Introduction

I don't know if you've ever used Asana, but when I first started exploring it, I found their product use cases pretty interesting.

Not because it told me what Asana was, but because it showed me what I could do with it. For example, I can integrate it with Slack to automatically send a message to my editor the moment a task is marked "Ready to Edit."

And just like that, I was sold.

If you are building a B2B SaaS product, use case examples are something that you shouldn't miss out on. Why? This article will answer your what, why, and how. You will have clarity on what a use case is, why you need them, and how to create them.

What is a Use Case?

A product use case describes a specific, real-world scenario in which a user, such as a developer, can use your SaaS product to solve a particular problem or achieve a defined outcome. It demonstrates the practical value of your product by showing how it can be used, not just what it does.

Use cases typically include the following components:

• Project Overview: Explains the problem being solved and why it matters in a real-world scenario.
• Architecture Diagram: Shows how your product fits into the overall system or workflow.
• How It Works: Breaks down the flow of data, logic, or interactions step-by-step.
• Pre-requisites: Lists the setup, credentials, or tools needed before getting started.
• Tech Stack: Highlights the core technologies used in the example.
• Setup Instructions: Provides the exact steps to install, configure, and run the solution.
• Code Snippets & Configs: Offers working examples to help users implement or extend the use case.

A well-written use case not only explains functionality but also shows your product in action, solving a specific, valuable problem.

Use Case Examples

The developers in the Infrasity team have created several use case examples for some of the fastest-growing B2B SaaS startups, like Daytona, DevZero, and Scalekit. I have shared a few samples below to help you understand better:

1. DevZero's Use Cases

This is a product use case template library that Infrasity created for DevZero. For example, the developer team made a Todo and Voting App for DevZero users, so that they can just pick up the template and use it directly instead of creating their own without any manual configuration.

2. ScaleKit's Use Cases

For ScaleKit, the developer made a sample web app with Scalekit SDK to showcase its Single Sign-On capabilities with Social Login. It shows that a single integration can be used for multiple IdPs.

3. Daytona's Use Cases

Here is one of the use cases created for Daytona, where the developer connected Daytona workspace with Claude, using MCP. This is so that a user doesn't have to manually verify the generated code from Claude, and it can be done automatically using the Daytona workspace.

Why Do You Need Use Cases for Your Product?

Product use cases help in pitching your product from "Here's what our product can do" to "Here's how you can actually use it to solve your problems." In addition, there are more reasons why you need to create product use case examples:

• Demonstrates Real-World Value

  As we have discussed some of the use case SaaS examples that our team developed for some B2B SaaS startups, they showcase to users how they can use the product in several ways and solve their day-to-day problems.

• Builds Credibility

  It's not just about telling the potential users about your product features. If you showcase those features with product use cases, it will help you build credibility.

• Enhances Market Differentiation

  Every other SaaS company is marketing its product using different marketing techniques. But what the developer audience believes in is something that is robust and evident.

  Use case examples give you an upper hand as you are showcasing the product in a way that will solve their problems, eliminating the process of manually testing everything.

• Facilitates Smooth Customer Onboarding

  Think of well-documented use cases as plug-and-play templates. They give new users a clear path to follow, helping them get started faster, understand the product better, and see real value without having to dig through endless docs, which exactly is what developers appreciate.

• Reduces Churn Rate

  When users know how to use your product to solve their exact problem, they stick around. Ongoing value demonstrated through diverse use cases increases retention and keeps your product relevant as the needs evolve.

Here's What Goes Behind Creating Product Use Case Examples

Creating product use case examples needs a thorough product understanding and approach to make it easier for the target users to use it. Infrasity's team of developers ensures that they create high-quality use case examples and make complex concepts simpler. Here's the process they follow while creating product use cases:

1. Researching About the Product

The developer starts by learning and researching the SaaS product's features and capabilities. They dive into product documentation, how-to guides, and other resources to have complete clarity about the product.

2. Brainstorming Ideas on Use Cases

Once the developer has fully understood the product and its features, they brainstorm ideas on how it can be used to solve different problem aspects. They ensure that those product use cases are practical and innovative, so the potential or existing customer can actually integrate them into their workflow. Then, the developer creates a content plan to document the ideas and follow them.

For example, in one of the above use case ideas, the developer connected Daytona workspace with SmolAgents using Daytona SDK so that it takes a code snippet from the user, parses it, and gives an overview of what it does. Then, it generates test cases for it, which run on a Daytona workspace and return output on the basis of passed and failed test cases.

3. Integrating the Product

With a robust use case idea, the developer integrates the product into a program through APIs, SDKs, libraries, etc., to test its functions.

4. Creating a README File

After the integration is complete, the developer writes a comprehensive use case in the form of a README file using platforms like GitHub Copilot. It explains how the product features work and how to set it up with step-by-step instructions.

5. Designing an Architecture Diagram

The developer uses different tools like Excalidraw, Lucidchart, Whimsical, etc., to design an architecture diagram that provides a picture of the use case and its workflow. It shows how the integration works, making it easy for the end user to understand.

6. Testing the Use Case

To ensure the setup instructions mentioned in the use case are working, it is tested in two steps:

• Internal Testing: The developer who created the use case tests it for any errors, edge cases, proper logs, etc. The dev finds out any irregularities in the program that only a developer can find while using the product feature.

• Testing as a User: It is then shared with other developers for testing to ensure that a new user can use the test case properly, using the instructions provided. This final step involves testing the use case from a new user's perspective to ensure a smooth onboarding experience.

Conclusion

Product use cases are not just nice-to-haves; they're crucial for B2B SaaS startups. Why? Because they help drive real conversions. But more importantly, they shift the conversation from what your product does to how it fits into your user's workflow.

It's not just about showcasing features; it's about giving your target users a clear, actionable understanding of how your product can solve their problems. Use cases bridge the gap between innovation and application. They give your customers value, not just a product.

When done right, use cases build trust, establish credibility, simplify onboarding, reduce churn, and clearly demonstrate how your product delivers real, practical value in everyday workflows.

If you want your SaaS product to stand out, don't just your ideal customer profile what it does. Show them what they can do with it.
