Mission Stream Analysis - Delta Analytic Model. Revision

Weapon system program development problems, as evidenced by significant cost increases and schedule delays, highlight the need to improve both the discipline of the development and test processes and the depth of analytic oversight provided for the Department of Defense (DoD) acquisition process. To address these needs, this paper provides two tools to supplement current DoD requirements development and test planning processes. The Delta Analytic Model and companion Mission Stream Analysis are cross-domain analytic tools for enhancing the foundational analysis and the mission effectiveness outcome on major defense acquisition programs. The Delta Analytic Model provides an approach for identifying disparate interpretations of the systems requirements and metrics in the analytic foundation so that the differences can be eliminated; i.e., the model helps minimize the difference (delta) in interpretations of requirements, performance parameters, and metrics by the various communities (design, development, and test). Mission Stream Analysis aids in decomposing the mission and system capabilities/requirements into system technical performance, operator workload requirements, and metrics that contribute to demonstrating mission effectiveness.
