Enterprise life cycle
Enterprise life cycle (ELC) in enterprise architecture is the dynamic, iterative process of changing the enterprise over time by incorporating new business processes, new technology, and new capabilities, as well as maintenance, disposition and disposal of existing elements of the enterprise.
The enterprise life cycle is a key concept in enterprise architecture (EA), enterprise engineering and systems engineering. The Enterprise Architecture process is closely related to similar processes, as program management cycle or systems development life cycle, and has similar properties to those found in the product life cycle.
The concept of enterprise life cycle aids in the implementation of enterprise architecture, and the capital planning and investment control (CPIC) process that selects, controls, and evaluates investments. Overlying these processes are human capital management and information security management. When these processes work together effectively, the enterprise can effectively manage information technology as a strategic resource and business process enabler. When these processes are properly synchronized, systems migrate efficiently from legacy technology environments through evolutionary and incremental developments, and the Agency is able to demonstrate its return on investment (ROI). The figure on top illustrates the interaction of the dynamic and interactive cycles as they would occur over time.
As a prerequisite to the development of every enterprise architecture, each Agency should establish the need to develop an EA and formulate a strategy that includes the definition of a vision, objectives, and principles. The figure shows a representation of the EA process. Executive buy-in and support should be established and an architectural team created within the organization. The team defines an approach and process tailored to Agency needs. The architecture team implements the process to build both the baseline and target EAs.
The architecture team also generates a sequencing plan for the transition of systems, applications, and associated business practices predicated upon a detailed gap analysis. The architecture is employed in the CPIC and the enterprise engineering and program management processes via prioritized, incremental projects and the insertion of emerging new technologies. Lastly, the architectures are maintained through a continuous modification to reflect the Agency's current baseline and target business practices, organizational goals, visions, technology, and infrastructure.
The figure depicts the life of the architecture as it evolves and shows the process that the architecture description supports in the development, analysis, and evolution of the implemented architecture. In this illustration, the Operational View is used to drive the requirements that are evaluated against the Systems View. Operational deficiencies are derived from the analysis, and viable candidates are identified. These candidates can take the form of either materiel or non- materiel solutions and are modeled back into the Operational and Systems Views of the architecture.
The architecture is re-analyzed, and the process continues until the operational deficiencies are minimized. The final sets of viable candidates are assessed for operational viability. Based on the results of the assessments, design changes are made and submitted for inclusion into the budgeting process. This process of developing, analyzing, and modifying continues throughout the architecture's life cycle.
An enterprise life cycle integrates the management, business, and engineering life cycle processes that span the enterprise to align its business and IT activities. Enterprise life cycle refers generally to an organization's approach for managing activities and making decisions during ongoing refreshment of business and technical practices to support its enterprise mission. These activities include investment management, project definition, configuration management, accountability, and guidance for systems development according to a system development life cycle (SDLC).
