In product development, we throw around a lot of terms. “Epics,” “features,” “tickets,” “stories” but one of the most useful and underappreciated tools is something called a Use Case.
So… what exactly is a Use Case?
A Use Case is a way to describe how someone interacts with your product to get something done. Simple as that.
It’s not about defining a problem (that’s what discovery is for). It’s about describing the journey, how a user interacts with the system, what they expect, what might go wrong, and what should happen after things go right (or wrong).
Let me give you a basic example:
🧍♂️ Player logs in and claims Free Rounds Bonus
That’s a use case. And behind it? There’s a whole flow that touches design, code, analytics, testing and it’s often the glue that connects strategy to execution.
Why Use Cases Matter
Here’s what Use Cases actually solve:
- Clarity across teams: Everyone understands the user journey, from start to finish.
- Alignment: Product, design, and engineering can speak the same language before any code is written.
- Deeper user stories: You’re not just writing “as a user I want…” – you’re backing it up with real flows and outcomes.
Use Cases Through Different Eyes
Let me break down how different roles see Use Cases:
| Role | What Use Case Means to Them |
|---|---|
| CTO | A way to see if product vision translates into sound architecture |
| Product Manager | A bridge between discovery and delivery, tying goals to execution |
| Designer (UX/UI) | Ensures design matches user goals, not just abstract features |
| Developer | Clarifies what to build, edge cases, and expected behaviors |
| Tester | Provides test scenarios, logic, and validation for both happy and error paths |
| Analyst | Offers context for tracking behavior and structuring metrics |
| Architect | Flags which parts of the system are affected and how complex the solution will be |
An Anatomy of a Good Use Case
Here’s the core structure I recommend:
- Title: Clear, action-oriented name (e.g. “Claim Bonus Rounds”)
- Primary Actor: Who’s doing the action (e.g. Player)
- Goal: What they want (e.g. Get bonus spins)
- Preconditions: What must be true before it starts
- Main Flow: Step-by-step journey when all goes well
- Alternative Flows: Optional paths, small detours
- Exceptions: What if something fails?
- Postconditions: What must be true at the end
- Frequency (optional): How often this use case happens
How to Create a Use Case (Step-by-Step)
- Start with a validated problem
You’re not guessing, the discovery already proved this matters. - Define the actor
Who’s taking action? Is it a player, admin, or external system? - Clarify the goal
What does the actor want to achieve? - Set boundaries
Where does the Use Case start and end? - List the preconditions
What needs to be true before this can even begin? - Describe the main flow
This is the “happy path”, if everything works perfectly. - Map alternative flows
What if the user does something unexpected? - Add exceptions
How does the system respond to errors? - Write postconditions
What should be true after success? - Review with your team
Product, design, dev, QA and everyone should align before you break this into tasks.
Aligning With Product Operating Models
Let’s be honest: Use Cases are useless if they don’t fit into the way your product org works. Here’s how they actually support the 4 product risks:
| Risk | How Use Cases Help |
|---|---|
| Value Risk – Will users care? | Use Cases only come after value is validated |
| Usability Risk – Can they use it? | They inform UX flows and expected behavior |
| Feasibility Risk – Can we build it? | They trigger modeling and technical checks |
| Business Risk – Does this make sense for us? | PMs align each Use Case with business goals and OKRs |
Final Thoughts
Use Cases aren’t just a checkbox or a template. They’re a collaborative tool that keeps the team aligned and focused on real user outcomes. They turn abstract goals into clear journeys.
If you roll them out without involving product or design early, you risk ending up with a system that’s technically solid but completely disconnected from what users actually need.
Align early. Build together. Don’t lose sight of the user.
