Data silos between agencies block one-stop public services

Solution case studies are scenarios based on common industry problem patterns. They do not refer to any client and are not MarkasDev project portfolio items. Our client portfolio is published separately.
Industry context
A local government wants integrated public services, but population, permit, and levy data live in separate systems with no shared master reference.
Constraints
- National e-government (SPBE) policy
- Agency mandates
- Rigid annual budgets
- A different vendor per agency
Approach
Diagnose
Pick a priority service use case, map the data domains, and agree on data ownership.
Deliver
APIs or events for the chosen use case and a limited master reference, rather than an instant government data lake.
Operate
A data steward forum, SLAs between agencies, and an API catalogue.
High-level architecture
Integration layer + API gateway + a small reference data service.
Typical outcomes
One cross-agency service flow runs end to end for the priority use case.
Typical or expected outcomes, not claims about MarkasDev project results.
