The Federal Mediation and Conciliation Service (FMCS) seeks firms capable of providing Application Development and Support Services for its Microsoft 365 environment and related systems. The work includes application development, system enhancements, operations and maintenance, and modernization support. This is a market research notice only, not a solicitation, and no contract will be awarded from the responses. The government is considering specific NAICS codes and encourages vendor feedback on a draft Statement of Work to help refine the requirement.
