Learn in the textbookValidation, Acceptance, and Migration
DefinitionA user manual (利用者マニュアル) is a document of operating procedures that people who use the system consult in their daily work.
ExplanationIts readers are the people who use the system rather than developers, so it describes steps that follow screen operations and the flow of work, not the inner design. It is prepared during the acceptance stage and also serves as material for educating and training users.
AnalogyIt is like the step-by-step sheets a shop prepares for new staff, one for each task such as ringing up sales or handling returns.
Memory hookThe word user at the front of the name tells you who reads it; a design document, read by the builders, has a different reader from the start.
