What is Use Case Modeling?

This is a technique used in software development and systems engineering to describe the functional requirements of a system. It focuses on understanding and documenting how a system is supposed to work from the perspective of the end users. In essence, it helps answer the question: “What should the system do to meet the needs and goals of its users?”

What is Use Case Diagram?

Key Concepts of Use Case Modeling

Functional Requirements : Functional requirements are the features, actions, and behaviors a system must have to fulfill its intended purpose. Use case modeling is primarily concerned with defining and capturing these requirements in a structured manner.

End User’s Perspective : Use case modeling starts by looking at the system from the viewpoint of the people or entities (referred to as “actors”) who will interact with the system. It’s essential to understand how these actors will use the system to achieve their objectives or perform their tasks.

Interactions : Use case modeling emphasizes capturing the interactions between these end users (actors) and the system. It’s not just about what the system does in isolation; it’s about how it responds to user actions or requests.

The Basics of Use Cases:

  • A use case is a description of how a system interacts with one or more external entities, called actors, to achieve a specific goal.
  • A use case can be written in textual or diagrammatic form, depending on the level of detail and complexity required.
  • A use case should capture the essential and relevant aspects of the interaction, such as the preconditions, postconditions, main flow, alternative flows, and exceptions.

What is a Use Case Diagram?

A use case diagram is a graphical representation used in use case modeling to visualize and communicate these interactions and relationships. In a use case diagram, you’ll typically see actors represented as stick figures, and the use cases (specific functionalities or features) as ovals or rectangles. Lines and arrows connect the actors to the use cases, showing how they interact.

  • Actors : These are the entities or users outside the system who interact with it. They can be people, other systems, or even external hardware devices. Each actor has specific roles or responsibilities within the system.
  • Use Cases : Use cases represent specific functionalities or processes that the system can perform to meet the needs of the actors. Each use case typically has a name and a description, which helps in understanding what it accomplishes.
  • Relationships : The lines and arrows connecting actors and use cases in the diagram depict how the actors interact with the system through these use cases. Different types of relationships, such as associations, extend relationships, and include relationships, can be used to specify the nature of these interactions.

How to Perform Use Case Modeling?

  • To understand a use case, you need to identify the actors and the use cases involved in the system. An actor is an external entity that has a role in the interaction with the system. An actor can be a person, another system, or a time event.
  • A use case is a set of scenarios that describe how the system and the actor collaborate to achieve a common goal1. A scenario is a sequence of steps that describe what happens in a specific situation1. Actors in Use Case Modeling:
  • Actors are represented by stick figures in a Use Case diagram. Actors can have generalization relationships, which indicate that one actor inherits the characteristics and behaviors of another actor. For example, a Student actor can be a generalization of an Undergraduate Student actor and a Graduate Student actor.
  • Actors can also have association relationships, which indicate that an actor is involved in a use case. For example, an Instructor actor can be associated with a Grade Assignment use case.

Relationships Between Actors and Use Cases:

Use Case Diagram - Website _ Structuring use cases with extend and ...

  • An include relationship is a dependency between two use cases, where one use case (the base) incorporates the behavior of another use case (the inclusion) as part of its normal execution.
  • An include relationship is represented by a dashed arrow with the stereotype «include» from the base to the inclusion.
  • An include relationship can be used to reuse common functionality, simplify complex use cases, or abstract low-level details
  • An extend relationship is a dependency between two use cases, where one use case (the extension) adds some optional or exceptional behavior to another use case (the base) under certain conditions.
  • An extend relationship is represented by a dashed arrow with the stereotype «extend» from the extension to the base.
  • An extend relationship can have an extension point, which is a location in the base use case where the extension can be inserted.
  • An extension point can be labeled with a name and a condition

Creating Effective Use Cases:

