Use Case Diagram Example – Something That Must Be Learned

If you are sailing on the internet searching for some helping material on business analyst profession, the interview questions and scope of the profession, you must be prepared to excel in building use case diagrams. Use case diagram is one of the most common techniques used by business analysts when managing a particular project. It is very much possible that your interviewer will ask you to draw a use case diagram example in the interview. Of course, you will draw a very simple and basic diagram of a very basic system because the main purpose of this test is to check your knowledge of use case diagram.

Even if you are a newbie who takes interest in this particular profession and wants to be a successful business analyst in future, you should start learning about the various UML methods used by business analysts because they are the most important part of any business analyst’s working. Use case diagram is vital to this profession and it is not even a very complex diagram as compared to other types of diagrams e.g. a flowchart of a complex process. When a project is just starting the use case diagram plays a vital role in many ways.

When you draw a use case diagram you are actually drawing the system and people who are part of the system. You will draw the actors who interact with the system along with their use cases meaning the various ways they interact with the system. Think about an HR department in a company and how different employees interact with the department. The use case diagram will illustrate how different people touch the system and what purpose do they want served when they approach a particular system. Furthermore, you see on the diagram how system responds to their queries.

So for example, you want to create an attendance management system for a company and you have been given the project to be completed within a timeline. The first thing you will have to do is know the complete system and the various roles (actors) that come in contact with the attendance management system. This will give you the basic requirements for your system to be called a complete system and the requirements of various actors from the system. Eventually, your system must be complete to deliver the required results without skipping any vital role from it.

A business analyst would be required to give a use case diagram example in the interview because it is vital to a complete project management process. Think of the system in a restaurant for placing the order and actors involved in placing, taking and furnishing the ordered food. The actors in a restaurant would be the customer, the waiter, cashier and the chef cooking the food. The interaction between them and the system when shown in the form of a diagram will be the use case diagram. This must be remembered that the sequence of the process or a logical end of it is not what a use case diagram is supposed to depict.
