In this scenario, the cook is the actor, while the system would consist of the equipment, ingredients, and utensils. The goal is to be able to create sandwiches for customers during lunchtime. Creating a Use Cas

The core of a use case is itsmain success scenario– six to ten steps that describe how an actor gets something done. When written well, it gives a concise description of how the system needs to behave. When written poorly, it’s a tedious mess that makes the readers’ eyes glaze over...
