Army Information Technology Procurement: A Business Process Analysis, Alexander M. Vukcevic
Army Information Technology Procurement: A Business Process Analysis, Alexander M. Vukcevic
Theses and Dissertations
This thesis presents a business process analysis of the Army's ICT procurement system. The research identified several inefficiencies and proposes several potential solutions. the contributions of this research include a unified taxonomy, a method to prioritize requests, and system architecture products for development of an automated and sustainable collaboration interface for the CIO/G6 to streamline their IT acquisition process. Development of a centralized system would reduce waste in the request process from submission to formal accounting, hasten the movement of requests between stakeholders, maintain a digital signature authorization for each approval authority, provide a reporting database to recognize reprogramming thresholds, …

Improving The Enterprise Requirements And Acquisition Model's Development Test And Evaluation Process Fidelity, Jason W. Sutherlin
Theses and Dissertations
Shrinking budgets and dynamic military conflicts have driven Department of Defense (DoD) leadership to reform how the military acquires weapon systems with the goal of decreasing program schedules and costs, while maximizing performance. With fifty years of reform, the DoD has been unable to adequately control program schedule objectives. Previous research attempted to support acquisition reforms through modeling and simulation. The Enterprise Requirements and Acquisition Model (ERAM) captures a program's progression through the Defense Acquisition Management System to gain insight into significant delays that impact program schedule and probability of completion. A past unexpected result included the insignificant impact that …

Enterprise Requirements And Acquisition Model, David A. Leach, Chad T. Searle
Theses and Dissertations
In support of senior leadership emphasis on improving early systems engineering and analysis, the Enterprise Requirements and Acquisition Model (ERAM) is a quantitative discrete-event process simulation model that accounts for activities from the identification of a desired space capability early in the JCIDS process through Milestone C of the acquisition system resulting in a probabilistic schedule distribution for a given concept. This model of the DoD's space capability development process will provide valuable decision making information for Concept Characterization and Technical Descriptions referenced during Analysis of Alternatives. The research focused on identifying activities, assigning historical triangular distributions and probabilities at …
