How to Choose a Supply Chain Consultant: 7 Questions to Ask Before You Sign

Choosing a supply chain consultant is difficult because the engagement usually fails slowly. The fee is spent before the operation can tell whether anything has changed. These seven questions help separate practical operators from polished sellers.

Questions about the consultant

• What operational role have you actually held? Ask for the company, site, headcount, responsibility, and tenure.

• How much time will you spend on site? Improvement work is a floor sport, so ask for a week-by-week split of on-site and off-site time.

• Who will actually do the work? Get the name and experience of the person who will be on your site in week six, not just the senior person who sold the engagement.

Questions about how they work

• What does the diagnostic include and what does it cost? A proper diagnostic should have a clear duration, deliverables, and standalone value.

• How do you handle root cause when we disagree? Look for a process based on data, review, escalation, and documented decisions.

• What does handover look like, and when does it start? Strong consultants build ownership from day one, not during a final handover meeting.

The question about results

The most revealing question is often the one consultants least expect.

• Can I speak to a client where the engagement did not go to plan?

• Ask what went wrong, how it was handled, and what changed as a result.

• Ask for one success reference and one difficult reference. Speak to both.

• Compare the consultant’s version with the client’s version. Alignment tells you a lot about honesty and accountability.

Final thought

The best consultants welcome hard questions because they know the answers. Choose the provider whose answers you trust, not the one with the shiniest slides.
