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.
Benefits of use cases in business processes
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)
- User goals
- Basic flow
- 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.
Step 1: Come up with the title and description
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.
Step 2: Identify the actors
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.
Step 3: Identify the actors’ goal
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.
Step 4: Capture stakeholders and their interests
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
Step 5: Specify pre-conditions or assumptions
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:
Step 6: Outline basic flow
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.
Step 7: Determine exceptions or error conditions
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
Step 8: Include extensions or variations to how the system functions
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.
Step 9: Consider alternative flows
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.
