The WUSACC Framework: The Ultimate Method for Defining High-Performance Use Cases in 2025
What Is the WUSACC Framework?
WUSACC is an acronym that structures the definition of a use case across six interdependent components:
WHO, USES, SO THAT, ACHIEVE, CONTEXT, and CONSTRAINTS.
- WHO defines exactly who the user is.
- USES identifies the specific action they perform.
- SO THAT clarifies the intermediate goal.
- ACHIEVE defines the final business outcome.
- CONTEXT describes the environment in which the action takes place.
- CONSTRAINTS outlines the limitations or restrictions the user faces.
This methodology ensures that every use case is specific, measurable, and aligned with a concrete business objective.
The WUSACC approach pushes product teams to ask the right questions early in the discovery phase — avoiding months of development in the wrong direction.
The Six Pillars of the WUSACC Framework
1. WHO — Who Is the User?
The first step of the WUSACC framework is defining exactly who will use your feature.
This dimension accounts for 20 out of 100 total points in the WUSACC scoring system, reflecting its critical importance.
A vague persona equals an unusable use case — it’s impossible to design a meaningful solution without knowing the person behind it.
To define the WHO dimension properly, four key criteria must be validated:
job title, seniority level, team size, and industry.
A poor example would simply be “a manager.”
A strong example would be:
“A Head of Customer Support with 8–10 years of experience, managing a team of 25 agents in a B2B SaaS scale-up with 150–300 employees.”
The more detailed your persona, the more accurately you can tailor your solution to their real context — their responsibilities, constraints, tools, and success metrics.
2. USES — What Does the User Do?
The second pillar focuses on defining the specific action the user performs.
This dimension, worth 15 points, plays a crucial role in making the use case actionable.
The action must include a clear verb and a concrete object.
Saying “use the tool” is meaningless.
Saying “automatically analyze call transcripts to detect regulatory non-compliance” provides actionable, testable value.
The more specific the action, the easier it becomes to design, measure, and automate.
A weak example would be “manage feedback.”
A strong example would be:
“Automatically categorize 500 multi-channel customer feedbacks per week according to a custom taxonomy of 15 categories, including bugs, feature requests, and UX issues.”
This level of precision instantly aligns product, technical, and business teams around a shared understanding of the goal.
3. SO THAT — What Is the Immediate Purpose?
This dimension, often overlooked, defines the intermediate purpose — the operational “why” behind the action.
It clarifies what the user is trying to achieve right after performing the action.
For example:
“Automatically analyze call transcripts to identify discrepancies in agent scripts.”
Without a clear “so that,” a use case becomes just a task — not a purposeful step in the user journey.
4. ACHIEVE — What Is the Final Business Outcome?
The ACHIEVE pillar translates operational success into business impact.
It connects the use case to measurable outcomes such as time saved, reduced errors, higher satisfaction, or increased revenue.
Example:
“Analyze call transcripts to identify agent discrepancies, reducing quality-audit non-compliance rates by 30%.”
This step ties the use case directly to strategic objectives, giving it both operational and executive relevance.
5. CONTEXT — In What Situation?
A use case doesn’t exist in isolation.
The CONTEXT pillar defines the conditions in which it operates — the volume, frequency, environment, or technical constraints.
Example:
“In a support center with 200 agents across three time zones, where 80% of interactions occur by phone.”
By anchoring the use case in its real environment, teams avoid designing solutions that look perfect on paper but fail in the field.
6. CONSTRAINTS — What Are the Limitations?
Finally, CONSTRAINTS define the boundaries of feasibility:
time, budget, compliance, technical dependencies, or legal frameworks.
Example:
“Under GDPR compliance, with call recordings retained for a maximum of 30 days and data processing limited to France.”
Far from limiting creativity, constraints make the use case realistic — ensuring it can be executed and measured effectively.
Why the WUSACC Framework Changes Everything
The WUSACC approach imposes a level of discipline that transforms how teams define, evaluate, and prioritize their projects.
It creates a shared language between product, engineering, and business teams.
Each use case becomes a measurable, comparable, and prioritizable unit.
By applying this structure, teams report spending 40% less time re-defining requirements, while increasing stakeholder satisfaction by nearly 60%, based on client feedback.
Conclusion: From Subjectivity to Product Science
The WUSACC framework is not just a documentation template — it’s a strategic thinking tool.
It pushes teams to translate assumptions into measurable statements, link user needs to business outcomes, and anticipate constraints before they block progress.
In a world where product teams are expected to prove impact faster than ever, structuring your use cases with WUSACC is no longer optional — it’s a competitive advantage.
