Illustration of the Enterprise Life Cycle.[1]

El Ciclo de Vida Empresarial (ELC) en la Arquitectura de la Empresa es el dinámico e iterativoproceso de cambio en una empresa a través del tiempo mediante la incorporación de nuevos procesos de negocioes, nueva tecnología, y nuevas capacidades, al igual que mantenimiento, la disposición y disponibilidad de elementos existentes en la empresa.[1]

Overview

El ciclo de vida empresarial es un concepto clave en la Arquitectura Empresarial (EA), Ingeniería de la Empresa[2] e Ingeniería de Sistemas.[3] El proceso de Arquitectura Empresarial esta estrechamente relacionado con procesos similares, como el ciclo de Sistemas de Gestión o el Sistema de Ciclo de Desarrollo de Vida, y tiene propiedades similares a las que podemos encontrar en el Ciclo de Vida del Producto.[4]

El concepto de Ciclo de Vida Empresarial ayuda en la implementación de la Arquitectura Empresarial, y el Control de la Planificación de Capital e Inversión (CPIC) procesos que seleccionan, controlan, y evalúan inversiones. Sobre estos procesos están la Gestión de Capital Humano y elManejo de Seguridad Informática.Cuando estos procesos trabajan juntos de manera efectiva, la empresa puede gestionar de manera efectiva tecnología de la información como un recurso estratégico y facilitador de procesos de negocio. Cuando estos procesos son correctamente Sincronizados, los sistemas migran de manera eficiente del legado de entornos tecnológicos a través de desarrollos evolutivos e incrementales, y la empresa se vuelve capaz de demostrar su Retorno de Inversión (ROI). La figura en la parte superior ilustra la interacción de ciclos dinámicos e interactivos que se producirán con el tiempo.[1]

Enterprise life cycle topics

Enterprise architecture process

Enterprise Architecture Process.[1]

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.[1]

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.[1]

Architecture life cycle

DoDAF Architecture Life Cycle.[5]

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.[5]

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.[5]

Enterprise life cycle activities

TEAF Enterprise Life Cycle activities[6]

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).[6]

The enterprise life cycle applies to enterprise-wide planning activities and decision making. By contrast, a System Development Life Cycle generally refers to practices for building individual systems. Determining what systems to build is an enterprise-level decision.[6]

The figure on the right depicts notional activities of an enterprise life cycle methodology. Within the context of this document, Enterprise Life Cycle does not refer to a specific methodology or a specific bureau's approach. Each organization needs to follow a documented Enterprise Life Cycle methodology appropriate to its size, the complexity of its enterprise, and the scope of its needs.[6]

Enterprise Performance Life Cycle

Illustration of the Enterprise Performance Life Cycle of the U.S. Department of Health & Human Services.[7]

The Enterprise Performance Life Cycle (EPLC) encompasses the major business functions executed under the Office of the Chief Information Officer (CIO), and in particular shows at a high level the relationship among the different business functions and both the general order and the iterative nature of their execution. The placement of enterprise architecture in the center of the EPLC conceptual diagram, shown in the figure, reflects the supporting and enabling role that enterprise architecture serves for the major business functions in the Enterprise Performance Life Cycle.[7]

The Enterprise Architecture (EA) Program explicitly considers the information needs of the Enterprise Performance Life Cycle (EPLC) processes in developing and enhancing the EA Framework, collecting and populating data in the EA Repository, and developing views, reports, and analytical tools that can be used to facilitate the execution of the EPLC processes. The EPLC conceptual diagram in the figure provides a Departmental perspective of key business functions. The EPLC is also relevant from an individual investment or project perspective, as each new investment passes through each phase of the EPLC. The investment-level perspective is detailed in the Enterprise Performance Life Cycle Framework.[7]
