Validation plan
Fri, Mar 19, 2027 · Week 9 · Biotechnology for Health (Biomedical Innovations)
Today's goal: Design a test plan that defines the metrics needed to validate your prototype.
What a finished product looks like
This is a model of the work you should turn in today. Use it to check your own: match the structure and the level of detail, do not copy it. Your data and wording should be your own.
Prototype claim: My reminder device gets users to take medication within 15 minutes of the scheduled time.
Metric 1: On-time dosing rate, in percent. Pass threshold: at least 80 percent of doses taken within 15 minutes of schedule.
Metric 2: Time-to-response, in minutes. Pass threshold: average response under 5 minutes after the alert.
Procedure: Run 10 scheduled reminders per test user over one week. Log whether each dose was taken within the 15-minute window and the response time. A user passes if both thresholds are met.
Control: A baseline week with no reminder device, so I can tell whether the device, not memory alone, caused any improvement.
Error source and reduction: Users might forget to log their own doses (recording error). I reduce this by having the device auto-timestamp each acknowledged alert instead of relying on a paper log.
Also due today: Submit the validation plan in the course LMS before the end of class.