  • A system boundary is a box that encloses the use cases and shows the scope of the system.
  • A system boundary helps to distinguish what is inside the system (the use cases) and what is outside the system (the actors).
  • A system boundary should be clearly labeled with the name of the system and its version1.
  • A use case goal is a statement that summarizes what the use case accomplishes for the actor.
  • A use case goal should be specific, measurable, achievable, relevant, and testable.
  • A use case scenario is a sequence of steps that describes how the actor and the system interact to achieve the goal.
  • A use case scenario should be complete, consistent, realistic, and traceable.
  • A use case description is a textual document that provides more details about the use case, such as the preconditions, postconditions, main flow, alternative flows, and exceptions.
  • A use case description should be clear and concise, using simple and precise language, avoiding jargon and ambiguity, and following a consistent format.
  • A use case description should also be coherent and comprehensive, covering all possible scenarios, outcomes, and variations, and addressing all relevant requirements.
  • A use case template is a standardized format that helps to organize and present the use case information in a consistent and structured way.
  • A use case template can include various sections, such as the use case name, ID, goal, actors, priority, assumptions, preconditions, postconditions, main flow, alternative flows, exceptions, etc.
  • A use case documentation is a collection of use cases that describes the functionality of the system from different perspectives.
  • A use case documentation can be used for various purposes, such as communication, validation, verification, testing, maintenance, etc.

Use Case Modeling Best Practices:

  • Identify the  key stakeholders  and their goals, and involve them in the use case development process
  • Use a  top-down  approach to identify and prioritize the most important use cases
  • Use a  naming convention  that is consistent, meaningful, and descriptive for the use cases and actors
  • Use  diagrams  and  textual descriptions  to complement each other and provide different levels of detail
  • Use  relationships  such as extend, include, and generalization to show dependencies and commonalities among use cases
  • Review and  validate  the use cases with the stakeholders and ensure that they are aligned with the system requirements

Use Case Modeling using Use Case Template

Problem description: university library system.

The University Library System is facing a range of operational challenges that impact its efficiency and the quality of service it provides to students, faculty, and staff. These challenges include:

  • Manual Borrowing and Return Processes : The library relies on paper-based processes for book borrowing, return, and tracking of due dates. This manual approach is prone to errors, leading to discrepancies in record-keeping and occasional disputes between library staff and users.
  • Inventory Management : The current system for managing the library’s extensive collection of books and materials is outdated. The lack of an efficient inventory management system makes it difficult to locate specific items, leading to frustration among library patrons and unnecessary delays.
  • Late Fee Tracking : Tracking and collecting late fees for overdue books are challenging tasks. The library staff lacks an automated system to monitor due dates and assess fines accurately. This results in a loss of revenue and inconvenience for users.
  • User Account Management : User accounts, including library card issuance and management, rely on manual processes. This leads to delays in providing access to library resources for new students and difficulties in updating user information for existing members.
  • Limited Accessibility : The current library system lacks online access for users to search for books, place holds, or renew checked-out items remotely. This limitation hinders the convenience and accessibility that modern students and faculty expect.
  • Inefficient Resource Allocation : The library staff often face challenges in optimizing the allocation of resources, such as books, journals, and study spaces. The lack of real-time data and analytics makes it difficult to make informed decisions about resource distribution.
  • Communication Gaps : There is a communication gap between library staff and users. Users are often unaware of library policies, new arrivals, or changes in operating hours, leading to misunderstandings and frustration.
  • Security Concerns : The library system lacks adequate security measures to protect user data and prevent theft or unauthorized access to library resources.

These challenges collectively contribute to a suboptimal library experience for both library staff and users. Addressing these issues and modernizing the University Library System is essential to provide efficient services, enhance user satisfaction, and improve the overall academic experience within the university community.

Granularity of Use Cases

Use Case Granularity Definition : Use case granularity refers to the degree of detail and organization within use case specifications. It essentially describes how finely you break down the functionality of a system when documenting use cases. In simpler terms, it’s about how much or how little you decompose a use case into smaller parts or steps.

