Power BI consultancy for established estates

Onyx Data provides Power BI consulting services for established Power BI estates with performance, semantic-model, refresh, ownership or release-process problems.

Our Power BI consultants start from that problem and the decision behind it, then recommend the smallest engagement that resolves it.

Onyx Data is a London-based Microsoft Solutions Partner for Data & AI, founded by Microsoft MVP Leon Gordon.

What our Power BI consultants work on

  • Performance: reports and visuals that are too slow for the people who use them.
  • Semantic models: model problems behind slow, inconsistent or hard-to-change reports.
  • Refresh: refreshes that fail or run too long.
  • Ownership: workspaces, models and reports with no clear owner.
  • Release process: no reliable way to move changes from development to production.

If the next decision is about Microsoft Fabric, see Strategy & Enablement. If your team needs skills, see Onyx Academy training.

How a Power BI engagement starts

  1. Tell us the problem and the deadline

    We reconstruct the trigger and its consequence: what is failing, for whom, and by when it has to be resolved.

  2. Identify the owner and approvers

    We identify the decision owner, the champion and the people who need to approve the work.

  3. Check evidence and access

    We check that the evidence and access the work needs are available, and what security and procurement require.

  4. Agree the smallest scope that resolves it

    We recommend the smallest engagement capable of resolving the decision.
