IT management is the discipline whereby all of the information technology resources of a firm are managed in accordance with its needs and priorities. These resources may include tangible investments like computer hardware, software, data, networks and data centre facilities, as well as the staff who are hired to maintain them. Managing this responsibility within a company entails many of the basic management functions, like budgeting, staffing, change management, and organizing and controlling, along with other aspects that are unique to technology, like software design, network planning, tech support etc. ==Overview== The central aim of IT management is to generate value through the use of technology. To achieve this, business strategies and technology must be aligned. IT Management is different from management information systems. The latter refers to management methods tied to the automation or support of human decision making. IT Management refers to IT related management activities in organizations. MIS is focused mainly on the business aspect, with strong input into the technology phase of the business/organization. A primary focus of IT management is the value creation made possible by technology. This requires the alignment of technology and business strategies. While the value creation for an organization involves a network of relationships between internal and external environments, technology plays an important role in improving the overall value chain of an organization. However, this increase requires business and technology management to work as a creative, synergistic, and collaborative team instead of a purely mechanistic span of control.〔Bird, M. (2010). Modern Management Guide to Information Technology. Create Space.〕 Historically, one set of resources was dedicated to one particular computing technology, business application or line of business, and managed in a silo-like fashion.〔(Talbot, Chris, “HP Adds to Converged Infrastructure Lineup,” ChannelInsider, June 7, 2011. )〕 These resources supported a single set of requirements and processes, and couldn’t easily be optimized or reconfigured to support actual demand.〔(Gardner, Dana, "Converged Infrastructure Approach Paves Way for Improved Data Center Productivity, Private Clouds,” February 9, 2010, IT Business Edge )〕 This led technology providers to build out and complement their product-centric infrastructure and management offerings with Converged Infrastructure environments that converge servers, storage, networking, security, management and facilities.〔(Huff, Lisa, “The Battle for the Converged Data Center Network,” Data Center Knowledge, August 18, 2011. )〕〔(Harris, Derrick, "Can Open Converged Infrastructure Compete?" GigaOM, October 10, 2010. )〕 The efficiencies of having this type of integrated and automated management environment allows enterprises to get their applications up and running faster, with simpler manageability and maintenance, and enables IT to adjust IT resources (such as servers, storage and networking) quicker to meet unpredictable business demand.〔(Oestreich, Ken, "Converged Infrastructure," CTO Forum, November 15, 2010. )〕〔(Golden, Bernard, "Cloud Computing: Two Kinds of Agility," CIO, July 16, 2010. )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Information technology management」の詳細全文を読む スポンサード リンク
