Advisory & Architecture · Fractional

Senior data architecture, a fraction of the time.

Most organizations need a data architect's judgment a few days a month — not a salary's worth. A fractional architect owns your data blueprint, reviews every build against it, and keeps each project pointed at the same foundation.

The mechanism

Architecture is a continuous role. The workload isn't.

Decisions about platforms, models, and governance arrive in bursts — a migration here, a new reporting request there. Between bursts, the role is oversight: keeping changes consistent with the blueprint. Paying full-time for burst-shaped work is where the money leaks.

A fractional arrangement matches cost to the actual shape of the work — and because the same architect stays with you, the context never resets.

Scope

What the architect owns

The blueprint

One documented target architecture — platforms, data flows, modelling standards — that every project builds toward instead of around.

Decision records

Why each significant choice was made, written down. New hires and new vendors inherit reasoning, not folklore.

Design review

Proposed changes and vendor deliverables checked against the blueprint before they harden into technical debt.

Governance guardrails

Access, classification, and quality rules defined once at the architecture level — so each project doesn't reinvent them.

Platform choices

Fabric, Azure, Databricks, or something else — evaluated against your workload and team, not against a vendor's roadmap.

Team capability

Your engineers and analysts learn the reasoning behind the design, so dependence on the architect goes down over time.

Engagement shapes

Three ways it typically runs

The cadence flexes with the work. Most clients start with one shape and move between them as projects ramp up and down.

01

Advisory cadence

1–2 days / week

Steady-state oversight. The architect reviews changes, keeps the blueprint current, and joins the decisions that matter.

  • Monthly architecture review
  • Decision records maintained
  • On call for design questions
02

Embedded sprint

2–3 days / week, time-boxed

For a migration, platform selection, or major build. The architect works inside the project team until the design is landed.

  • Target design produced
  • Build reviewed as it lands
  • Handover to advisory cadence
03

Design authority

standing role

When multiple vendors or teams build in parallel, the architect acts as the single gate their designs must pass through.

  • Review gate for all designs
  • Cross-team consistency
  • Vendor accountability
A straight answer

When it fits — and when it doesn't

A good fit when

  • Data decisions are being made project-by-project, with no one holding the whole picture.
  • Vendors or contractors deliver work no one on your side can properly review.
  • You're heading into a platform decision — Fabric, Azure, Databricks — and want judgment that isn't selling one.
  • A full-time architect isn't justified yet, but the mistakes of not having one are getting expensive.

Probably not when

  • You already have a strong architect in-house — they may just need a sounding board, which is a smaller engagement.
  • The work is sustained heavy build for a year or more; at that volume a full-time hire is usually the better economics, and we'll say so.
  • What's actually missing is engineering hands, not architectural judgment.
