In this post, we will define functional requirements that support these use cases. This process is an example of using structured requirements, applied to a small real world project.
Don’t do it. Don’t use a functional spec to get superficial agreements and navigate the beurocracy that accompanies large projects. Don’t validate the specification trivially.
