Use cases delve into the details on a single process, but that is not the only way to understand how a user might want to use an application. Employing user stories allows you to quickly brainstorm dozens of different tasks a user might want to accomplish. This helps during programming, as it guides you as you make functionality and interface decisions. Learn how to write quick and relevant user stories for your application by watching this online video.
There is another common format for writing description of parts of our application.…It's called a User Story.…Now a user story is simpler and shorter than a use case.…It still describes a single small scenario from a user's perspective focused on…their goal rather than on the system.…It's what do they want to do and why do they want to do it.…But unlike a use case, which could be several pages, a user story is typically…written as just one, perhaps two sentences, and they're very commonly written on index cards.…
And that forces us to keep them short and sweet, and that's kind of the point here.…But even though they are concise, user stories do generally follow a particular format.…And the format looks something like this.…"As a" -- type of user or role, "I want" -- here you describe the goal, "so that"…-- the reason or the benefit.…The final part, the "so that" is optional, but it's very useful.…So an example, as a bank customer I want to be able to change my pin online so…that I don't have to go into a branch.…
Let Simon Allardice introduce you to the terms—words like abstraction, inheritance, polymorphism, subclass—and guide you through defining your requirements and identifying use cases for your program. The course also covers creating conceptual models of your program with design patterns, class and sequence diagrams, and unified modeling language (UML) tools, and then shows how to convert the diagrams into code.
