Every development project begin with a statement of the objectives it achieve. These clearly stated objectives form the requirements of the project. The development or re-engineering of a system must support these business objectives.
The initial scope of any project depends largely on whether an Information Strategy Plan already exists and is up to date. It may be useful to identify the main activity and data objects to confirm the scope and help to plan the analysis work even when planners have already established the scope of the development project.
It is common to begin analysis without the benefit of an information architecture that is derived from a strategic plan. The resulting systems must meet business needs, whether they are based on an enterprise-wide information architecture or not. Although analysts, planners, and coordinators may not achieve the full benefits of establishing a corporate information strategy, they can still reap significant rewards from a thorough analysis of the needs of part of the business. Their efforts additionally contribute to developing that architecture.
You can either perform or review some of the work that is typically done during planning to prepare for the analysis phase. This initial scoping, also named an Initial Needs Survey or Mini-ISP, ensures that the scope of analysis is set correctly.
The scaled-down versions of planning activities prove helpful. The analysis team can establish an initial set of subject areas and entity types, business functions, relevant current systems, and parts of the organization that is involved in this analysis effort.
In practice, management expectations often determine the scope of a project. A thorough analysis team outlines the information architecture early in the project. Creating this outline ensures that you have identified possible interactions with other areas, and that the scope does not encompass too much of the business.
A typical development project last from three to nine months. You can expect analysis to occupy about one quarter of this time.
