An Evaluation Of Schedule Metrics Used Within Aeronautical Systems Center, Robert J. Hayes, Lawrence M. Miller Sep 1992

An Evaluation Of Schedule Metrics Used Within Aeronautical Systems Center, Robert J. Hayes, Lawrence M. Miller

Theses and Dissertations

This study focused on a selected group of schedule metrics in use at Aeronautical Systems Center (ASC) acquisition program offices. Over 300 metrics were collected from the System Program Offices (SPOs). The metrics data were sorted into the categories of cost, schedule, and performance. In order to narrow the scope of the project, the team decided to focus on schedule metrics. Seven of the most common schedule metrics were selected for evaluation by a group of five experienced acquisition professionals. The group was asked to input the likely behaviors driven by the metrics being addressed by the study. Next, they …


An Analysis Of Strategic Planning To Support The United States Special Operations Forces' C3 Interoperability, George M. Pierce Ii Sep 1992

An Analysis Of Strategic Planning To Support The United States Special Operations Forces' C3 Interoperability, George M. Pierce Ii

Theses and Dissertations

The purpose of this study was to analyze the strategic plans of USSOCOM to determine its role in resolving the C3 interoperability issues. A model using strategic controls and Theory of Constraints was used as a standard to evaluate USSOCOM's management plans. A literature search revealed that hardware and new technology were the primary concerns of previous studies. However, the literature did not address whether the lack of a formal strategy contributed to the C3 interoperability problems. Therefore, the determination was to adopt a fresh approach to the C3 interoperability issues and analyze the strategic process. The data analysis of …


Review Of Factors Impacting Warranty Cost-Benefit Analysis For The Sensor Fuzed Weapon System, Donna E. Kehrt Sep 1992

Review Of Factors Impacting Warranty Cost-Benefit Analysis For The Sensor Fuzed Weapon System, Donna E. Kehrt

Theses and Dissertations

The purpose of this research effort was to identify factor that affect the warranty cost-benefit analysis for the Sensor Fuzed Weapon (SFW) system since an essential performance requirement (EPR) warranty waiver was under consideration. Defense funding has become scarce, and the limited dollars must be spent wisely. A cost-benefit analysis should provide a relevant projection of cost-effectiveness based on the best available data. The SFW and other dormant weapon systems present difficulties in determining cost- effectiveness because the systems most probably will be non-operating, non- reusable, and non-restorable. Three recommendations were made, relevant to dormant weapon systems, that pertained to …


Software Cost Estimating Models: A Calibration, Validation, And Comparison, Gerald L. Ourada Dec 1991

Software Cost Estimating Models: A Calibration, Validation, And Comparison, Gerald L. Ourada

Theses and Dissertations

This study was a calibration, validation and comparison of four software effort estimation models. The four models evaluated were REVIC, SASET, SEER, and COSTMODL. A historical database was obtained from Space Systems Division, in Los Angeles, and used as the input data. Two software environments were selected, one used to calibrate and validate the models outside their environment of calibration. REVIC and COSTMODL are COCOMO derivatives and were calibrated using Dr. Boehm's procedure. SASET and SEER were found to be un-calibratable for this effort. Accuracy of all the models was significantly low; none of the models performed better against the …


Relative Utility Of Selected Software Requirement Metrics, James H. Byers Dec 1991

Relative Utility Of Selected Software Requirement Metrics, James H. Byers

Theses and Dissertations

The objective of this study was to determine the relative utility of selected software requirement metrics in assessing the productivity of the software requirements analysis process and the quality of the products of this process. This objective was met by collecting information about the perceptions that practicing software professionals have of the usefulness of various requirement metrics. The study employed a two part methodology. The first part utilized Basili's goal/question/metric paradigm to identify specific goals of the measurement effort and to identify requirement metrics worthy of further investigation. The second part employed a typical research design to gather perceptions that …
