Commercial-off-the-shelf software is the best choice for going forward

• The AoA specified four alternative areas — Status Quo, Commercial-Off-the-Shelf (COTS), Government-Off-the-Shelf (GOTS), and Hybrid (some combination of the other three) — and examined nine possible alternative options.
• The Navy has several viable options, with Alternatives 3 (COTS), 8 (Hybrid Optimize Commercial with Status Quo of Food Service Management and Retail Operations Management systems), and 9 (Hybrid Forward Compatible Commercial) offering the best performance and the lowest cost, schedule, and performance risks. Within the COTS alternative, there are many potential providers.
• The risk-adjusted cost estimates for the COTS alternatives (3, 8, and 9) vary significantly. The higher estimates are nearly twice the cost of the lower estimates, with a spread of more than $200 million. This cost range reflects risk and the variety of integrators and vendors available.

The U.S. Navy operates a 276-vessel battle force, in which each vessel requires a number of supplies for the care and feeding of the crew, the maintenance of the ship, shore-based operations, and operational effectiveness. The Navy uses 16 core information systems to help it manage afloat supply operations for the force. It has indicated that its disparate, antiquated systems have reliability, supportability, maintainability, and affordability problems. Other issues identified relate to the inability to have enterprise visibility into supply operations, cybersecurity demands, and challenges associated with meeting Financial Independent Auditability Review goals. To address these capability gaps in the existing portfolio of systems and to assist in modernizing them, the Department of the Navy asked the RAND Corporation to help in conducting an Analysis of Alternatives (AoA) of its future operational supply, food service, and retail operations capability, known as the Naval Operational Supply System. The study team relied on a series of qualitative and quantitative methods to evaluate the effectiveness, costs, and risks of proposed alternatives within a six-month period of performance.
