reliability growth tracking

**Reliability growth tracking** is **continuous monitoring of reliability metrics over test phases to verify that corrective actions deliver measurable improvement** - Dashboards combine failure intensity, MTBF trends, and fix status to track progress against reliability goals. **What Is Reliability growth tracking?** - **Definition**: Continuous monitoring of reliability metrics over test phases to verify that corrective actions deliver measurable improvement. - **Core Mechanism**: Dashboards combine failure intensity, MTBF trends, and fix status to track progress against reliability goals. - **Operational Scope**: It is used across reliability and quality programs to improve failure prevention, corrective learning, and decision consistency. - **Failure Modes**: Tracking only aggregate metrics can mask recurring mechanism-specific failures. **Why Reliability growth tracking Matters** - **Reliability Outcomes**: Strong execution reduces recurring failures and improves long-term field performance. - **Quality Governance**: Structured methods make decisions auditable and repeatable across teams. - **Cost Control**: Better prevention and prioritization reduce scrap, rework, and warranty burden. - **Customer Alignment**: Methods that connect to requirements improve delivered value and trust. - **Scalability**: Standard frameworks support consistent performance across products and operations. **How It Is Used in Practice** - **Method Selection**: Choose method depth based on problem criticality, data maturity, and implementation speed needs. - **Calibration**: Track both overall and mechanism-level trends and require closure evidence for each major fix. - **Validation**: Track recurrence rates, control stability, and correlation between planned actions and measured outcomes. Reliability growth tracking is **a high-leverage practice for reliability and quality-system performance** - It keeps reliability programs accountable to objective performance evidence.
