Sustainment and Net-ready Key Performance Parameters (KPP) in an Enterprise Information System (EIS) Value Assurance Framework (VAF)

摘要

The Enterprise Information System (EIS) Value Assurance Framework (VAF) is an Information Technology (IT) governance model based on commercial best practice adapted to specific DoD and Intelligence Community (IC) acquisition policy requirements. VAF expands and abstracts traditional DoD 'Availability' metrics such as 'Operational Availability' to develop objective time-based Key Performance Parameters (KPP) appropriate for software-intensive systems of systems. In particular VAF addresses both the DoD 'Sustainment KPP' (S-KPP) and the 'Net-Ready KPP' (NR-KPP). Hence, VAF provides an engineering assurance model for developing systems that deliver sustainable information superiority. In the VAF construct, the NR-KPP correlates measurable improvement in 'Information Processing Efficiency' (IPE) to measurable improvement in traditional operational effect metrics such as Probability of Kill (Pk). In addition to that focus on operational efficiency, VAF recognizes that sustainment of modern IT systems requires process-level metrics that enforce speed-to-capability requirements. Hence VAF S-KPPs specify both threshold and objective speed-to-capability requirements commensurate with 'Moore's Law.' To achieve aggressive speed-to-capability, the VAF S-KPPs emphasize re-use of pre- certified COTS and GOTS components. The VAF addresses both of these types of KPPs through a recommended iterative process, consisting of 10 steps. Applying this process to a notional coalition counter-insurgency mission thread demonstrates its viability.