Importance of Use Case Granularity :

  • Communication Enhancement : Use case granularity plays a crucial role in improving communication between different stakeholders involved in a software project, such as business analysts, developers, testers, and end-users. When use cases are well-defined and appropriately granulated, everyone can better understand the system’s functionality and requirements.
  • Project Planning : The level of granularity in use cases impacts project planning. Smaller, more finely grained use cases can make it easier to estimate the time and effort required for development tasks. This aids project managers in creating more accurate project schedules and resource allocation.
  • Clarity and Precision : Achieving the right level of granularity ensures that use cases are clear and precise. If use cases are too high-level and abstract, they might lack the necessary detail for effective development. Conversely, overly detailed use cases can become unwieldy and difficult to manage.

Example : Let’s illustrate use case granularity with an example related to a “User Registration” functionality in an e-commerce application:

  • High Granularity : A single use case titled “User Registration” covers the entire registration process from start to finish. It includes every step, such as entering personal information, creating a password, confirming the password, and submitting the registration form.
  • Medium Granularity : Use cases are divided into smaller, more focused parts. For instance, “Enter Personal Information,” “Create Password,” and “Submit Registration” could be separate use cases. Each of these focuses on a specific aspect of user registration.
  • Low Granularity : The lowest level of granularity might involve breaking down actions within a single step. For example, “Enter Personal Information” could further decompose into “Enter First Name,” “Enter Last Name,” “Enter Email Address,” and so on.

The appropriate level of granularity depends on project requirements and the specific needs of stakeholders. Finding the right balance is essential to ensure that use cases are understandable, manageable, and effective in conveying system functionality to all involved parties.

In his book ‘Writing Effective Use Cases,’ Alastair Cockburn provides a simple analogy to help us visualize various levels of goal attainment. He suggests thinking about these levels using the analogy of the sea

1. What is a Use Case Diagram in UML?

A Use Case Diagram is a type of Unified Modeling Language (UML) diagram that represents the interaction between actors (users or external systems) and a system under consideration to accomplish specific goals. It provides a high-level view of the system’s functionality by illustrating the various ways users can interact with it.

Use-Case-Diagram-Notations

2. Use Case Diagram Notations

UML notations provide a visual language that enables software developers, designers, and other stakeholders to communicate and document system designs, architectures, and behaviors in a consistent and understandable manner.

1.1. Actors

Actors are external entities that interact with the system. These can include users, other systems, or hardware devices. In the context of a Use Case Diagram, actors initiate use cases and receive the outcomes. Proper identification and understanding of actors are crucial for accurately modeling system behavior.

Actor-(1)

1.2. Use Cases

Use cases are like scenes in the play. They represent specific things your system can do. In the online shopping system, examples of use cases could be “Place Order,” “Track Delivery,” or “Update Product Information”. Use cases are represented by ovals.

Use-Case-

1.3. System Boundary

The system boundary is a visual representation of the scope or limits of the system you are modeling. It defines what is inside the system and what is outside. The boundary helps to establish a clear distinction between the elements that are part of the system and those that are external to it. The system boundary is typically represented by a rectangular box that surrounds all the use cases of the system.

Purpose of System Boundary:

  • Scope Definition: It clearly outlines the boundaries of the system, indicating which components are internal to the system and which are external actors or entities interacting with the system.
  • Focus on Relevance: By delineating the system’s scope, the diagram can focus on illustrating the essential functionalities provided by the system without unnecessary details about external entities.

3. Use Case Diagram Relationships

In a Use Case Diagram, relationships play a crucial role in depicting the interactions between actors and use cases. These relationships provide a comprehensive view of the system’s functionality and its various scenarios. Let’s delve into the key types of relationships and explore examples to illustrate their usage.

3.1. Association Relationship

The Association Relationship represents a communication or interaction between an actor and a use case. It is depicted by a line connecting the actor to the use case. This relationship signifies that the actor is involved in the functionality described by the use case.

