Publisher Summary This chapter focuses on research plan. A well-structured research plan is a communication tool that lets others in the company work with the schedule. It educates the colleagues about the benefits of user research and provides a forum for them to ask questions about their users and an expectation of the kind of knowledge the process can produce. A research plan consists of three major parts–why to do the research (the goals), when to do it (the schedule), and how much will it cost (the budget). These are in turn broken up into practical chunks such as report formats and timetables. Before writing a research plan, one should know two factors—the reason for the research, and how its results will be implemented. These two factors are considered together to figure out the questions that need to be addressed to have the most impact on the product. The first involves determining corporate priorities and setting research goals that can meet them. The second involves an understanding of the development process so that the research can make the greatest impact on the final product.
