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.〔Chief Information Officer Council (2001). (A Practical Guide to Federal Enterprise Architecture )〕
== Overview ==
The enterprise life cycle is a key concept in enterprise architecture (EA), enterprise engineering〔Kosanke, Kurt, F. Vernadat, and Martin Zelm]. "CIMOSA: enterprise engineering and integration." ''Computers in industry'' 40.2 (1999): 83-97.〕 and systems engineering.〔Ronald E. Giachetti (2011) ''Design of Enterprise Systems: Theory, Architecture, and Methods.'' p. 7〕 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.〔Alain Bernard, Serge Tichkiewitch (2008). ''Methods and Tools for Effective Knowledge Life-Cycle-Management.'' p. 403〕
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.〔
