10. Writing the Requirements
in which we turn the requirements into written form
Writing the requirements refers to the task of putting together a description of the product from the business point of view. Typically, this description is called a specification, and we use the term here to mean whatever description you are compiling, whether it is written or not. It is appropriate to think of this activity as building a specification: You assemble a specification, one requirement at a time, rather than writing it all at once.
