Information technology planning can be described as a continuous cyclical process composed of three phases whose primary purpose is optimum allocation of scarce resources. In the assessment phase, planners assess user needs, environmental factors, business objectives, and IT infrastructure needs to develop IT projects that address needs in each of these areas. A major goal of this phase is to develop a broad IT inventory. The prioritization phase seeks to ensure optimum allocation of scarce resources by prioritizing ITprojects based on: Costs--total life cycle costs. Benefits--both quantitative and non-quantitative, including support for the organization's strategic business objectives. Risks--subjective assessments of technological and non-technological risks. Implementation requirements--time and personnel requirements to implement the system. The scheduling phase incorporates sequencing considerations, personnel availability, and budgetary constraints to produce an IT plan in which project priorities are adjusted to meet organizational realities.
信息技术规划可被描述为一个由三个阶段组成的持续循环过程，其主要目的是对稀缺资源进行优化配置。在评估阶段，规划者评估用户需求、环境因素、业务目标以及信息技术基础设施需求，以开发能够满足这些领域各自需求的信息技术项目。此阶段的一个主要目标是编制一份全面的信息技术清单。优先级确定阶段旨在通过基于以下因素对信息技术项目进行优先级排序，以确保对稀缺资源的优化配置：成本——整个生命周期成本；效益——包括定量和非定量效益，其中非定量效益包括对组织战略业务目标的支持；风险——对技术和非技术风险的主观评估；实施要求——实施系统所需的时间和人员要求。调度阶段纳入了顺序考虑、人员可用性和预算限制，以制定一份信息技术计划，在该计划中，项目优先级会进行调整以适应组织实际情况。
