The short answer
The findings describe current users but are presented as the whole market. Start with this check: Compare participant recruitment with the population the conclusion claims to represent. The corrective action is to include relevant non-customers where appropriate or narrow the claim to the actual sample.
Key points before you start
The findings describe current users but are presented as the whole market. The useful response is a diagnosis that changes a decision, not another report describing the symptom. Use this play with the research owner and the person using the estimate for a decision. The working evidence should include source method, market boundary and assumption table, with private or sensitive details removed from any shared example.
Confirm the problem in the actual workflow
Compare participant recruitment with the population the conclusion claims to represent. Start with one representative case and follow it from the original action to the reported outcome. Identify where the observed behavior first differs from the intended process. A screenshot of a final dashboard can be useful, but it may hide the source record, a delayed update or a decision made elsewhere.
Keep the unit of analysis explicit: a clearly defined population, period and value measure. The same label can conceal different populations or stages. Before comparing two results, check that they describe the same kind of work and have had a comparable chance to complete it.
Separate the visible symptom from the cause
Read the original definition before combining figures. Publication date, collection period and forecast horizon answer different questions. A market estimate can be useful without being directly comparable to another publisher’s number.
The symptom in this case is specific: the findings describe current users but are presented as the whole market. Ask which piece of evidence would distinguish an operating failure from a measurement failure or a mismatch in the original plan. If the evidence is unavailable, record the missing source and its owner instead of treating the preferred explanation as established fact.
A situation to work through
Existing customers can explain successful adoption while missing the reasons suitable buyers never began an evaluation.
This is an illustrative situation, not a reported client case. Record the equivalent evidence and assumptions for your own workflow.
Choose the smallest useful correction
Include relevant non-customers where appropriate or narrow the claim to the actual sample. Keep the change narrow enough that the responsible people can implement and inspect it. If a correction changes several things at once, describe it as a combined operating change; do not later claim that one small element caused the whole result.
Assign the correction to the research owner and the person using the estimate for a decision. Agree which artifact will show that the work is complete. An owner without an observable acceptance condition can close a task while leaving the original problem unresolved. A detailed checklist without an owner creates the opposite problem: the evidence requirement exists, but nobody is accountable for producing it.
Preserve the important limitation
Customer interviews remain useful even when they are not representative market estimates. This condition belongs beside the recommendation because it can change the decision. It should not disappear when the plan becomes a short presentation or a status update.
A software-revenue estimate and a broader customer-spending estimate may both be credible within their own definitions. Averaging them does not create a better answer. Explain the boundary and choose the measure that matches the decision being made.

Decide whether to keep, revise or stop the change
Review research claims aligned with the recruited population after the agreed observation period. Keep the correction when the intended behavior is verified and the guardrail remains acceptable. Revise it when the diagnosis was useful but the intervention did not resolve the cause. Stop and reassess when new evidence shows that the original problem was framed incorrectly.
Record what changed in source method, market boundary and assumption table. This gives the next review a stable starting point and prevents a definition change from being mistaken for a performance improvement.

Frequently asked questions
What is the first diagnostic check?
Compare participant recruitment with the population the conclusion claims to represent. Inspect the actual working record or customer path rather than relying only on a summary report.
What should change after the diagnosis?
Include relevant non-customers where appropriate or narrow the claim to the actual sample. Record the owner and the evidence needed to verify the correction.
What limit should the team keep visible?
Customer interviews remain useful even when they are not representative market estimates. A local improvement does not establish a universal benchmark or guarantee a commercial result.
How should the correction be evaluated?
Review research claims aligned with the recruited population using a consistent unit and observation window. Keep the original evidence and record any measurement changes.
