Abstract
VAF addresses the globally high failure rate for open Enterprise Information Systems. VAF is based on demonstrated success. Value is modeled as [utility-per-cost] x 1/[development time].
“Utility” means “ability to satisfy requirements.” Requirements are expressed as testable MoP for systems and processes, and MoE for operational execution. The exponential improvement in microprocessor utilityper‐cost predicted by Moore’s Law is a self‐fulfilling prophecy.
Competitive pressure assures the same improvement is reflected in various COTS EIS, e.g. entertainment systems. This discipline can help EIS integrators more generally. IT evolves rapidly, making risks difficult to predict and control. VAF suggests hedging against EIS risks per financial management. VAF suggests also abstracting the traditional systems engineering tools for controlling risk. Contracts should align with VAF.
