The Commonwealth’s goal is to modernize its applications to ensure vital functions will continue to be supported and improved. The BEST Program has taken a phased approach to this modernization.
The Phase 1 BEST Program replaced the Massachusetts Management Accounting and Reporting System (MMARS) with Mosaic, a modern Software as a Service (SaaS) solution in February 2026.
As part of Phase 2, the BEST Program is working on the long-term replacement of the state’s payroll system, Human Resources/Compensation Management System (HR/CMS), and Human Capital Management functionality operated by agencies (Talent, Recruiting, Learning, Benefits, and Time & Attendance). This work includes implementing Workday, a modern, cloud-based SaaS solution that will make HR and payroll tasks simpler and more accessible.
By adopting modern solutions that prioritize configuration over customization, the Commonwealth will maximize its investment in a new solution by driving efficiency, improving risk controls, and elevating the experience for both employees and residents.
