then compare expectations with results to separate skill from luck.
How can teams improve decision quality?
Record decisions when they are made, require genuine alternatives, test key assumptions, agree on trade-offs before debating options, and close every decision with specific commitments.