Example: Online Banking System

  • Actor: Customer
  • Use Case: Transfer Funds
  • Association: A line connecting the “Customer” actor to the “Transfer Funds” use case, indicating the customer’s involvement in the funds transfer process.

Association-(1)

3.2. Include Relationship

The Include Relationship indicates that a use case includes the functionality of another use case. It is denoted by a dashed arrow pointing from the including use case to the included use case. This relationship promotes modular and reusable design.

Example: Social Media Posting

  • Use Cases: Compose Post, Add Image
  • Include Relationship: The “Compose Post” use case includes the functionality of “Add Image.” Therefore, composing a post includes the action of adding an image.

Include

3.3. Extend Relationship

The Extend Relationship illustrates that a use case can be extended by another use case under specific conditions. It is represented by a dashed arrow with the keyword “extend.” This relationship is useful for handling optional or exceptional behavior.

Example: Flight Booking System

  • Use Cases: Book Flight, Select Seat
  • Extend Relationship: The “Select Seat” use case may extend the “Book Flight” use case when the user wants to choose a specific seat, but it is an optional step.

Extend

3.4. Generalization Relationship

The Generalization Relationship establishes an “is-a” connection between two use cases, indicating that one use case is a specialized version of another. It is represented by an arrow pointing from the specialized use case to the general use case.

Example: Vehicle Rental System

  • Use Cases: Rent Car, Rent Bike
  • Generalization Relationship: Both “Rent Car” and “Rent Bike” are specialized versions of the general use case “Rent Vehicle.”

Generalization

4. How to draw a Use Case diagram in UML?

Step 1: identify actors.

Determine who or what interacts with the system. These are your actors. They can be users, other systems, or external entities.

Step 2: Identify Use Cases

Identify the main functionalities or actions the system must perform. These are your use cases. Each use case should represent a specific piece of functionality.

Step 3: Connect Actors and Use Cases

Draw lines (associations) between actors and the use cases they are involved in. This represents the interactions between actors and the system.

Step 4: Add System Boundary

Draw a box around the actors and use cases to represent the system boundary. This defines the scope of your system.

Step 5: Define Relationships

If certain use cases are related or if one use case is an extension of another, you can indicate these relationships with appropriate notations.

Step 6: Review and Refine

Step back and review your diagram. Ensure that it accurately represents the interactions and relationships in your system. Refine as needed.

Step 7: Validate

Share your use case diagram with stakeholders and gather feedback. Ensure that it aligns with their understanding of the system’s functionality.

Let’s understand how to draw a Use Case diagram with the help of an Online Shopping System:

Everything You Need to Know About Use Case Diagrams

By Jennifer Gaskin , Nov 16, 2021

use case diagram

Organizations that regularly interact with their customers need to have ways of visualizing those processes and describing how exactly the interaction should go. Borrowing from the software programming industry, building a use case diagram is an excellent way to do this.

Let’s explore what you need to know about use case diagrams and how they can help keep everything straight in your company’s systems and processes, then start creating one using Venngage Use Case Diagram Maker .

Click to jump ahead:

What is a use case diagram, what is a use case diagram used for, what are the 4 main components of a use case diagram, how do you create a use case diagram, use case diagram examples.

  • Use case diagram FAQs

Use case diagrams visualize the interactions a user or customer could have with a system. Formerly used only in computer programming, use case diagrams have become popular in the retail and customer service industries to explain how customers interact with a business.

While they are still primarily used for computer programming and other technical fields, use case diagrams have gained wider use in other business areas, and many organizations create use case diagrams to help them visualize all the ways a person might interact with their company.

In a business context, organizations can create use case diagrams or illustrations to visualize their sales and marketing flow, describe typical interactions with their technology or applications or analyze a complex workflow.

The four elements of a use case diagram are:

  • Relationships

In other words, a use case diagram should visualize a reason (use case) why an individual (actor) would interact with your organization (system) and the relationships between the business and the individuals.

Use case diagrams can be simple in how they visualize these four elements, as in the example below that describes why (use cases) two types of customers (actors) might interact with a bank (system) and the relationships that result.

