摘要

Existing Systems Engineering Technical Reviews (SETR) are currently reliant on static, document-based Entrance/Exit Criteria (EEC) and Objective Qualifying Evidence (OQE) which is often disjointed and difficult to follow. With the implementation of Model-Based Systems Engineering (MBSE) a more qualitative set of EECs, based on expected levels of Descriptive System Model (DSM) maturity, can be used to evaluate readiness for SETR completion. A paradigm shift of this magnitude requires stakeholder buy-in and input to determine evaluation factors for DSM maturity. The ability to dynamically assess model maturity requires well defined. relation-mapping and methodology. Given the above conditions are met, a metric suite can be established, within a profile, to assess a model's maturity and quality. The metric suite can be applied to any model using the same mapping and methodology. The metric suite probes the model and returns a maturity percentage that can be compared to predetermined, tailorable values. This assessment can then be used to determine readiness for a given SETR milestone.This paper captures a proof of concept experiment for implementing metrics as a portion of Entrance Criteria for a Critical Design Review. A subset of metrics was developed to build stakeholder buy-in, indicating the development of a system has matured sufficiently to be reviewed for a SETR milestone decision. The initial demonstration was well received and there are continuing efforts to improve the ability to assess a model's maturity for SETR milestones. The experiment identified that the metrics are unable to assess against gap information. In contrast, the benefits gained from using a dynamic set of entrance criteria include enabling a more event-based SETR, improved confidence in the model's validity, and can be used to provide more data to assist with effort resource planning.
