The ANTOINE CODEX Method

ANTOINE CODEX Problem solving

Find the constraint. Move the business.

Revenue falling or flat, margins under pressure, a process that is too slow: we start from one clear outcome, follow the real work and test the causes before trying a focused change — then we measure its effect.

The problem we look at

Why start with a diagnosis

A symptom is the beginning of the inquiry. The same decline may come from several causes — and need a different response.

Revenue falling or stalling

Fewer qualified opportunities?

Demand • conversion • retention

Margin and cost pressure

Value lost in pricing or delivery?

Price mix • cost to serve • rework

A slow or inefficient process

Where does work wait or repeat?

Handoffs • cycle time • quality

Our starting point: one outcome, a clear owner and a question we can test.

The full engagement, step by step: Business Assessment & Growth Strategy.

The ANTOINE CODEX Method

Five stages, five decisions

Each stage produces a visible output before more resources are committed.

  1. Clarify Formulate the problem

    Turn a complaint into a measurable question: one scope, one measure, one owner and a date to decide.

    Output Problem brief

  2. Observe Data and the real work

    Inspect the numbers and the actual workflow through three lenses: records (CRM, finance, time stamps), people (sales, operations, clients) and real work samples.

    Output Process map

  3. Diagnose Check the causes

    An explanation earns its place through evidence: each possible cause faces a distinguishing test. Only supported causes move forward; unknowns stay visible.

    Output Ranked priorities

  4. Execute A bounded test

    The remedy must match the confirmed cause: one scoped pilot, with an owner and a metric, before any wider roll-out.

    Output Implementation plan

  5. Examine Assess the effect

    Compare with the baseline, account for outside changes and unintended effects, then decide: expand, adjust or stop.

    Output Review memo

What you receive

Visible work, useful decisions

The diagnostic is a defined piece of work with concrete decision materials.

A paid engagement, quoted individually: the actual scope and documents are agreed before it starts.

  1. A clear diagnostic question

    The problem framed as one measurable question, with its scope and its owner.

  2. An established baseline

    Your starting point, measured from your records and the real workflow before anything changes.

  3. Prioritised causes

    Verified causes, ranked and argued; whatever remains uncertain is clearly flagged.

  4. A concrete action plan

    A scoped pilot: the change to test, the roles, the timing and the resources.

  5. A measurable decision criterion

    The measure that will tell you, once the test ends, whether to expand, adjust or stop.

The automated assessment

Two online tools, available at any time: the Quick Business Assessment questionnaire and the AI assistant ("In-depth AI business assessment"). They help you take a first look at your situation, based on your answers.

This initial analysis is based on your answers. It does not replace an in-depth assessment carried out with you and based on your business's actual data.

The in-depth ANTOINE CODEX diagnosis

The method described on this page and in the presentation below. It is carried out by an ANTOINE CODEX team, supervised by Antoine: remotely, on site, or a combination of both, depending on your location and the terms agreed.

It is for business leaders who want an analytical, in-depth review, based on their data and on the real work of their teams.

Schematic situations

Three situations that illustrate the method

Schematic examples • no client data

Revenue B2B sales

More proposals are sent, but fewer become signed work.

What we check
Lead source, response time, loss reasons and offer quality.
Pilot if the cause is confirmed
Redesign one offer step, or assign each request to an owner.
Measure
Win rate and contribution margin.

Margin Cost to serve

Revenue grows while margin erodes: delivery takes more effort than expected.

What we check
Costs broken down by product, client and job; where rework happens.
Possible pilot
Standardise intake and approval for one service, while monitoring quality.
Measure
Cost per job and rework rate.

Process Slow handoffs

A request passes between teams before a proposal goes out: the waiting sits between the steps.

What we check
Where the request waits, and why it comes back incomplete.
Possible pilot
Standardise intake and assign the handoff.
Measure
Cycle time and returned requests.

Illustrative situations, shown to explain the approach: they are not client case studies, and no result is claimed.
