Expertises.

An Expertise is a capability ARCHITEKT applies inside an existing organisation. Five expertises carry twenty specialties, and any of them can be bought in six forms: fixed price, time and materials, short placement, long placement, permanent placement, or a named seat.

Five expertises

applied, not delivered beside you
2 specialtiesDesign.Design at ARCHITEKT covers the interface and the process behind it: UX, UI and the design system that keeps them consistent, and the lean rework of the business process the interface is a window onto. It is applied inside the client organisation, in any of six purchasing forms.5 specialtiesProduct.Product at ARCHITEKT covers the full loop: deciding what to build, shipping it, proving it works, improving it on evidence, and the engineering practice that carries it. Five specialties, applied inside the client organisation rather than delivered beside it.8 specialtiesEngineering.Engineering at ARCHITEKT covers eight specialties, from the architecture that structures a decision to the security posture that survives an audit. It is the best-proven expertise in the catalogue, with twenty-two sub-capabilities carrying published evidence.2 specialtiesScale with AI.Scale with AI puts models and agents behind a product decision, with the lineage, the evaluation harness and the boundary that make autonomy engineered rather than hoped for. Two specialties, applied on an estate that has already been made readable.3 specialtiesPerformance.Performance answers three questions about an estate: what it costs, how fast it answers, and what it emits. Three specialties, each measured against a baseline taken before the work starts, because a saving with no baseline is a claim.

What this family is

A capability, applied.

An expertise is a capability applied inside an organisation that already runs. Five of them carry twenty specialties, and any specialty can be bought in six forms — fixed price, time and materials, short placement, long placement, permanent placement, or a named seat.

The five divide by what the work changes. Design changes the interface and the process behind it. Product changes what gets built and whether it worked. Engineering changes the system and the estate it runs on. Scale with AI puts models and agents behind decisions that already exist. Performance answers what an estate costs, how fast it answers and what it emits.

Each specialty is a section on its expertise page, not a page of its own. That is deliberate: a specialty is a declension, and giving nineteen of them their own addresses would produce nineteen thin pages competing with each other for the same queries. The sections are addressable — each has a stable anchor — without being separate documents.

Every specialty page states its proof honestly. A sub-capability is proven when a published case carries a sourced figure, held when a named operator carries it without a case, and declared when it is in scope with nothing published behind it. GreenOps is declared, three sub-capabilities deep, and says so on the page rather than borrowing the credibility of the two beside it.

The six purchasing forms are where most of the negotiation happens, and they are not interchangeable. A design system is rarely bought by the day because its value is in the consistency it enforces over time; a platform team is rarely bought at a fixed price because the scope moves as the estate is understood. Each specialty carries the forms that suit it rather than all six by default.

An expertise is also the honest answer when a client arrives asking for a programme they do not need. Where the destination is already agreed and only the capability is missing, applying that capability inside the existing organisation is cheaper, faster and easier to stop.

What this is not

the boundary, stated

An expertise is not a team for hire. The forms include placement, but a placement is calibrated against a named gap and carries the practice with it.

It is not a transformation. An expertise applies a capability inside an organisation that already runs; when the organisation itself is the thing that has to move, that is a Programme.

It is not a technology menu. The unit is the capability and the proof behind it, not a list of tools — and the tools that appear on these pages are the ones seen on mandates, not the ones a buyer might expect to read.

Six ways to buy

the same expertise, six shapes
Fixed price
A closed scope, a fixed figure, an acceptance condition written before the start.
Time and materials
A capacity bought by the day, against a backlog the client owns and arbitrates.
Short placement
One operator inside the client team for weeks to a few months, on a named gap.
Long placement
The same, over quarters, where the gap is structural rather than a peak of load.
Permanent placement
The operator is recruited into the client organisation; ARCHITEKT holds the search and the calibration.
Named seat
The expertise is carried by an interim C-level seat rather than bought as a capacity.

Each specialty carries the forms that suit it, not all six by default. A design system is rarely bought by the day; a platform team rarely at a fixed price.
