An agile enterprise is an organization that rapidly adapts to market and environmental changes in the most productive and cost-effective ways. To be agile, an enterprise should utilize the key principles of enterprise architecting enabled by the most recent developments in information and communication technologies and lean principles and. This paper describes a Lean Enterprise Architecture (LEA) to organize the activities for the transformation of the enterprise to agility. It is the application of systems architecting methods to design, develop, produce, construct, integrate, validate, and implement a lean enterprise using information engineering and systems engineering methods and practices. LEA is a comprehensive framework used to align an organization's information technology assets, people, operations, and projects with its operational characteristics. The architecture defines how information and technology support the business operations and provide benefit for its stakeholders.The architecting process incorporates lean attributes and values as design requirements in creating the enterprise. The application of the LEA is less resource intensive and disruptive to the organization than the traditional lean enterprise transformation methods and practices. Thus, it is essential that the merits of this process are re-marketed (communicated) to the stakeholders to encourage its acceptance.
