The agency

What a data consultancy covers

This page sets out what a data consultancy engagement covers, how fractional, project and interim compare, how it runs. The board below shows current data leadership roles.

Data consultancy at leadership level is about ownership, not advice. The chief data officer owns data as an asset: strategy, governance, quality, analytics and the platforms behind them.

Fractional Quest is a recruitment agency, not a consulting firm: we do not employ consultants or sell a team. We find a fractional chief data officer or head of data for your brief — fractional, interim or permanent — and they contract with you directly.

Companies searching for a data consultant at leadership level want a fractional data consultant: a chief data officer or head of data who sets strategy and governance a few days a week. See fractional chief data officer.

The scope

What an engagement covers — and what it does not

In scope. The data strategy and how data supports decisions; data governance, ownership and quality; direction of the data platform, warehouse and analytics stack; reporting, analytics and the data team; data protection by design, working with the DPO.

Not in scope. Building pipelines and dashboards is data engineering and analytics work. Legal data protection compliance is the DPO’s independent remit. A data consultant at leadership level directs the first and works with the second.

The neighbouring seats. The CDO owns the value and governance of data; the DPO independently advises on its lawful use; the CTO owns the systems that store it.

When companies look for data consultancy: Every department with its own version of the numbers, an analytics team without direction, an AI ambition with no clean data under it, or a board asking what the data is worth.

The process

How does a brief become a shortlist?

Six steps, one accountable person at each. We don’t promise a shortlist by a date; the weeks below are what a well-scoped brief usually takes.

  1. Day 0
    01
    The 15-minute call
    The seat, the engagement shape, the days or hours, the start date and the budget. No account needed; a call or a written brief.

    Scope agreed in writing
    The outcome the seat exists for, which days, and how the engagement will run for IR35. A brief that describes a person rather than a job, we rewrite with you.

Against the alternatives

Four ways to buy data expertise fractional, project, interim or permanent

The same data problem can be bought four ways. The difference is who does the work, for how long, and who is accountable afterwards.

Fractional data leaderProject consultancy firmInterim executivePermanent hire
What you buyA fractional chief data officer or head of data, days a weekA defined deliverableA leader full-time for a fixed termA full-time leader for years
Who does the workOne named senior personA team, often with a partner who sold itOne named senior personYour employee
Accountable afterYes — they stayNo — the project endsUntil the hand-overYes
Best whenYou need senior judgement every week, not every dayThe work is a one-off with a clear outputYou need full-time cover or a change led nowThe seat is full-time work for years
Usual contractContract for services, often via the leader’s companyStatement of workDay-rate contract for the mandateEmployment contract

The decision

When data consultancy is the right call

Three situations, and the shape that fits each.

  • Many versionsEvery team has its own numbersDepartments argue over whose figures are right. A fractional chief data officer puts ownership and definitions in place.
  • PlatformA warehouse or migrationA data platform build needs a senior owner. An interim data leader takes it full-time to go-live.
  • AI ambitionAI plans without clean dataThe board wants AI; the data under it is not ready. A fractional data leader fixes the foundations first.

Vetting

How do we vet a data consultant?

Five stages before anyone reaches a shortlist of three to five.

  1. Pedigree screen
    Tenure
    We verify prior tenure in the seat, at the scale and stage you need. No consultant presenting as an executive.
  2. Mandate fit
    Fit
    Fit to your stage, sector and the problem the seat exists to solve, not a CV keyword.
  3. Reference deep-dive
    Verify
    We take references ourselves, from recent clients and boards: what they delivered, not what they titled it.
  4. Shortlist
    Shortlist
    Three to five candidates, each with day rate, availability and IR35 position set out.
  5. Kick-off
    Start
    Scope, first-month outcomes and the contract agreed before day one.

The full process is on how we vet.

how it runs

How our data consultancy works from brief to the first ninety days

Brief. A scoping call on the problem, the shape (fractional days, an interim mandate or a permanent seat), the start date and what success looks like in the first ninety days. A good brief names the decisions the data leader will own.

Shortlist. We search for your brief and come back with a shortlist of 3–5, each with day rate or salary, availability and IR35 position set out, assessed through our five-stage vetting.

Contract. You choose; the consultant contracts with you directly, usually through their own company for fractional and interim work. Agree how the engagement will run in practice, because that decides its IR35 status — HMRC’s guidance for clients sets out who makes the determination.

Cadence. A fractional data leader works best on fixed days with a standing slot with the CEO. Review the days each quarter. An interim works to a written mandate with review points and a hand-over date.

fractional or firm

Fractional data consultant or a data consultancy firm? who stays accountable

Data consultancy firms usually sell a build: a warehouse, a dashboard suite, a migration, a model. That work needs a senior owner on your side, or it ends with a platform nobody trusts.

A fractional data consultant is a different purchase: one senior person who holds the brief week after week and answers for the outcome. A fractional chief data officer sets the strategy, governance and platform direction on a standing weekly commitment and lets the analysts and engineers deliver it.

Out of scope either way. Building pipelines and dashboards is data engineering and analytics work. Legal data protection compliance is the DPO’s independent remit. A data consultant at leadership level directs the first and works with the second.

Standing. Check professional standing before you sign: the ICO’s guidance on AI and data protection — how UK GDPR applies to AI systems and to decisions made with AI; BCS, The Chartered Institute for IT — the chartered body for IT, whose Professional Register is a public record of technology professionals.

The right route

Agency, recruiter, interim or permanent?

Three taps. Say how much senior work there is, for how long, and whether it is one leader or a run of hires; the tool names the route.

The route · Fractional executive

Brief a fractional recruitment agency.

Senior judgement for part of the week: a fractional CFO, CTO, CMO or COO on one to three days. We come back with a shortlist of three to five, each with day rate, availability and IR35 position set out.

We recruit executives. We don’t supply embedded fractional recruiters; where that is the right route, the tool says so.
