be undertaken to implement each of the strategies. Major steps in this phase and corresponding activities are described below. Identify and specify projects: In this step, each strategy is broken into specific projects — to facilitate control, implementation and matching to the resource capability of the anization. Also, the projects may need to be integrated to business related projects such as business reengineering. These projects include any transitional projects that are required as a bridge between the new and existing information systems. Key activities include: ? specifying the nature, functionality, and scope of each project。 ? establishing interdependencies between projects。 ? identifying the costs and benefits of individual projects。 and ? estimating the implementation timeframe for each project. At the end of this step, all the projects required to support the implementation of the strategic plan will have been specified. Prioritize projects: The strategic plan provides only broad guidance on the priorities of the projects. Now that the projects are specified, their priorities must be confirmed. Criteria to consider include: ? strategic impact of the project in supporting the business strategy。 ? dependencies on other projects — for example, a munication work may be the foundation project for a new service delivery offering and would need to be scheduled and pleted prior to the new service delivery offering。 ? business imperatives — for example, the launch date of a new product or changes to regulatory requirements or meeting petitive or customer needs。 ? benefits that can be realized — projects with high benefits or quick results should be fasttracked。 and ? resource requirements — for example, funding may constrain the concurrent implementation of major projects. At the end of this step all the projects in the tactical plan will have been prioritized. Develop the tactical plan: In this step, each project is scheduled for implementation based on its priority, the resources required, the resources available and the implementation timeframe. The implementation plan should: ? schedule all projects, specifying who does what and when。 ? identify the critical path and performance milestones for key deliverables。 ? provide the underlying assumptions and constraints。 and ? develop financial, resource allocation, and benefit realization plans to support the implementation of the projects. At the end of this activity, the anization will have formulated a plan for translating the strategy into actions. Remend monitoring and control process: In this concluding step, the monitoring and control mechanisms need to be established to ensure that the plan is implemented in a timely, efficient, and effective manner. Typically, the overall responsibility for the continuing approval and oversight of the plan rests with an executive level mittee — the Information Technology Steering Committee. Key activities include: ? developing a monitoring and control mechanism that will ensure that the plan implementation as well as business and information technology assumptions are periodically reviewed and, where appropriate, corrective action is taken。 ? assigning accountabilities for the implementation of specific projects within the plan — for example, a project sponsor and project manager。 and ? assigning responsibilities for delivering estimated benefits from those parts of the information technology plan that have been implemented — for example, the senior business executives responsible for areas where the new or enhanced system is being used. This step marks the conclusion of the information technology planning process.
