82 Part II Software Requirements Development The owner of the vision and scope document is the project's executive sponsor, funding authority, or someone in a similar role. A requirements analyst can work with the owner to write the vision and scope document. Input on the business requirements should come from individuals who have a clear sense of why they are undertaking the project. These individuals might include the customer or development organization's senior management, a project visionary, a product manager, a subject matter expert, or members of the markering department. Figure 5-2 suggests a template for a vision and scope document. Document templates standardize the structure of the documents created by your organization's project teams. As with any template, adapt this one to meet the specifk needs of your own projects. 1.

Business Context 4.1 Stakeholder Profiles 4.2 Project Priorities 4.3 Operating Environment Figure 5-2 Template for vision and scope document. Parts of the vision and scope document might seem repetitive, but they should interlock in a sensible way. Consider the following example: Business Opportunity Exploit the poor security record of a competing product. Business Objective Capture a market share of 80 percent by being recognized as the most secure product in the market through trade journal reviews and consumer surveys.

Derermine how the Stakeholders will define and measure success on this project (Wiegers 2002c).
