Compromises
- Wrong actor identification leads to misdevelopments.
- Unclear actor-stakeholder boundary causes diffusion of responsibility.
- Too many target actors dilute focus and resources.
- Combine empirical data with qualitative interviews.
- Keep actor profiles concise and iteratively updatable.
- Link actor definitions to metrics and tests.
I/O & resources
- Stakeholder interviews and user research
- Existing use case descriptions
- Business goals and product roadmap
- Defined target actor profiles
- Prioritized use cases and acceptance criteria
- Mapping to tests, interfaces and metrics
Description
The Target Actor defines the specific actor (user role, external system or group) that a use case or product feature is aimed at. It captures needs, goals and contextual constraints to guide prioritization, scope definition, interface design and tests. Useful in requirements analysis and product strategy. It also aids stakeholder communication.
✔Benefits
- Increased focus in feature decisions.
- Improved test coverage from user perspective.
- Better stakeholder communication through common actor definitions.
✖Limitations
- Simplifying complex user groups may hide details.
- Not all non-functional requirements derive directly from actors.
- Overfitting to single actors can exclude other users.
Trade-offs
Metrics
- Actor Impact Score
Measure of estimated business value or influence of a target actor on a feature.
- Test coverage rate per actor
Percentage of relevant use-case scenarios tested from the actor's perspective.
- Time-to-value for actor features
Time until measurable value delivery for a target actor after release.
Examples & implementations
E-commerce checkout
Target actor: logged-in buyer. Focus on payment and address flow, prioritization of mobile UX.
B2B tenant integration
Target actor: external ERP system. Authentication, mapping and SLA requirements are defined first.
Admin dashboard
Target actor: internal administrator. Priority for monitoring, rollback mechanisms and granular permissions.
Implementation steps
Identify stakeholders and arrange access; interview actors.
Create actor profiles: goals, context, constraints.
Prioritize use cases by actor impact and define acceptance criteria.
⚠️ Technical debt & bottlenecks
Technical debt
- Unclear actor definitions in existing use cases
- Missing linkage between actor profiles and test cases
- Legacy interfaces not aligned with specified target actors
Known bottlenecks
Misuse examples
- Defining a target actor as 'every user' without segmentation
- Ignoring external system actors in integration decisions
- Clinging to a persona despite telemetry showing different priorities
Typical traps
- Confusing stakeholders with target actors
- Generalizing actors too early before validation
- Neglecting system actors in security assumptions
Required skills
Architectural drivers
Constraints
- • Regulatory requirements (privacy) for certain actors
- • Technical integration limits of external systems
- • Time resources for stakeholder interviews
