6. NOTES
6.1 Shared Database
A key to improvement in the design, integration, and test process is the ability to provide product life cycle information to the various technical and management disciplines. Availability of product life cycle data will greatly enhance program performance goals in terms of product improvement, cost savings, and schedule optimization.
Product improvements, test process improvements, and associated cost benefits can only be fully realized if the necessary data are documented in an easily retrievable electronic format. This can best be accomplished by industry support of a common set of data with standardized formats.
The development and use of an industry-wide product life cycle database will reduce the costs of sharing data and provide a means for quantitative test process improvement. A minimum set of data using a common database format is required to accommodate these goals.
The Space Systems Engineering Database at the Aerospace Corporation is an enterprise wide relational information system suitable for management of project data. The SSED data model uses ISO 10303 Standard for Exchange of Product Model Data that provides complete, unambiguous, computer interpretable data for each constituent of a product throughout its life cycle (from conceptual to orbital operation).
6.2 Guidance Tables. Programs may use the programmatic factors listed in Table 1 when establishing testing requirements. Consideration of a test program also incorporates knowledge of the possible failure cause or type. Table 2 contains a comprehensive list of failure cause or type for the various units and subsystems comprising space hardware. Once failure mechanism is determined, the environmental qualification test listed in Table 3 provide means of detecting the defect. The primary acceptance test to precipitate failure mechanisms are given in Table 4.
