Information Technology Planning is a discipline within the Information Technology and Information Systems domain and is concerned with making the planning process for information technology investments and decision-making a quicker, more flexible, and more thoroughly aligned process.〔Sharyn Leaver (2009), Tools For IT Planning, Forrester Research〕 According to Architecture & Governance Magazine, (Strategic) IT planning has become an overarching discipline within the Strategic Planning domain in which enterprise architecture is now one of several capabilities.〔The 2008 A&G Reader Survey: The Rise of Strategic IT Planning and Executive Involvement, Architecture & Governance Magazine〕 == Arguments for Information Technology Planning == IT takes too long to adjust plans to meet business needs. By the time IT is prepared, opportunities have passed and the plans are obsolete. IT doesn’t have the means to understand how it currently supports business strategy. The linkage between IT’s capabilities — and their associated costs, benefits, and risks — and business needs is not mapped out. Additionally, information gathering and number crunching hold the process back.〔 IT makes plans that don’t reflect what IT will actually do or what the business actually needs. In the end, business doesn’t understand how IT contributes to the execution of strategy. IT doesn’t start planning with a clear picture of which demand is truly strategic or which actions will have the biggest impact. Information regarding business needs and the costs, benefits, and risks of IT capabilities comes from sources of varying quality. IT then makes planning decisions based on misleading information.〔 IT’s plans often end up rigid and unverifiable. Plans don’t include contingencies that reduce the impact of change, nor have they been verified as the best plan of action via comparison to alternatives and scenarios. IT simply doesn’t have the time and information for it. Manually preparing multiple plans and selecting the best one would take too long for most organizations — especially considering the availability of the information needed for a comparison.〔 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 planning」の詳細全文を読む スポンサード リンク
