Services & Capabilities

Usability / Human Factors Testing

Countries: United States, United Kingdom, Germany, Europe
Industries: Medical Devices
Pricing model: Custom pricing
Usability Study Types Offered: Formative study, Summative study
Services Offered: Risk analysis, Instructions evaluation, Validation testing, User interface evaluation, Task analysis
User Types Supported: Lay user, Professional healthcare
Use Environments Supported: Home healthcare, Professional healthcare, Both
Standards Supported: FDA Human Factors Guidance
Has Participant Recruitment: Yes
Participant Recruitment Details: The FDA has requested that manufacturers sub-divide user groups based on other characteristics, such as injection experience and training status, requiring 15 distinct participants for each sub-group. At Design Science, we’ve justified this approach to the FDA and successfully limited sample sizes to 30 participants rather than 60 participants in such cases.
Has Usability Lab: Yes
Lead Time Band: Start in 4-8 weeks
Quote SLA: 3-5 business days
Sample Requirements: The traditional 15 participant per user group sample size requirement is based on research conducted by Faulkner (2003) that suggested a sample size of 15 people was sufficient to find a minimum of 90% and an average of 97% of all problems with a timesheet software. However, given that 15 has been the “magic number” for usability study sample sizes for many years, it will take time to generate enough evidence to support a paradigm shift. For example, consider the variable of injection experience. For a combination product, we typically expect that patient and caregiver user groups will consist of a mix of injection experienced and injection naïve participants. If we apply the “magic number 15” across all sub-groups, our sample size would include 60 lay participants – 15 each of injection experienced and injection naïve patients and caregivers. If we think more critically about the effect of injection experience, it should impact patient and caregiver performance similarly, e.g., by causing additional use errors due to negative transfer or existing mental models. Thus, it is reasonable to use a matrixed approach in which half of the patient participants (approximately 8) and half of the caregiver participants (approximately 7) are injection experienced to reach a total of 15 injection experienced participants and likewise with the injection naïve participants. Thus, we can recruit a total of 15 injection experienced and 15 injection naïve participants across both user groups.
