- W2950953405 abstract "The United States Coast Guard (USCG) is undertakingan enterprise-wide Financial Management Business ProcessRe-Engineering (FM BPR) effort that will transform its delivery offinancial management services which support worldwide operationsand mission support activities. The planned changes will includedeployment of new commercial-off-the-shelf financial managementsoftware, and simultaneous changes to USCG organizationalstructures and FM processes. Proposed changes to the USCG FM systemare intended to bring the Service into compliance with Federalstandards for financial operations, while simultaneously improvingdelivery of financial business support to end users. This thesisapplies Dr. Nancy Leveson's System Theoretic Process Analysis(STPA) safety methodology to perform a hazard analysis on aspectsof the re-engineered (future state) business processes to helpensure the system can deliver its intended performance. Applicationof STPA on the USCG FM system was conducted with the aid of theSafety Hazard Analysis Tool (SafetyHAT) software released in March2014 by the Volpe National Transportation Systems Center. SafetyHATis intended to aid users in performing hazard analysis using STPA.The use of SafetyHAT for this thesis research is its firstapplication outside of the Volpe Center and transportation domain.Recommendations for tailoring the tool to the financial managementand other domains are proposed. The application of STPA on targetedaspects of the USCG FM system identified 205 causal factors forpotential system hazards. Recommendations to appropriatelyremediate the causal factors are proposed based on systems theoryprinciples and tools. Recommended improvements include robustfeedback and communication channels illustrated using the systemcontrol diagram used to perform STPA. System dynamics modeling isalso used to quantitatively illustrate the non-linear interactionsthat exist in the USCG FM system, and how the system design willaffect its performance over time. The simulations show that if thecausal factors identified using STPA are not addressed, the FMsystem may fail to achieve its intended performance. Otherrecommendations include the expanded use of system dynamic modelingto inform future design decisions for the USCG FM system, includingtrade-offs driven by resource limitations, as the re-engineeringeffort progresses." @default.
