Documentation That Outlives the People Who Wrote It

Public-sector services outlive the teams that build them. Vendors rotate, staff move, and a service still has to be maintained, audited, and defended years later. That reality changes what documentation is for: it's not a closeout artifact, it's the thing that lets the organization own the product after I'm gone. A PMO carries that continuity risk, so I design the handoff to reduce it. I document the why, not just the what. Which path is the core journey and which is optional depth, and the reasoning behind that split, so future teams don't accidentally complicate the simple path. The accessibility decisions and how they map to WCAG, so conformance survives an audit instead of being rediscovered under pressure. The Design System as the single source of truth, so new contributors extend patterns rather than inventing inconsistent ones that erode the mature, trustworthy feel. I also write for self-service: clear enough that an internal team or the next vendor can act without a meeting, which is the same instinct that reduces call-center load on the citizen side. Good documentation is institutional memory. For a PMO, it's the difference between a maintainable service and a costly rebuild.
