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 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 an 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.
