In brief
A consultant reference should explain how the adviser investigated a problem and whether the business could use the resulting work. Broad claims of growth or savings can be difficult to attribute to one engagement. Ask about the process, evidence and practical handover while respecting the previous client's confidentiality.

Establish the assignment's relevance
Ask what operating question the consultant addressed, the approximate scope and the client's role in the work. Confirm whether the proposed consultant personally delivered the assignment. A reference about a large corporate strategy project may provide limited evidence for hands-on work with an SME team.
Record differences in business model, staff capability and available data. Similar industry labels do not necessarily mean the same operating problem or implementation constraints.
Explore how findings were developed
Ask whether the consultant reviewed records, observed work and tested assumptions. Find out how it handled evidence that challenged the owner's initial view. A useful adviser should be able to explain uncertainty rather than simply produce recommendations that management expected to hear.
For example, a reference may describe a process delay initially blamed on staff. Ask whether the consultant identified the actual handover or information gap and how that conclusion was validated.
Examine implementation usefulness
Ask what staff received: practical instructions, action owners, training or a pilot plan. Determine whether implementation was part of the engagement or handled internally. A report that was useful for decision-making should not be criticised for lacking implementation work that was never purchased.
Where a change was trialled, ask how the business assessed the result and whether it remained workable after the consultant left. Avoid asking the reference to make unsupported claims about long-term financial impact.
Use the reference as bounded evidence
Record specific observations and limitations. Give the candidate an opportunity to clarify material concerns. Do not treat an unverified complaint as fact or a general compliment as proof that the adviser can solve every business problem.
Combine the reference with the proposed method, named personnel and a clear first-stage scope. If comparable evidence is limited, start with a bounded diagnostic or pilot that produces a usable decision point. The reference check should help the owner understand how the consultant works with a real team, rather than collect an endorsement that substitutes for defining the engagement properly.
