What are the components of information technology architecture?

ITA - Information Technology Architecture 

The ITA is a set of information technology principles, standards, guidelines, and statements of direction intended to facilitate and promote the design and purchase of interoperable systems. Appropriate architecture leads to savings in delivery time, price, training, support, and maintenance. The scope of the ITA is broad, extending from desktop computing software and hardware down through middleware, operating systems, and network protocols to voice, data and video hardware.

The notion of an ITA is relatively new, and the potential scope of an ITA is very large. The ITA should be documented on a internal WEB site The diagram in the attached document illustrates the structure of the WEB site. It also displays the fact that the ITA product (publications etc.) is created and maintained by a supporting process

Strategic Components are projects and activities with a three to five year time horizon that will substantially move the department in the direction of the strategies.

Projects arising from the Strategic Components will be subject to the same resource and budget pressures as other work in the department. From the Information Technology Branch perspective, this means that projects must be prioritized with the regular work objectives and other ideas proposed by staff. Since resources are finite, those activities will be cut which deliver the lowest value, whether they are currently done or only proposed. It is the intention of the Department to pursue corporate strategies, with the active support of all Branches.

The Logistical Components provided for each strategy are an additional resource, suggesting small projects or activities that could be undertaken for little cost and could be completed within six to nine months of their start. Work on these could create immediate momentum for change while the necessary planning is done to make the main Strategic Components viable.

Supporting the Strategic and Logistical Components are Key Player matrices. They suggest who should be involved in implementing the supporting components. The matrices analyze the various roles staff and management will need to play, such as sponsor, support, pilots, training, etc. The identification is by position, showing the inter-organizational nature of the strategies. These matrices should be used by project staff to involve all interested parties in the design and critique of solutions.

Frameworks are analytical devices for integrating the corporate strategies and components. Although the strategies can each be considered separately for implementation projects, they have a close relationship with each other. The Frameworks describe some of these relationships. For example, many components and strategies will mention networks, only a single, integrated network is intended, not multiple networks. Similarly, although education and training will be required to support each strategy and/or component, an integrated, multi-disciplinary education plan is more desirable than fragmented plans.

four components in an information architecture system:

• Organization systems are the categories in which we place information, such as author namesand titles or shoe size, fabric and color.
• Labeling systems are the ways we represent information, such as the level of terminology considered appropriate for the target audience. For example, should articles use the terms "optometrist" and "ophthalmologist," or is "eye doctor" more appropriate?
• Navigation systems are the way we move from one piece of information to another when that information is presented to us. On this page, for instance, you could use the Next button to get to the next page, or you could begin exploring something new at any time using the tabs like Adventure and Tech at the top of the page.
• Searching systems are the way we search for information, such as entering words in a search engine or scanning for terms in a numbered list. For example, in the search box on this page, you could type multiple words to narrow the results and get closer to the topics you want to read about.
