In information technology, architecture plays a major role in the aspects of business modernization, IT transformation, software development, as well as other major initiatives within the enterprise. IT architecture is used to implement an efficient, flexible, and high quality technology solution for a business problem, and is classified into three different categories: enterprise architecture, solution architecture and system architecture. Each of these classifications varies in their implementation and design, depending on the contextual business scope, organization structure, and corporate culture.
Architecture Level
Architecture level represents the scope boundary and granularity of details the architectural activity should take, based on organization hierarchy and communication audience.
- Enterprise Architecture (Company level) aligns technological strategies and execution plans with business visions and objectives by providing architectural oversight and guidance. Enterprise architecture also drives consolidation, reuse, and economy of scale by addressing company-wide goals in a holistic way across all IT projects.

Solution Architecture (Department level) models a solution vision that defines the IT systems, business processes and reusable services for a specific business unit, spanning across business and technology architectures.

System Architecture (Team level) defines the structure of an information system in terms of various subsystem components and their relationships with internal and external systems. System architecture focuses on application, data, and technology, and is called software architecture in some organizations.

- Total cost of ownership (TCO): System analyst must try to get solutions of different questions which helps in finding initial cost and cost which may add up during the development, which is total cost of ownership. This is most important at this will determine total cost and budget of system.
- Scalability: Determining system ability to expand or downsize according to business requirements.
- Security: What security system and policy needs to be implemented.
