The client

A leading interactive entertainment and mobile games company with a portfolio of popular, high-quality games across genres. The team makes strategic use of data to optimise game performance, personalise player experiences, and scale.

The problem

The company was undergoing a full transition from Tableau to Looker, driven by the need for a self-service analytics platform. The transition included setting up the Looker infrastructure, migrating all existing analytics processes, executing department-specific projects, and training in-house analysts. Reporting times were prolonged and data accessibility was limited.

How it ran

How the Tableau-to-Looker transition was sequenced so legacy content kept running while the new platform took over.

Step 1

Framework

Worked with data leadership to set the foundational framework for the migration.

Step 2

Roadmap

Defined and maintained a roadmap that introduced Looker without breaking legacy Tableau content.

Step 3

Migration

Migrated reports systematically. Defined scope and prioritised tasks for engineers and analysts on the project.

Step 4

Training

Conducted training sessions for in-house analysts, plus continuous mentoring on Looker development and admin.

Step 5

Onboarding

Onboarded the product department first, then expanded across the company. Looker admin handled throughout.

Result

Outcomes once the central Looker project went live and the team owned it.

Roadmap delivered under 6 months

All Tableau reports migrated into Looker, in-house analysts trained, product team onboarded - the whole transition completed inside the original timeline.

Analysts and product team owning Looker

Trainings plus continuous mentoring made internal analysts capable Looker developers. The product team writes their own explores using full self-service.

Time saving through self-service

Product team answers ad-hoc questions independently. Analysts free up to focus on in-depth work, long-term product strategy, and futureproof explores.
