• Reliability block diagrams (RBD)
• Weibull life modeling
• Acceleration factor calculations

Define:

• Product lifetime targets (based on usage)
• Duty cycle assumptions
• Environmental stress levels (Country specific conditions)

2 DVT Architecture & Governance

• Define risk-based DVT framework
• Establish entry/exit criteria for EVT/DVT/PVT
• Review and approve test plans
• Ensure subsystem coverage including RF robustness, Thermal printer head life, Cutter mechanical life, SMPS robustness, LCD burn-in, Life for keyboard switches
• Implement structured issue tracking and severity classification

3 Product-Specific Reliability Focus
