The diagnostic journey

A diagnostic moves through recognisable stages: understanding what is actually wrong, testing an explanation, gathering evidence, and turning that evidence into a verdict. It is not data collection, it is a chain of reasoning, and the seven links below describe a way of reading rather than a fixed procedure.

Articles can relate to several stages at once. Wider consulting topics, fees, pricing, selling diagnostic work and professional standards, sit alongside the journey rather than inside it.

Illustration: the seven links of a business diagnostic, hypothesis, lens, questions, evidence, findings, synthesis and verdict, each with the question it answers.
Seven links. The middle ones loop, because revision is part of the method.

Hypothesis

What are we trying to prove?

Name the real problem instead of accepting the presenting symptom, and state what would prove it wrong.

  • Hypothesis or Framework: The Choice You Make Before the Diagnostic Starts7 min read

    We all have a default. Some of us open every engagement with a hypothesis and go straight at it. Others reach for a framework and start filling it in - the SWOT, the five forces, the checklist. Both are legitimate ways to run a diagnostic. The mistake is choosing the mode out of habit instead of...

  • How to Run a Diagnostic Properly - and Where AI Actually Fits9 min read

    Most things sold as a business diagnostic are not diagnostics. They are questionnaires that spit out a score, or thick reports that list everything and conclude nothing. And here is the uncomfortable part for us: plenty of those come from consultants.

Hypothesis-driven work: narrow and deep, aimed at a known spot to test a suspicion and reach a verdict.

Lens

How will we look at it?

Decide whether to go deep on a suspicion or cast a wide net to surface the problem you cannot yet see.

Reading for this stage

Framework-driven work: a wide net cast first to surface the problem nobody can see yet.

Questions

What do we need to know?

Separate questions whose answer already exists from questions whose answer must be worked out.

  • Retrieve or Compute: The Read That Decides Whether AI Helps or Lies11 min read

    A while ago a business owner came to see me, genuinely excited. He had been at a presentation where someone demonstrated an AI tool, and it had stayed with him. The presenter typed in an ordinary question, the tool answered in two seconds, and it even pointed back to the document the answer came...

  • The Depth Behind Real Consulting Advice: Grading a Franchise Against a Tailored Framework7 min read

    A great business spots a new opportunity - say, turning its success into a franchise - and hires a consultant to help capture it. Get generic advice, though, and you can pour months and money into the wrong move and miss the opening. Real advice is the opposite: researched, measured, specific....

Two kinds of questions: find it, where the answer already exists word for word, and work it out, where the answer must be calculated.

Evidence

What does reality say?

Combine desk research with conversations, observation and field work — every number carries a source or a calculation.

  • What They Couldn't Show You: When the Missing Data Is the Finding9 min read

    As a management consultant, I have run business diagnostics more times than I can count, and the same small moment keeps coming back in almost every one. You ask for the number, and it is not there. Nobody can tell you which customers actually make money. There is no org chart. The cash "is in a...

What good evidence looks like: an answer with a named source, or a calculation with the figures shown. Never a guess.

Findings

What did we discover?

Record what the evidence shows, including the gaps — an absence you have confirmed is itself a finding.

  • The Diagnostic Report: A Verdict, Not a Binder7 min read

    You have seen the report. Maybe you have written one. Sixty pages, properly bound, a cover with the client's logo on it, an executive summary that is somehow six pages long.

    Run enough diagnostics in small companies and one root cause comes back more often than any other. It is not pricing. It is not the funnel. It looks like this: every approval waits for one signature, the biggest clients all live in one person's phone, and the whole company quietly holds its...
