| Option | Approach | Cost model | Work your team owns | When to consider it | Trade-off |
|---|---|---|---|---|---|
| Looker | LookML modelling with governed exploration | Request a quote for the deployment and users you need. | Maintain LookML, joins and access filters. | Teams that want centrally defined business metrics. | LookML definitions need translation when you leave. |
| Power BI | Semantic models and interactive reports | Review user licences and capacity together. | DAX, Power Query and workspace governance need an owner. | Teams standardising reporting in Microsoft. | A lower licence bill can still require substantial modelling work. |
How to choose between them
Choose the modelling workflow your data team can maintain: LookML in Looker, or semantic models and DAX in Power BI. If you move, make an explicit inventory of access filters, persistent derived tables and scheduled delivery, then test how each behaves in the target.
Test a report your business already depends on
Choose a report with calculations, restricted data and scheduled delivery. Build it on the shortlisted target and compare the numbers, permissions and operating cost. Ask the finance or operations owner to use it before accepting the result.
Have Rig implement the decision
Rig is a data infrastructure and implementation partner. We audit usage, map the data and logic, then agree a fixed delivery scope. You can keep the warehouse and use a BI tool you choose. Rig Map retains the definitions and dependencies for later reporting and agent work.
When keeping the current tool makes sense
A working reporting setup with known costs may be worth keeping. Replacing software adds rebuild, training and parallel-run costs. Start with the specific reporting problem and compare the cost of fixing it against the cost of moving.
Common questions
Which option is best for our team?
Use the comparison to make a shortlist, then test your actual data, calculations and access rules. The best fit depends on your users, existing models and operating capacity.
Can Rig help without replacing our warehouse?
Yes. Rig can assess and rebuild reporting on your existing warehouse. Agree access, refresh requirements and the target BI tool during discovery.
How much does a migration cost?
Rig maps the work and agrees a fixed delivery price before the migration starts. Source access, custom logic, history and the number of integrations affect the scope. Platform and third-party licence costs are agreed separately.
Can we keep reporting history?
Yes, where the source permits extraction. Agree which history belongs in the target system and which stays in a governed archive. Reconcile both against the original records.
How do you check that the data matches?
Compare record counts, identifiers, relationships and business totals for each wave. Record exceptions and require the business owner to accept the results before cutover.
