Basically, the concept of "use cases" is an important foundation in modern software development. The term is often used in the tech industry to describe the way a user will interact with a system or application in a real situation.
So, what is the meaning, function and examples of applying use cases in software development?
Definition of use case
A use case is a description of a scenario or situation that explains how a user will use a system or application to achieve a specific goal. In the context of software development, use cases help in detailing how a feature or function should work from the user's perspective.
Use cases can be workflows, interaction steps, or other usage scenarios that describe in detail what is expected from the software.
Function of use case
The following are several use case functions in software development.
1. Detailing user needs
One of the main functions of a use case is to specify user needs. By exploring various usage scenarios, development teams can better understand what users want from the software being developed.
2. Describes the functionality of the software
Use cases help in describing the functionality of the software from the user's perspective. That way, the development team can understand how the software should behave in various situations and determine which features should be included.
3. Guide to development and testing
Use cases also serve as a guide for the development team in the software development and testing process. By using use cases as a reference, teams can identify the steps required to implement and test each feature or function.
4. Communication with stakeholders
Use cases help in facilitating communication between the development team and other stakeholders, such as clients or management. By using use cases as a communication tool, all parties involved can have a common understanding of how the software will be used and what to expect.

Examples of using use case in software development
The following are examples of using use cases in software development.
1. E-commerce Application
Use case: A user wants to buy a product through an e-commerce application.
- User opens an e-commerce application.
- Users search for the desired product.
- Users select products and add them to the shopping cart.
- Users make payments using the desired method.
- The system confirms the payment and sends a notification to the user.
2. Project Management System
Use case: A project manager wants to assign tasks to his team members.
- The project manager logs in to the project management system.
- The project manager creates a new task and defines its details.
- The project manager assigns tasks to the relevant team members.
- Team members receive notifications about assigned tasks.
- Team members complete tasks and notify the project manager.
3. Social Media Applications
Use case: A user wants to share a photo with his friends.
- User opens a social media application;.
- The user selects the option to share the photo.
- Users select the photos they want to share.
- Users add text or captions if desired.
- The user selects the friends with whom he wants to share the photo.
- The system posts photos to the user's profile and notifies his friends.
From the explanation above, it can be seen that use cases are very important in software development as they help in detailing user requirements, describe software functionality, guide the development and testing process, and facilitate communication with stakeholders.
By using use cases effectively, development teams can produce software that meets user needs and meets desired business goals.
