Enterprise Architecture (EA) is the process of planning and arranging the activities and structure of a complete business. Business processes, information flows, technological infrastructure, and human resources are just a few of the many facets it includes. Aligning an organization's activities with its business goals and objectives is the aim of enterprise architecture. TCS uses enterprise architecture to optimize processes, make well-informed decisions about technology investments, and make sure that all of the organization's many parts function well together to meet its strategic goals. For major companies like TCS, maintaining agility, innovation, and competitiveness in the quickly changing technology landscape is an essential discipline.