These types of diagrams can also be complicated and describe many types of functions that may or may not always take place in the course of an individual’s relationship with a system. This example illustrates some use cases that will always occur and some that may occur.

Use case diagrams not right for your needs? Try a flowchart instead. Also check out our collection of 20+ flowchart templates and examples professionally designed for you.

First, you need to organize your four key elements — system, actors, use cases and relationships. Then, arrange them visually in a way that makes sense and will allow you to see immediately the connections between them.

Some use case diagrams also establish certain steps that may need to be a part of every use case in question or only some; it’s typical to use the terms “include” or “extend” to do this, as in the example below.

use case diagram

Here’s a good primer to help you understand the difference:

  • Extend : When describing an ATM use case, you would use an exclude line or connection a conditional scenario, say, if a user doesn’t bank with that institution normally and must pay a fee to withdraw cash.
  • Include : In our ATM use case example, this could apply to a user putting their card into the machine, entering their PIN and being shown a menu.

In other words, interactions that always happen should be described with an include notation, while those that may happen under certain conditions should be described with an extend notation.

How to create a use case diagram using Venngage

Let’s check out some additional use case diagram examples that may help inspire you to come up with a new way to visualize an internal process or customer interaction with your organization.

This business use case diagram illustrates a contract management system using the extend/include function to explain processes that happen with each customer and ones that may happen, though not in every case.

use case diagram

In this use case diagram, we see the simpler method to describing a series of interactions two different customers can have with a bank (and a banking employee). This type of diagram is appropriate for comparing these customers with each other and not necessarily visualizing every possible interaction they could have with the employee.

use case diagram

Going back to our ATM example, this use case diagram illustrates interactions that occur for each individual (bank customer and administrator) and ones that only occur for some (a customer entering a bad PIN). This type of use case diagram would be useful for organizations that need to visualize multiple types of actors on a single diagram.

use case diagram

This use case diagram visualizes interactions a customer could have with their travel agent, including some that occur every time (include) and some that occur under certain conditions (extend). Notably, this use case diagram also illustrates how the agent then interacts with two other systems, airline and touring companies, making it ideal for processes involving third-party vendors.

FAQs about use case diagrams

What is uml.

Use case diagrams are not unrelated to UML, which stands for Unified Modeling Language, which is popular in software engineering. In UML, engineers can create many types of diagrams to help them understand and accurately program a variety of information and interactions.

UML has two broad categories of diagrams, structural and behavioral, and use case diagrams fall into the second category. That’s because they describe the behavior of the individual user as it relates to the system in question.

How do you explain UML diagrams?

UML diagrams are a method of creating a visual representation of a system, including actors, actions, roles, classes and more, in order to better understand or document functions and information about a system.

How are UML and use case diagrams different?

Some UML diagrams are use case diagrams, but not all use case diagrams are created under the UML model, and there are many more types of diagrams that can help support a UML-based methodology.

Here are just a few of the types of diagrams possible with UML:

  • Class diagram
  • Component diagram
  • Composite structure diagram
  • Deployment diagram
  • Object diagram
  • Package diagram
  • Profile diagram
  • Activity diagram
  • Communications diagram
  • Interaction overview diagram
  • Sequence diagram
  • State diagram
  • Timing diagram
  • Use case diagram

In summary: Create a use case diagram to help your organization visualize important processes and relationships

With Venngage Diagram Maker , you can create a use case diagram in just a few steps, ensuring that it follows your brand guidelines with a couple of clicks. Our diagram templates are created by professional designers with you in mind, so you can easily edit them even if you don’t have much design experience. It’s free to get started.

  • September 20, 2022

UML diagrams are an important component of the project report that defines the project architecture, helps to understand the user flow and more organized way to maintain the resources following are different UML diagrams for Tourism Management.

  • Sequence diagrams

Online Tourism Management System will come with some solutions that going to solve lots of problems like a tourist can book his holiday packages before leaving his own house. That includes all the accommodation and the in-depth details about the places and the hotels.

