Did It Work?

Outcome qualityHampton Wilson InstituteEVOLVRS ResearchOctober 2026

Public organizations report what they did far more easily than what changed. This brief argues that outcome quality is set before action: define the change, establish where things stand, declare what will be read again, and return to it. Comparable readings show change. On their own, they do not establish cause.

Key findings
  1. 01Outputs are not outcomes.

    Actions completed show delivery. Only a change in conditions answers whether it worked.

  2. 02Outcomes need their context.

    A result read without the structure and process behind it is a number. Read with them, it is evidence.

  3. 03Outcome quality is designed before the work begins.

    Define, baseline and declare first, then read again on comparable terms.

  5. LearnKeep, adjust or stop.

Systems answer slowly. The return is planned before the work, not after.

An outcome read without its structure and process is a number. Read with them, it is evidence.

For leaders

Questions to ask.

Before the next decision reaches the table.

  1. What change is this decision meant to produce?
  2. Where do things stand today?
  3. What will we read again, and on what terms?
  4. What would tell us to adjust, or stop?
