The Corpus Diagnostic.

Find where the story stops matching reality.
A focused investigation into one important customer decision: what people encounter, what they come to believe, what your organisation can genuinely support, and where those things stop agreeing.

Over three to four weeks, we establish what is happening, why it is happening and what should happen next.

A bounded investigation, not a wandering audit.

Scope

One priority offer, one relevant audience and the journey through which people discover, understand and decide whether to act. The work usually takes three to four weeks.

Investigation

We examine the operational reality, the information people encounter before arrival, what machines appear to infer, what customers come to believe and where the interface confirms or contradicts that story.

Outcome

A clear, evidence-backed diagnosis of where understanding and trust are breaking down, what is causing the failure and which decisions should be made next.

When the visible problem is not the real one.

You may already have a credible website, capable teams and more data than anybody has time to read.

But something still does not add up.

Performance remains weak or fragile. Customers arrive expecting something the experience cannot support. Search results, AI summaries, reviews and third parties describe the organisation differently. Teams keep changing the interface while disagreeing about what is actually wrong.

The symptom may appear on a page, in a journey or in the numbers.

The failure may have begun much earlier.

It may sit in the offer itself, in operational reality, in missing proof, in the wider information environment or in the expectations people have formed before they arrive.
The Corpus Diagnostic is for situations where an organisation no longer trusts its own explanation of what is happening.

When the Diagnostic may be useful.

Changes are not resolving the problem

Redesigns, experiments or content changes have been shipped, but performance remains weak, unstable or difficult to explain.

Expectations collapse on contact

People arrive expecting an offer, experience or outcome that the organisation cannot consistently provide.

The organisation has more than one public identity

The website, search results, AI systems, reviews, directories and third parties present different versions of the organisation or offer.

Teams are acting on competing explanations

Different functions see different causes, so the visible experience keeps changing while the underlying problem remains unresolved.

Not sure where the failure begins?

You do not need a finished brief or an agreed diagnosis.

Bring the symptom, the uncertainty or the question your organisation can no longer answer with confidence. The first conversation is used to establish whether it is suitable for a focused Diagnostic.

What the Diagnostic examines.

People do not arrive at a website empty-headed.

Before they encounter the interface, their understanding has already been shaped by what the organisation can actually deliver, what the wider world says, what machines appear to infer and what they have come to expect.
The Corpus Diagnostic examines five connected layers of that decision environment.

Reality

What is materially and operationally true.

The offer, price, policies, delivery, constraints and outcomes the organisation can genuinely support.

Corpus

What the wider world says and repeats.

Search results, reviews, directories, comparison sites, partner content and public discussion that shape the story before arrival.

Model

What machines appear able to infer.

How search engines, AI systems and other machine-mediated surfaces identify, describe, compare and recommend the organisation or offer.

Human

What people come to believe.

The expectations, assumptions, doubts, risks and decision criteria they carry into the experience.

Interface

Where the story is tested.

The pages, journeys, interactions and communications that confirm those expectations or expose the contradictions beneath them.

The Diagnostic looks for where these layers agree, where they drift, and where trust begins to fail.

How we identify the failure.

The five Corpus layers show where the organisation’s story is being formed, interpreted and tested.
CORPSE triage is then used to identify the mechanism behind the failure:

Claims

What the organisation asks people and machines to believe.

Offer

What the organisation is actually asking people to choose.

Reality

What can genuinely be delivered.

Proof

Why the claims should be believed.

Signals

What the wider environment communicates and reinforces.

Entity

Whether identity, facts and relationships remain stable.

Together, these views separate visible interface symptoms from failures in the offer, operational reality, evidence, external signals or organisational identity.

How the Diagnostic works.

The Diagnostic follows four stages over three to four weeks.

Define

Set the question, audience, offer and boundaries.

Investigate

Examine the available evidence across all five layers.

Diagnose

Identify contradictions, proof gaps and the mechanism behind the failure.

Decide

Prioritise what should change, what needs more evidence and what should remain untouched.
The client is not expected to arrive with a finished diagnosis or perfectly organised evidence. Part of the work is finding, assessing and connecting the information already scattered across the organisation and wider decision environment.

What you receive.

The Corpus Diagnostic does not end with a collection of observations.

