The purpose of IS/IT planning is to align the IT infrastructure with business goals. Planning, in general, determines what needs to be done (the objective), outlines the steps and the sequence of steps to accomplish the objective, and lists the time and effort needed to meet the objective. The following diagram displays how an IS/IT fits with other plans of an organization.
The result of a planning process is a document, a plan, which is a repository of information about the approach, the steps, the resources needed and the time frame for an effort. Within this general framework, several levels and types of planning exist in real life and enterprises. We all remember planning a vacation, planning a family relocation from one city to another, or planning a wedding. Our focus is on planning that transition strategies to working solutions. See a short tutorial on IT planning for a conceptual overview.
COMPUTER AIDED PLANNING: Planning of the IT infrastructure needed to support the emerging digital enterprises is a challenging task due to the numerous difficult decisions that have to be made quickly and correctly. Traditional IT planning that rely on largely manual activities are not adequate to meet the ever-changing demands of the digital enterprises. Although computer aided IT planning tools are needed, very few are commercially available. An exception is the PISA (Planning, Integration, Security & Administration) environment that uses ontologies, business patterns, best practices, and inferences to quickly recommend the IT infrastructure for the modern digital enterprises. Information about PISA can be found at the PISA website .