In this article, we’ve compiled structural UML diagrams i.e. component diagrams, and three types of behavioral UML diagrams i.e. Activity, Sequence, Component, and Use Case diagrams for the Online Tourism Management Project.

Component diagram for Online Tourism Management Project

In an Online Tourism Management system, the connected components by lines represent relationships within the systems. In the diagram, it can be seen that there are components namely product, order, customer, and account. The component diagram below shows the components of the Online Tourism Management System.

It shows how the customer component connects to the other components while using the system. Everything from the account details to product booking to payment flow can be seen in the component diagram.

Users can view all the packages according to the location or types of holidays and adventures. Users can check the price or select any holiday package according to the requirement. The online tourism management system will take responsibility for all the needful things about the customer requirement.

A centralized admin can manage all the actors of the application like tour packages, users, inquiries, etc.

travel management system use case diagram

Activity diagram for Online Tourism Management Project

Activity diagrams in UML display the functionalities of various activities and flow in management processes and software systems. The flow in the activity diagram can be sequential, branched, or concurrent.

Admin can view the list of users. Admin can manage the category of packages and can update all package detail. Admin can view booking history and detail. Admin can manage inquiries, issues, payments, and transactions.

Online customers can browse or search packages, view specific packages, view them, book, and checkout. Users can view booking history at any time. Users can make payments for the booking and view the payment history.

Use Case Diagram for Online Tourism Management Project

A UML use case diagram can create a broad, high-level view of the relationship between use cases, actors involved, and systems being performed.

As you can see from the examples below, use cases are represented by oval shapes, and the lines then show at which point an actor/user participates and interacts with their corresponding use case. You can see where each actor is involved within the entire process (and where they’re excluded).

Here, Admin will have the access to Add/Remove packages, answer inquiries, etc. Whereas, Users can view package lists, make inquiries, make payments, book packages, etc.

travel management system use case diagram

DFD Diagram for Online Tourism Management Project

A DFD maps out the flow of information for any process or system. It gives a basic overview of the whole system or process being analyzed. It shows the system with its relationship to external entities. Here, we can see how a system’s users and process flow work.

Initially, Admin and User must be logged in to the system. Upon logging in, both Admin and User will land on the home page where they can manage their profiles, view products, check prices of products, view cart, etc.

Admin manages the booking history, which is the bookings made by the users. Users can also view their bookings and payment confirmation on the system.

How to create user-focused use cases for ideal success scenarios [with examples].

Robert Hales

ClickUp Contributor

December 30, 2023

Are you steering a project, deciphering intricate business processes, or engineering complex software solutions? If so, you’re well aware that success hinges on clarity and precision. Good news! Use cases may spare you and your clients a great deal of trouble.

Imagine you’re constructing a building. Blueprints guide you, outlining each room’s purpose and layout. This is exactly what a use case is: a blueprint to guide system requirements and resulting project operations. It helps map out processes across user interactions, helping you build a system tailored to user goals and needs. 🏗️

A stitch in time saves nine, and similarly, mastering use cases now can save you countless hours later. In this practical guide, we’ll explain:

  • The significance of a use case-driven approach in software development
  • Steps to write a use case for multiple scenarios

Benefits of use cases in business processes

Step 1: come up with the title and description, step 2: identify the actors, step 3: identify the actors’ goal, step 4: capture stakeholders and their interests, step 5: specify pre-conditions or assumptions, step 6: outline basic flow, step 7: determine exceptions or error conditions, step 8: include extensions or variations to how the system functions, step 9: consider alternative flows, create and manage your use cases in clickup docs, try writing use cases with ai, use case #1: online shopping wishlist, use case #2: travel itinerary management.

What Is a Use Case, and What Purpose Does It Serve?

Use cases are indispensable for understanding user-specific interactions and narratives (or user stories) to create the intended design for a system.

