Verified - Reliability Toolkit Commercial Practices Edition

1. Introduction to Reliability

• Availability first: Prioritize customer-visible uptime metrics (SLA/ SLO) tied to revenue/contract impact.
• Cost-aware resilience: Balance redundancy and recovery speed against operational and capital cost. Use cost-per-minute-of-downtime to guide tradeoffs.
• Detect early, remediate fast: Shorten mean time to detection (MTTD) and mean time to repair (MTTR) to limit business impact.
• Risk-based prioritization: Focus engineering attention where failures cause the largest financial, regulatory, or reputational harm.
• Observable & measurable: Instrument to map technical signals to business outcomes; ensure reliability decisions are data-driven.

• Collect and analyze field data on failures.
• Use this data to improve design and manufacturing processes.

The toolkit is organized into practical modules that mirror the product development lifecycle:
