Evidence from assessments and advisory work

The assessment flagged that our overnight finance extract and the product event stream shared a single brittle job — something we had argued about for months without proof. The written sequencing made budget talks shorter.

Advisory workshops were concrete: interface contracts, late-data handling, and who owns retries. We still had to staff the build ourselves, which was clear from the start.

Dual-run guidance kept our Monday trading pack on schedule while we swapped marts. One reconciliation alert was noisier than we liked in week two, but the cutover checklist held.

Observability work focused on the five datasets that actually wake people up. We declined a longer catalogue for now and that restraint helped adoption.

Retail finance pack and a shared overnight job

A regional retailer asked for a platform assessment after three consecutive Mondays where the commercial pack landed late. Discovery showed finance extracts and product events sharing one orchestration graph with a single retry policy. We separated schedules on paper first, scored risk by domain, and left a 90-day sequence the internal team executed without staff augmentation. The mild reservation from their analytics lead: interviews took longer than hoped because access tickets lagged.

Logistics mart cutover with dual-run discipline

A logistics BI group needed warehouse modernisation without freezing trading reports. We ranked measures leadership quotes in meetings, automated dual-run diffs for revenue and active accounts, and kept secondary dimensions for a later wave. Cutover week used published day rates for on-site support. One reconciliation alert fired noisily in week two; the checklist still held and the old mart was retired on schedule.
