Introduction
In the digital era, it is easy to forget that every software instruction eventually runs on a physical substrate. Unlike software, hardware is subject to the laws of physics: it wears out, it overheats, and it can break under mechanical stress. Risk Management for Hardware is the systematic process of identifying and mitigating the physical vulnerabilities of a product’s components and assemblies.
Within a Product Lifecycle Management (PLM) framework, hardware risk management ensures that the “As-Designed” product can survive its intended environment for its entire lifecycle. It moves beyond simple “pass/fail” testing to a predictive model where risks are managed from the selection of the first capacitor to the final assembly on the factory floor.
Key Categories of Hardware Risks
To build a robust hardware risk profile, engineers must analyze three critical dimensions:
1. Component-Level Risks
Every part in the Bill of Materials (BoM) has a failure rate. Managing this involves:
- Derating: Operating components below their maximum rated limits (e.g., using a 50V capacitor in a 25V circuit) to increase longevity.
- Obsolescence: The risk that a critical chip will be discontinued by the manufacturer during the product’s life.
2. Design and Integration Risks
Risks that emerge when components interact.
- Thermal Management: Will the heat from the processor cause the solder joints of the RAM to crack over time?
- Signal Integrity: Will electromagnetic interference (EMI) between high-speed traces cause data corruption?
3. Supply Chain and Manufacturing Risks
The risk that the hardware cannot be built or that its quality will vary.
- Single-Source Vulnerability: Depending on a one-of-a-kind component that could become unavailable due to geopolitical or logistical issues.
- Manufacturing Defects: Risks related to ESD (Electrostatic Discharge) during assembly or poor solder quality.
Methodologies for Hardware Risk Assessment
- Hardware FMEA (Failure Mode and Effects Analysis): Examining each hardware block to determine the effect of its failure on the entire system.
- MTBF (Mean Time Between Failures) Calculation: Using statistical models to predict the expected reliability of the hardware.
- Physics of Failure (PoF): Using simulation to understand the root causes of physical degradation (e.g., thermal cycling, vibration fatigue).
The Strategic Role of Hardware Risk in PLM
| Risk Stage | PLM Integration | Business Value |
| Selection | Linking component data sheets to risk logs. | Avoids using unreliable or “End-of-Life” parts. |
| Simulation | Connecting CAE results (thermal/stress) to the risk matrix. | Validates “Safety Factors” before physical prototyping. |
| Sourcing | Monitoring supplier health and geopolitical stability. | Prevents production line stops due to missing parts. |
How Visure Solutions Mitigates Hardware Risks
Visure Requirements ALM Platform provides the “Single Source of Truth” needed to manage the complex dependencies of hardware risk:
- Risk-Linked Bill of Materials (BoM): Visure allows you to attach risk scores directly to components. If a high-risk component is used in multiple designs, the risk is flagged across the entire portfolio.
- Obsolescence Tracking: Manage the lifecycle status of hardware parts. Visure can alert engineers when a requirement is tied to a component marked for obsolescence.
- Mitigation Traceability: When a hardware risk is identified (e.g., “Overheating Risk”), Visure ensures that a corresponding requirement is created (e.g., “Add Heat Sink with 5W/mK conductivity”) and verified.
- Supplier Risk Management: Document and track supplier certifications and reliability data within the same environment as your technical requirements.
- Automated Reliability Reports: Generate FMEA and risk summary reports for hardware certification (e.g., for ISO 26262 or IEC 61508) with a single click.
Conclusion
Risk Management for Hardware is what transforms a “prototype” into a “product.” It is the discipline of anticipating the invisible forces of nature and the unpredictable nature of global logistics to ensure that the product performs every time the user flips the switch.
By integrating hardware risk management into the PLM lifecycle with Visure, organizations gain the visibility needed to build more reliable, sustainable, and profitable products. When you know your risks down to the component level, you don’t just hope for reliability—you engineer it.
