Uncovering usability issues
It is common for HF validation testing to uncover usability issues, especially with critical tasks, leading to some common questions:
- Can we modify the design post-validation?
- Will those changes require further HF testing?
- What testing will need to be conducted?
In this webinar, we cover
Residual risk analysis
Describe the use of residual risk analysis in determining the need for changes following HF validation testing.
Post-validation changes
Explain the nuances of determining whether post-validation changes might require additional HF validation testing.
Scope
Provide insight into how to scope a supplemental HF validation test based on the type and extent of changes.
Additional HF validation testing
Clarify what changes are more likely to require additional HF validation testing, and how to assess these changes.
