They enable you to visualize the different types of roles in a system and how those roles interact with the system. This use case diagram tutorial will cover the following topics and help you create use cases better.  \n􀁸  Importance of use case diagrams  \n􀁸  Use case diagram objects  \n􀁸  Use case diagram guidelines  \n􀁸  Relationships in use case diagrams  \n􀁸  How to create use case diagrams ( with example )  \no  Identifying actors  \no  Identifying use cases  \no When to use “Include”  \no  How to use generalization  \no When to use “Extend”  \n􀁸  Use case diagram templates of common scenarios  \nImportance of Use Case Diagrams  \nAs mentioned before use case diagrams are used to gather a usage requirement of a system. Depending on your requirement you can use that data in different ways. Below are few ways to use them.  \n􀁸 To identify functions and how roles interact with them – The primary purpose of use case diagrams.  \n􀁸 For a high-level view of the system – Especially useful when presenting to managers or stakeholders. You can highlight the roles that interact with the system and the functionality provided by the system without going deep into inner workings of the system.  \n􀁸 To identify internal and external factors – This might sound simple but in large complex projects a system can be identified as an external role in another use case.  \nUse Case Diagram objects  \nUse case diagrams consist of 4 objects.  \n􀁸 Actor  \n􀁸 Use case  \n􀁸 System  \n􀁸 Package  \nThe objects are further explained below.  \nActor  \nActor in a use case diagram is any entity that performs a role in one given system. This could be a person, organization or an external system and usually drawn like skeleton shown below.  \nUse Case  \nA use case represents a function or an action within the system. It’s drawn as an oval and named with the function.  \nSystem  \nThe system is used to define the scope of the use case and drawn as a rectangle. This an optional element but useful when you’re visualizing large systems. For example, you can create all the use cases and then use the system object to define the scope covered by your project. Or you can even use it to show the different areas covered in different releases.  \nPackage  \nThe package is another optional element that is extremely useful in complex diagrams. Similar to class diagrams , packages are used to group together use cases. They are drawn like the image shown below.  \nUse Case Diagram Guidelines  \nAlthough use case diagrams can be used for various purposes there are some common guidelines you need to follow when drawing use cases.  \nThese include naming standards, directions of arrows, the placing of use cases, usage of system boxes and also proper usage of relationships.  \nWe’ve covered these guidelines in detail in a separate blog post. So go ahead and check out use case diagram guidelines.  \nRelationships in Use Case Diagrams  \nThere are five types of relationships in a use case diagram. They are  \n􀁸 Association between an actor and a use case  \n􀁸 Generalization of an actor  \n􀁸 Extend relationship between two use cases  \n􀁸 Include relationship between two use cases  \n􀁸 Generalization of a use case  \nWe have covered all these relationships in a separate blog post that has examples with images. We will not go into detail in this post but you can checkout relationships in use case diagrams.  \nHow to Create a Use Case Diagram  \nUp to now, you’ve learned about objects, relationships and guidelines that are critical when drawing use case diagrams. I’ll explain the  \nvarious processes using a banking system as an example.  \nIdentifying Actors  \nActors are external entities that interact with your system. It can be a person, another system or an organization. In a banking system, the most obvious actor is the customer. Other actors can be bank employee or cashie","cbCaisaowGg4r7l3","https://ap.wps.com/l/cbCaisaowGg4r7l3","pdf",804901,"English","# Importance of Use Case Diagrams\n# Use Case Diagram Objects\n## Actor\n## Use Case\n## System\n## Package\n# Use Case Diagram Guidelines\n# Relationships in Use Case Diagrams\n# How to Create a Use Case Diagram\n## Identifying Actors\n## Identifying Use Cases\n## When to Use \"Include\"\n## Generalization of Actors and Use Cases\n## When to Use \"Extend\"","[{\"question\":\"What is the main purpose of a use case diagram?\",\"answer\":\"A use case diagram gathers system usage requirements and shows how different roles interact with the system functions.\"},{\"question\":\"What four objects make up a use case diagram?\",\"answer\":\"The diagram consists of Actor, Use case, System (optional scope boundary), and Package (optional grouping for complex diagrams).\"},{\"question\":\"When should you use the «Include» and «Extend» relationships?\",\"answer\":\"Use «Include» for common functionality shared across multiple use cases and always invoked by the original use case.
