1. Information technology architecture what is it, why should you care, and how do you do one? Answer:- What is it? Briefly stated, an Information Technology (IT) Architecture is a blueprint that is developed, implemented, maintained, and used to explain and guide how an organization’s IT and information management elements work together to efficiently accomplish the mission of the organization. An IT Architecture addresses the following views: business activities and processes, data sets and information flows, applications and software, and technology. A proper Architecture is NOT limited to hardware and software issues. Having an IT Architecture with specific goals does not mean that an organization must immediately change all of its systems, etc. Part of an IT Architecture is a plan that addresses how the organization will migrate to the new targets over time. Why Should You Care? Responding to the dictates of good management as well as legislative requirements, the Department of Commerce requires that each of its Operating Units develop and implement one or more IT Architecture(s). An Operating Unit may have one IT Architecture that covers all of its offices and business processes, or a number of IT Architectures based on distinct business processes within the Operating Unit. Within NOAA, for example, the management of commercial fisheries could be considered one business process, while the issuance of nautical charts could be another. The Department may have a few basic requirements that all IT Architectures must contain, but aside from those, the specific contents of the Architecture are up to the Operating Unit. The best reasons for having an IT Architecture are the benefits it brings to your organization, and all DOC organizations who have implemented one have found it beneficial. Benefits have included the improved ability to share and efficiently process information, the ability to respond faster to changes in technology and business needs, and reductions in costs because of economies of scale and resource sharing. Oversight bodies, such as OMB and GAO, expect agencies to be developing and implementing Architectures. Failure to develop and implement an IT Architecture will adversely affect the chances of getting funding for new IT projects or improvements to current systems, as well as hinder an organization’s ability to meet customer needs efficiently (e.g., moves to electronic commerce). How Do You Do an IT Architecture? There are risks involved in doing an IT Architecture. In larger organizations it can become a time-consuming and potentially expensive task. To minimize the risks and maximize the benefits, you need to: have a defined process to follow, understand that process well, and make sure that the process fits your situation and needs. There is no one required process - you can find a number of different ones on the Web. They all have some things in common. When doing an IT Architecture you need to focus on:
