Synthesis output

The challenge

An agency faced a decision informed by a large but fragmented body of evidence — studies of varying quality, drawn from different populations and methods. It needed a clear, honest synthesis of what that evidence could support.

Our approach
  1. 01Conducted a structured search and appraised the quality of each source against consistent criteria.
  2. 02Reconciled findings across methods and populations, weighting evidence by strength and relevance.
  3. 03Distinguished what the evidence established firmly from what remained uncertain or contested.
  4. 04Documented the synthesis so its conclusions could be traced, audited and updated.
The outcome

The agency moved from an unmanageable body of literature to a clear, defensible evidence position — one transparent about both its conclusions and its limits.