In technical terms, a use case is a detailed description that outlines how a user will interact with an IT solution to achieve a specific goal. It maps out the steps they take , with a clear beginning, middle, and end.

If you’re new to use cases, you’re probably wondering why you should care about it. The truth is that every software development process carries the burden of user-focused project planning. It’s critical to understand the service or system requirements beforehand so that your end product works perfectly and is profitable.

This is where a use case comes in, helping you visualize user interactions from start to finish and pinpoint any hiccups along the way . Think of it as a walkthrough in a strategic game where every move is crucial. Your input, the system’s response, specific processes, and the final outcome are all explicitly stated, leaving no room for ambiguity in decisions.

The idea here is to help project managers, business analysts, and software developers align themselves on what the end user desires in a software application or a system , taking the guesswork out of the picture. The result? Smarter decisions on:

  • Features to prioritize
  • Design scope
  • Bugs to fix

Tip: Need a quick start? Use the ClickUp User Story Mapping Template to initiate use case mapping right away! Its built-in infinite Whiteboard helps you track and prioritize user stories within minutes.

User Story Mapping Whiteboard Template by ClickUp

Use cases offer several benefits in developing and managing software systems and projects . Here are seven key advantages for various business stakeholders:

  • Clarity into specific interactions : Use cases provide a clear understanding of how users interact with a system, helping define and document functional requirements
  • Focused communication : Use cases serve as a bridge between business stakeholders , aligning developers, designers, project managers, and clients
  • Identification of how a system behaves : They help identify and document various ways users interact with the system. This includes both normal and exceptional scenarios, providing a comprehensive view of the system’s expected behavior
  • Project planning : Use cases help in planning by breaking down the desired functionalities into manageable units addressing specific system goals
  • Flexibility : They provide a flexible framework that can accommodate modifications (alternative flows) or additions without disrupting the overall system flow
  • Documentation and training : Use cases serve as valuable workflow documentation for future reference. They provide insights that can be useful for training new development team members
  • Risk identification : By exploring various success and failure scenarios, use cases assist in identifying potential risks and challenges early in the development process

What to Include in a Project’s Use Case: With Practical Steps

Use cases can include a number of elements depending on the scale and complexity of the system you’re building. Here are some of the most significant options:

  • Title and description
  • Actors (users)
  • Stakeholders
  • Pre-conditions
  • Exception to the basic flow
  • Variations or what-if scenarios
  • Alternative flows

These points can be better explained when we explore the practical side of things. Refer to the sections below to understand how to include these elements and distill complex use case scenarios into actionable steps .

Any use case study must have an engaging title. Keep it concise, specific, and indicative of the use case’s purpose. For instance, the title Optimizing Online Checkout: A Use Case for E-Commerce Conversion Enhancement immediately conveys the focus and scope.

Next, your case description should set the context concisely, pinpointing the use case actor or user, the system in question, and the ultimate goal. Here’s an example: This use case outlines the steps taken by an online shopper to complete a purchase, highlighting the system’s response at each interaction to ensure a smooth transaction and reduce cart abandonment.

Keep your language sharp, directly addressing the innovative outcomes you seek.

These are not Hollywood stars but rather the key entities— individuals, groups, or even other systems —interacting with the system under scrutiny. Identifying these actors is akin to casting characters in a play; each has a role, a purpose, and a set of actions that contribute to the unfolding narrative. 🎭

Actors within a use case diagram can be categorized as either primary or secondary . A primary actor seeks the system’s assistance by themselves to achieve a specific goal. On the other hand, a secondary actor provides a service to the system as a direct result of the primary use case. The system initiates interaction with the secondary actor for information or completion of a goal.

Let’s say a user applies for a loan online, which makes them the primary actor. In response to the loan application, the system triggers another resource to calculate interest rates—that resource is the secondary actor.

If you’re still in the research phase and need help identifying the primary actor, you may want to document your findings through the ClickUp User Research Plan Template . Its built-in features help software and UX teams map out user behavior and resolve problems within apps, websites, or projects in an orderly manner. 