It gives you a clear, evidence-backed view of what is happening, where the problem originates and what should happen next.

Five-Layer Decision Map

A concise view of how Reality, Corpus, Model, Human and Interface interact across the selected decision environment.

It shows where the layers agree, where they contradict one another and where the visible problem appears to begin.

Identify the mechanism behind the failure

CORPSE Triage

A structured assessment across Claims, Offer, Reality, Proof, Signals and Entity.

Each area is assessed against the evidence available. Where the evidence is incomplete or disputed, that uncertainty is made explicit rather than filled with confident nonsense.

See exactly where trust is being lost

Contradiction & Proof-Gap Register

A record of where facts conflict, claims exceed the evidence, proof is weak or missing, expectations diverge from delivery, or identity and offer details drift across surfaces.

Each finding includes the evidence, likely consequence, confidence level and required response.

Know what to do first

Prioritised Revival Protocol

A prioritised course of action to stop immediate damage, stabilise the underlying reality and rebuild trust.

It also shows what needs more investigation, what should be monitored, what should remain unchanged and what is already working well enough to protect.

Leave with an agreed decision, not another report

Decision Session and Final Recommendations

A structured working session to verify the findings, resolve factual disputes and agree priorities, ownership and next steps.

The final recommendations record what has been established, what remains uncertain and what should happen first.

Evidence behind the method.

Corpus is a newer consultancy built on more than 20 years of work across research, accessibility, experimentation, digital experience and decision-making.

The evidence currently available for the Diagnostic comes from established professional experience, applied examples and live investigations whose outcomes are still being established.

These forms of evidence are kept distinct. Previous experience is not presented as a completed Corpus engagement, and an investigation is not treated as an outcome before anything has changed.

Established experience

More than two decades investigating how people understand and act within digital experiences, including work where interface problems were traced back to failures in evidence, operations, proposition or organisational understanding.

Applied examples

Real incidents and investigations showing how the Corpus method connects operational reality, external information, machine interpretation, customer expectations and the live experience.

Live investigations

Current work where the method is being applied to an active problem. Findings and outcomes are recorded as they emerge, without pretending the conclusion was known in advance.

Completed Corpus outcomes will be added when there is sufficient evidence to show what changed and what can reasonably be attributed to the work.

Scope and practicalities.

What we need from you

To carry out the Diagnostic, we need:

  • a clear starting concern;
  • access to the evidence that already exists;
  • a small number of people who understand the offer, operations and customer experience;
  • honest constraints;
  • one accountable contact who can help verify facts and keep decisions moving.

Conflicting or incomplete evidence is not a reason to delay. Finding and assessing it is part of the Diagnostic.

Scope

The Diagnostic examines one bounded decision environment: one priority offer, one relevant audience and the journey through which people discover, understand and decide whether to act.

It is designed to investigate that properly, rather than skim the surface of an entire organisation.

Timeframe and fee

The work usually takes three to four weeks.

After the initial conversation, you receive a clear scope, timeframe and fixed fee. If material issues emerge outside the agreed scope, they are recorded and discussed rather than quietly absorbed into the work.

Boundaries and guarantees

The Diagnostic establishes what is happening, where the problem originates and what should happen next.

It does not automatically include redesign, development, large-scale content production, technical remediation, ongoing analytics or implementation. Any follow-on work is separately scoped.

It does not guarantee rankings, AI inclusion, traffic, conversion uplift or a predetermined finding. Its purpose is to replace competing explanations with stronger evidence and a clearer decision.

What happens after the Diagnostic.

The organisation may act on the findings itself, commission a defined follow-on project, investigate an unresolved question or decide that no further work is justified.

The Diagnostic succeeds by supporting a better decision, not by manufacturing another project.

Start with the problem, not a package.

You do not need to know whether the problem is upstream, on-site or both. Bring the problem your organisation can no longer explain with confidence.

The first conversation is used to understand what feels wrong, where it is showing up, what has already been tried and whether the problem is suitable for a focused Diagnostic.

If the Diagnostic is the right fit, you will receive a clear proposal before any work begins. If it is not, we will say so.

Typical first conversations last 45 to 60 minutes and focus on understanding your current situation and constraints.
