End To End Analysis

Decent Essays

During the End-to-End Analysis, systems comprising the PPB legacy enterprise were reviewed and as-is systems and business processes were modeled. Analysis of existing business processes, redundant capabilities, duplicated data, and the as-is enterprise architecture provided baseline information to allow formation of a new vision for the PPB BOS enterprise. Using this information, capabilities required to support the Army PPB BOS enterprise were identified. Using a services-oriented approach to architecture, business capabilities were instantiated as software services and served as the basic building blocks for the PPB BOS enterprise. PPB systems were transformed to the PPB BOS enterprise with the following assumptions. The assumptions were derived from a number of sources, including Army leadership, best practices, stated Army priorities and goals, and contractual statements. Those assumptions follow: • PPB BOS capabilities shall be delivered in manageable capability increments. • An …show more content…

• The PPB BOS shall interface with GFEBS. • The PPB BI/DW shall provide appropriate data-warehouse and analytical capabilities in support of the PPB BOS. • Efforts to stabilize the existing PPB environment in preparation for PPB BOS increments shall be performed. • The PPB BOS enterprise shall follow net-centric data sharing and transformation tenets as defined by OSD. From the bottom up, the implementation approach focused on providing detailed packages of information that helped guide development or migration of PPB BOS capabilities. The packages were named Capability Roadmap Packages (CRP) and were designed to provide a wide variety of information about a capability in one document. Some of the information contained in a CRP included high-level project information, initial requirements, architecture diagrams, placeholders for process metrics, and stakeholder contact