ClickUp User Research Plan Template

Whether an actor is buying a product, signing up for a newsletter, or using a website, their goal is the driving force behind their interaction with your services . It’s your job to understand these goals so you can design a system that helps them achieve them in the most efficient way possible.

Let’s consider a real-world example: if you’re running a retail website, a customer’s goal might be to purchase a product in minimal steps. This use case would require you to outline the steps customers need to take to complete that purchase, from selecting the item to finalizing the payment.

Use this ClickUp SMART Goal Action Plan Template to list out the goals of all identified actors and monitor how they’re addressed by your team.

ClickUp Smart Goal Action Plan Template

It’s super vital to identify all the stakeholders and understand their interests to ensure your use case is effective. A stakeholder could be an end-user, a system administrator, or even external actors or systems interacting with your service. They all have unique needs and expectations. Here’s what you should do:

  • List all possible stakeholders involved in the use case
  • For each stakeholder, identify their interests or what they aim to gain from the use case. For instance, a potential Interest for an online shopper would be an Intuitive and efficient user experience
  • Consider how the use case can be fulfilled without compromising the overall goals
  • Regularly revisit this list as your project or product develops , ensuring new needs are accounted for

Stakeholder analysis can be a stressful job, especially when there are multiple use cases to monitor. We recommend using quality stakeholder mapping templates to structure the process. 

ClickUp Stakeholder Analysis Template

Pre-conditions set the stage for action, ensuring that all necessary conditions are in place before the use case is initiated. Think must-haves for your scenario to work—like having an internet connection for an online transaction or a user account for access to a members-only area. Imagine the scenario from the user’s perspective and identify and list these prerequisites clearly.

Here’s an illustration showing how pre-conditions are used to outline use cases and automate the workflow for a banking website:

Use Case Pre-conditions Diagram.png

This is the minimum viable product (MVP) scenario, the one where everything clicks, and your use case unfolds just as envisioned. No errors, no hiccups, just a straightforward path to a happy user.

Imagine a scenario where a customer purchases a book from an online store. The basic flow would be:

  • The customer logs in to their account
  • They search for a book by title, author, or genre
  • The customer reviews the book and adds it to their cart
  • They proceed to checkout, confirm shipping details, and select a payment method
  • They review the order summary and place the order
  • A confirmation email is sent to the customer

Each step here is supposed to be clear and necessary, guiding the user towards a satisfying transaction. Fall back on the ClickUp User Flow Template to design efficient use case pathways and share them with your team.

These exceptions represent scenarios where the standard process flow doesn’t apply. Think about what could go wrong and how your system should respond. You can:

  • Consider realistic scenarios : Think about all the ways an operation might deviate or lead to failure scenarios. This could be due to technical issues, user errors, or unexpected circumstances
  • Document each exception : Clearly describe each exception, including its cause, effect, and how your system should respond
  • Prioritize exceptions : Rank exceptions based on their likelihood and impact on user experience

Think of these as what-if scenarios that keep your processes agile . Say if a customer abandons their shopping cart, what’s the next step? This perhaps calls for creating an extension that activates a follow-up email sequence or a special discount offer to re-engage them.

Use cases should adapt to real-world complexities, offering innovative solutions that maintain user engagement. It’s about anticipating the unexpected and scripting a response that turns challenges into opportunities.

Consider alternative courses if challenges or process deviations occur. Imagine you’re designing a use case for an online shopping cart system.

Main Success Scenario (MSS):

  • The user adds items to the cart
  • The user proceeds to checkout and confirms payment

What if an item is out of stock?

  • The system notifies the user immediately
  • The system recommends similar products

What if the payment is declined?

  • Prompt the user to try a different payment method
  • Offer to save the cart for later completion

What if network issues occur?

  • Save the user’s progress automatically
  • Inform the user and attempt to reconnect

For each what-if , develop an alternative path that guides your system to a successful outcome.
