Service 04 // Data & analytics

One set of numbers everyone trusts.

We connect the systems and spreadsheets your business runs on, model the data properly and put clear dashboards in front of the people who make decisions.

// 01 — What's included

From scattered sources to clear answers.

Good reporting is mostly plumbing. We build the plumbing properly so dashboards stay right after the people who built them have moved on.

01

Data audit

An inventory of your sources, owners, definitions and quality issues, with a prioritised plan.

02

Ingestion pipelines

Scheduled, monitored syncs from apps, databases, APIs and spreadsheets into one place — with retries and alerts.

03

Warehouse design

A cloud warehouse sized for your volume and budget, with sensible security and cost controls.

04

Modelling with tests

Business logic written once in version-controlled models, with tests that catch broken data before it reaches a report.

05

Dashboards & self-service

Focused dashboards for each team, and a governed layer so analysts can explore without breaking things.

06

Data for AI

Clean, documented tables ready to feed forecasting models or AI assistants.

// 02 — Deliverables

What you walk away with.

A documented data platform, not a pile of one-off reports.

  • Source inventory and data audit
  • Automated ingestion pipelines
  • Cloud data warehouse
  • Tested, documented data models
  • Agreed metric definitions
  • Team dashboards
  • Data-quality alerts
  • Handover and training sessions
// 03 — Example use cases

Where it pays off.

Common data problems we're set up to solve. These are illustrations, not client case studies.

Use case 01

Board and management reporting

Monthly packs that used to take days of copy-paste, generated automatically from source systems.

Use case 02

Single customer view

Orders, support tickets and marketing data joined on one customer record, so teams stop arguing over whose number is right.

Use case 03

Operational dashboards

Near-real-time views of stock, jobs, bookings or deliveries for the people running the day.

Use case 04

Forecasting

Demand, cash-flow or capacity forecasts built on clean history, with clear explanations of their uncertainty.

// 04 — Process

How a data project runs.

01

Audit

Interview stakeholders, list sources and agree the questions that matter most and how each metric is defined.

→ metric definitions
02

Foundation

Set up warehouse, ingestion and the first models, with tests and documentation from the start.

→ first pipelines
03

Dashboards

Ship the first dashboard for one team quickly, gather feedback, then extend to the next.

→ first dashboard
04

Hand over

Training, runbooks and monitoring — or an ongoing plan where we keep it running for you.

→ self-sufficient team

// 06 — FAQ

Common questions.

Something not covered? Write to hello@spellegrinokey.co.uk.

We mostly use spreadsheets. Is that a problem?

Not at all — it's a very common starting point. We can ingest spreadsheets on a schedule, then gradually replace the most fragile ones with data pulled straight from your systems.

Which BI tool should we use?

The one your team will open. If you already have Power BI or Looker, we build on it; if not, we often suggest an open-source option such as Metabase to keep licence costs low.

How do you make sure the numbers are right?

Business rules live in version-controlled models with automated tests, metric definitions are agreed and documented with the people who own them, and alerts fire when source data looks wrong.

Is our data secure?

Data stays in a warehouse in your own cloud account, with role-based access, encryption and audit logs. We follow UK GDPR principles such as data minimisation and retention limits.
