The Three Pillars of IT Architecture
By Arijit Banerjee
IT architecture has been the key practice undertaken by an organization for achieving organization goals for decades. Many companies are brilliant at developing strategies but repeatedly see them come to nothing because they can’t cope with the multiple changes necessary to see them through.
When business structures need to change at the same time as new technology is being implemented and information processing is changing, it’s easy to become overwhelmed. IT architecture is designed to address this problem and IT architects are trained experts on finding robust solutions.
IT architecture, to be successful requires support from the organization and stands on the three pillars of IT architecture:
- Organizational policy: Organizational policy is a set of principles, rules, and guidelines formulated or adopted by an organization to reach its long-term goals. It is the main purpose of why the organization has been established. It is a premeditated rule set by a business to guide organizational direction, employees and business decisions, and to regulate, direct and control actions and conduct. It is the direct connection between the organization’s vision and its daily operation.
- IT strategy: For a better understanding of what is necessary to achieve the organizational goals and how and where the resources of the organization should be invested, IT strategy is one of the most important pillars of the IT architecture. It allows the IT architect to plan ahead according to the organizational need.
- Programs: Having a solid technical architecture in an organization is crucial for the success of the IT architecture, especially for a complex system and subsystems. For a solid technical architecture, the organization requires different software programs and technical tools like Telelogic system architect, Microsoft Office visio, casewise modeler, dragon1, powerpoint etc.
IT architecture heavily relies on the organizational policy as, without organizational rules, the IT architects won't know the goals they are trying to achieve. Enterprise Architects concern themselves with the strategic implementation of a company’s business goals. Every project the IT architects undertake is directed towards achieving the goals specified in the organizational policy. This makes the policy as the most important pillar for enterprise architecture management.
IT strategy provides the IT architecture with the opportunity to spread the cost over multiple budgets, rather than having to make the investment with a distressed need. This way the IT architect can carefully plan when and what to spend the IT budget on. This approach also supports suitable business growth, as it provides the organization with IT infrastructure that’s up to the job and can handle growth fluctuations better.
These programs allow an enterprise architect to take efficient and quick decisions as they can create models, viewpoints, views, and visualizations of the enterprise architecture for different stakeholders of an organization and generate various reports on it.
Programs are the actual tools and softwares that get the work done in an organization and allows the IT architect to find solutions by completing different projects and reports to link the current state of the organization to its future state thus, achieving organization goals.
