After months of rigorous schedule rebaselining efforts, One Washington (OneWA) announced the updated Phase 1A go-live date range: October 2027 through October 2028. At a high level, this range reflects OneWA’s commitment to a disciplined, realistic path to enterprise readiness while maintaining clear accountability and transparency. It defines a window to manage risk, monitor progress through planned checkpoints, and make informed decisions— without changing the expectation that OneWA will have a single, enterprise-wide go-live, with all agencies moving together and shared accountability for readiness and outcomes
What the go-live date range means:
- OneWA is planning and working toward the earliest date in the range—together.
The program schedule is currently built to support the first available go-live window (October 2027), and agency planning and support activities align to that target. - The range gives the program structured opportunities to check readiness and adjust as needed.
Built-in checkpoints allow the program and agencies to assess progress, surface risks early, and make informed, enterprise-level decisions about readiness for a given date. - Go-live dates occur within defined enterprise windows.
The available go-live windows are October, April, July, or October, and decisions about moving to a later window are made through program governance based on collective readiness.
What the go-live date range does not mean:
- It does not change the enterprise go-live approach.
Phase 1A remains a single, coordinated enterprise go-live, not a staggered or agency-by-agency deployment. - It does not mean agencies select their own go-live date.
Dates are determined at the enterprise level to ensure system stability, integration readiness, and statewide operational continuity. - It does not include January as a possible go-live window.
January is intentionally excluded due to elevated risk from HRMS and AFRS year-end processing and system changes during that period.
