Phase 1A Project Schedule

A schedule is a map of the network of tasks that must be completed to deliver a complex outcome like the replacement of the state’s core financial administrative services. It is a model that will be a fundamental tool for managing the work and delivering the desired result on behalf of the state. 

One Washington has created a portfolio of schedules to:  

  • Ensure all the work of the program is described—no invisible work.

  • Identify the resources required to complete the work of the program and enable the program to monitor and manage this capacity.

  • Be used by every team member every day to guide us on the work that needs to be accomplished and when.

  • Understand the relationship between tasks and workstreams and how they are interrelated to the project as a whole, thus strengthening our collaboration. 

  • Model downstream and cascading effects when tasks fall behind, or when we learn of new needs, new information, or other surprises.

  • Strategize how to overcome real and potential barriers to project success.

  • The schedules will serve as the foundation for managing the work of One Washington and driving our results.
