Abstract

Acceptability criteria establish the measures against which to judge the appropriateness of a simulation for an intended use. The quality of any products from VV&A processes depend directly upon the quality of the acceptability criteria they use. Much is written on the properties of good acceptability criteria but little advice exists in this literature for how to develop them. This paper describes one effort to develop the acceptability criteria for a major simulation development program and the lessons learned from that effort. The process that this effort employed involved decomposing the information in the available requirements documents (i.e., a Capability Development Document, a Performance Specification and a requirements model) into individual requirements statements, determining from those statements the required functional and system capabilities, identifying any requirements that define specific performance metrics, integrating that information into observable acceptability thresholds and checking the consistency of those thresholds with the other acceptability criteria and the original requirements statements. The resulting acceptability criteria were then circulated amongst a group of subject matter experts to verify the necessity and completeness of their characterization of the users' needs. This process produced high-resolution, traceable and defensible acceptability criteria that could supply detailed insight into the simulation's capabilities in the context of a user's needs. However, many outside factors can influence the acceptability criteria process including program office preferences, testing limitations, developer concerns and user representative concerns. All of these factors must be mediated to produce acceptability criteria that are acceptable to a majority of these influential players.
