Reliability Engineering
Quality confirms that a product works today. Reliability predicts how long it will work tomorrow. The difference between the two determines warranty costs, maintenance intervals, and customer trust. Reliability Engineering provides the analytical tools to turn that prediction from an assumption into a number — early enough to act on it.
Failure Analysis — Find It Before the Customer Does
Proven analytical methods — FMEA and FMECA — systematically identify what can fail, how it will fail, and what the consequences are. Criticality ranking based on severity, occurrence, and detection ensures that engineering resources focus on the failures that matter most, not the ones that are easiest to fix.
Scope of work:
- Failure mode analysis (FMEA / FMECA) with criticality ranking
- Functional failure analysis at system and subsystem level
- Risk prioritisation and mitigation planning
- Standards compliance per ECSS-Q-ST-30-02C and industry-specific norms
Life Data Analysis — Quantify, Don't Estimate
Weibull analysis transforms raw failure data into actionable engineering intelligence. The shape parameter reveals whether failures are driven by infant mortality, random events, or wear-out — each demanding a fundamentally different response. Combined with reliability growth tracking, the analysis provides a clear picture of where a product stands and what it takes to improve.
Scope of work:
- Weibull-based life data analysis and failure prediction
- Reliability modeling and growth tracking
- Warranty period optimisation and maintenance interval definition
- Statistical parameter estimation and confidence assessment
Testing & Qualification — Accelerate the Answer
Identifying design limits early saves months of redesign later. Qualification testing programmes combine accelerated methods with standard-compliant verification — whether the target is a series-production component or a space-qualified assembly.
HALT and HASS testing reveals design weaknesses and screens production defects. Quantitative accelerated life testing extrapolates field performance from compressed test durations. Environmental qualification campaigns — thermal, vibration, shock, EMC — verify survivability under the conditions the product will actually face.
Scope of work:
- HALT / HASS test planning and result interpretation
- Accelerated life test design with stress-life modeling
- Environmental test specification per MIL-STD-810H and ECSS-E-ST-10-03C
- Test-to-field correlation and acceleration factor calculation
