SYSTEMS ANALYSIS QUALITY METRICS

THIS RESEARCH WILL DEVELOP AN EXTENSIVE SET OF QUALITY METRICS FOR THE EVALUATION OF IDEF MODEL QUALITY, INPARTICULAR, AND FOR THE EVALUATION OF SYSTEMS ANALYSIS MODEL QUALITY, IN GENERAL. THE RESEARCH IS THE CONTINUATION OF INVESTIGATIONS ALREADY PERFORMED BY THE PRINCIPAL INVESTIGATOR, MR. WILLIAM R. WILLIAMSON, UNDER INTERNAL COMPANY FUNDING. THE SPECIFIC METHODOLOGY, IDEF, WAS CHOSEN FOR THE RESEARCH BECAUSE OF ITS DIRECT APPLICABILITY TO PREMILESTONE IO PLANNING. IDEF IS THE MOST WIDELY USED METHODOLOGY WITHIN THE DOD FOR CONCEPT DEFINITION AND FOR REQUIREMENTS ANALYSIS AND SPECIFICATION. THE KEY PRODUCT OF THIS RESEARCH IS A SET OF QUALITY METRICS WHICH GOES FAR BEYOND EDITING CONSIDERATIONS SUCH AS LABELING, DRAFTING AND COMPLIANCE WITH MODELING RULES. THE METRICS WILL EVALUATE MODEL DECOMPOSITION QUALITY, PRECEDENCE RELATIONSHIPS, CONSTRAINT VS FLOW CONFLICTS, GENERIC VS SPECIFIC CONTENT, AND MODEL COMPLEXITY. THE RESEARCH PRODUCTS WILL BE SPECIFIC AND GENERIC QUALITY METRICS, METHODOLOGY FORMALIZATION ENHANCEMENTS, IDENTIFICATION OF MACHINE DETECTABLE QUALITY FACTORS, AND TRAINING MATERIALS.
