The symptom is a starting point
An unclear website, an inconsistent identity or a difficult sales conversation gives a project something visible to address. I take that signal seriously. I also want to understand the conditions producing it. The same visible symptom can emerge from an unclear offer, a poorly chosen audience, contradictory internal priorities or an execution problem. Each explanation suggests a different intervention.
For me, diagnosis is the work of making that distinction useful. It connects an observed condition to a reasoned account of what deserves attention next. The ambition is practical: to help the business choose where to act. A diagnosis that merely renames the symptom leaves the original commissioning decision almost exactly where it began.
Follow the contradiction
I pay particular attention to places where two parts of a business make incompatible demands. An offer may promise close involvement while the buying journey emphasises immediate self-service. A company may seek a more specialised audience while retaining language designed to include everyone. Those tensions can make individual pieces look weak even when each has been competently produced.
The contradiction provides a question to investigate. Which promise should govern the experience? Which audience has priority when their needs diverge? What must the business actually deliver for its language to remain credible? Looking across the whole journey helps locate the decision underneath the visible inconsistency. That decision gives subsequent creative work a clearer purpose.
Make the reasoning inspectable
A useful diagnosis should allow the client to follow the reasoning. I want to show the observation, the interpretation and the implication for action. If the homepage introduces several audiences with equal emphasis, that is visible. Whether this causes hesitation requires further examination. Keeping those statements separate makes the argument easier to discuss and the work easier to correct.
Confidence should be proportionate to the material available. Existing documents can reveal contradictions. Conversations can supply context. Looking at the customer journey can expose a missing explanation. Each source answers some questions and leaves others open. I prefer a diagnosis with explicit boundaries because it lets a decision maker see exactly what the proposed intervention depends on.
Choose the level of intervention
The prescription should follow the cause at a scale the business can carry. Sometimes the work is concentrated: clarify an offer, reorder a page, equip a sales conversation. Sometimes the problem reaches further into how the company presents and organises itself. Choosing the right level matters because a wider commission also introduces more dependencies, more decisions and more responsibility for maintenance.
I ask what must change for the proposed work to make sense. If a new identity depends on an unresolved offer decision, that dependency belongs in the plan. If a modest clarification can be tried before a larger commitment, it deserves consideration. The sequence should help the client learn while preserving a clear reason for every piece of work.
Give the diagnosis an exit
Diagnosis needs a point at which it becomes a decision. I look for sufficient clarity about the problem, the priority and the next action, along with an honest account of the remaining uncertainty. The output should make it possible to commission work, change an internal choice or pursue a specific question with a defined purpose.
That is the standard I want the practice to meet. The client should leave able to explain why this intervention deserves attention now and what would make it worth continuing. Diagnosis earns its commercial value through that change in judgement. The document is useful because of the better decision it makes possible and the work that can finally proceed with a reason.
