Vision Document

The vision document provides a complete vision for the software system under development and supports the contract between the funding authority and the development organization. Whether the project is a huge military-standard development (whose vision could be a 300-page system specification) or a small, internally funded commercial product (whose vision might be a two-page white paper), every project needs a source for capturing the expectations among stakeholders. A project vision is meant to be changeable as understanding evolves of the requirements, architecture, plans, and technology. A good vision document should change slowly. Figure 6-9 provides a default outline for a vision document.

The vision document is written from the user's perspective, focusing on the essential features of the system and acceptable levels of quality. The vision document should contain at least two appendixes. The first appendix should describe the operational concept using use cases (a visual model and a separate artifact). The second appendix should describe the change risks inherent in the vision statement, to guide defensive design efforts.

The vision statement should include a description of what will be included as well as those features considered but not included. It should also specify operational capacities (volumes, response times, accuracies), user profiles, and interoperational interfaces with entities outside the system boundary, where applicable. The vision should not be defined only for the initial operating level; its likely evolution path
