RISKS
5 – Life Threatening4 - Nonfunctional Prototype3 – Fixable Glitch2- Outside of Design Control1 – Not critical to functionality
Risk Level How to Mitigate
False positive/negative on biometric scanner 5 Use best possible scanner within budget
Incorrect medication fill 5 Individual held accountable - datalogging, pick list
Dispensing from incorrect location 5 Double-check programming, circuitry
Hardware compatibility (USB drivers) 4 Test on multiple computers, make sure drivers are up to date
Unauthorized access 4 Fingerprint access, any access is logged
Power Outage 4 Advise customer to supply UPS
Dropping / Impact 3 Ensure case design is robust
Biometric scanner malfunction 3 Users will have a backup PIN
OS compatibility 3 Test on multiple computers, include necessary software
Firmware patches 3 Ensure updates can be made easily using OS
Incomplete or Incorrect Documentation 3 Evaluate and organize
Mechanical Jam 3 Careful selection of hinges/validation testing
User forgets to take medication 2 Alarm/indicator on unit
Pill breakage 2 Pad cartridge caps
Return slot full 2 Properly sized return area
Water damage 1 Alert users with warning label
Excessive Weight 1 Re-evaluate Concept Selection32
ISSUES (Most important to least)
1. Time2. Scope Creep3. Availability of machine shop/electrical
components/Nitinol fibers & latches4. OS updates5. Team schedules conflicting6. Available computers/people for testing7. Ramp packaging space (hinge thickness)8. Cartridge loaded and delivered in different
time zones33
