| Summary: | The Navy has developed Distance Support tools to support specific naval systems. These tools often do not facilitate knowledge retention and reutilization; to resolve this problem, a Data Aggregation System (DAS) was recommended to aggregate and integrate data to improve fleet readiness. A systems engineering (SE) process, derived from the 2009 Department of Defense (DoD) SE Model, was used to develop the DAS. Based on past Navy lead Distance Support studies and completed surveys, the team determined the stakeholders needed a data aggregation system that provides 1) easily accessible data, 2) high quality information, 3) current data, 4) well organized information, and 5) information reported on demand. The team conducted requirements analysis to trace and prioritize the system requirements to stakeholders needs. The requirements were then mapped to functions. The high level system functions identified were 1) obtain data, 2) process data, 3) analyze data, 4) report data, and 5) display data. An analysis of Alternatives (AoA) using gap analysis yielded two feasible solutions, 1) modify the Engineering and Supportability Decision System (ESDS) and 2) develop a new system. The results of cost and risk recommended the modified ESDS solution. The solution architecture was documented using Vitechs CORE software suite.
