Mission Driven SaaS Implementation

529 cloud services already hold a federal authorization. Where one of them sits close to how an agency already works, adopting it means inheriting the provider’s security controls, patching cadence, and upgrade path instead of building and then sustaining all three.

It also sheds a long tail of obligations that outlast any single program: code to maintain, dependencies to patch, re-accreditation to run every few years, and staff to keep on all of it.

A platform arrives generic and an agency’s process is not. The workflow that matters is usually an exception path, the one handling a case a statute created, and it surfaces during configuration rather than in a demonstration.

Data is the other half of it. Records that accumulated in a legacy system across two decades do not map cleanly onto a commercial schema, and reconciling them becomes discovered work rather than planned work.

Agencies also lack the evidence to judge the result. GAO reported in 2026 that agencies do not have comprehensive data on how well shared services are meeting their needs, including the cost avoidance those services were meant to deliver.

Configuration depth against customization decides the upgrade path. Every customization is a change the provider did not anticipate and does not test, and federal systems run long enough to meet every upgrade.

Exception paths belong in the design rather than in a workaround. Where a platform cannot express a rule an agency is legally required to apply, that gap is better solved at the integration layer, where it can be maintained and inspected.

Adoption decides whether the rest of it counts, and the measure is whether people stop using the process the platform was bought to replace.

At OCH we work across the platforms federal agencies have already authorized. The implementation discipline does not change with the product; what changes is where the configuration limits sit and how much has to be built around them.

We map the real workflow first, exception paths included, against how the platform actually behaves rather than how its documentation describes it.

We stage data migration in defined steps, profiling, cleansing, mapping, dry running, reconciling, and then cutting over, and we deliver the reconciliation output to the customer rather than keeping it as an internal check.

We solve genuine gaps at the integration layer instead of inside the platform, which keeps the upgrade path open for as long as the agency owns the system.

We scope role mapping, training, and a support path from the start rather than treating adoption as a final phase.
