A Reliability Prediction is a way to analyze an electro-mechanical system to determine its predicted failure rate. Sometimes Reliability Prediction analysis is referred to as MTBF analysis. MTBF (Mean Time Between Failure or Mean Time Before Failure) and failure rate are related metrics in reliability engineering. Learn more about MTBF.
Reliability Predictions take into account all the components in your system along with design and environmental parameters known to effect reliability such as operating stresses, temperature, environment, and procurement quality level. A Reliability Prediction analysis uses underlying mathematical equations developed based on historical and known failure metrics to compute a predicted failure rate of your product.
One of the main advantages of reliability predictions is that they can be performed during the product design stage, enabling you to preview likely reliability metrics prior to manufacture and deployment. This enables you to design-in reliability, so you can be confident your product will achieve your reliability and quality goals when built.
In the product lifecycle, the cost of correcting a failure dramatically increases along every stage of a product’s life. In early design, design changes incur minimal cost: engineering time associated with the redesign. Design changes required later to correct defects incur huge costs – manufacturing line downtime, recalls, product replacement, etc. – not to mention the immeasurable negative costs to your reputation and corporate standing. Reliability Predictions are a fundamental and proven approach for early reliability assessment.
Reliability Predictions also provide a way to perform What-If? analyses. What-If scenarios allow you to quantifiably measure the reliability of various design alternatives. For example, you may have two proposed designs for a specific subsystem. Using Reliability Prediction MTBF analysis, you can view the reliability profile of each design and make a decision based on clear metrics.
Lastly, Reliability Predictions may be performed to meet compliance requirements. In some situations, vendors may be contractually obligated to meet specific MTBF goals. Armed with MTBF assessments from Reliability Prediction analyses, your compliance requirements can be attained.

Although it is possible to perform Reliability Predictions by hand or with simple Excel spreadsheets, the most efficient way is to use a Reliability Prediction software package designed and built expressly for this purpose.
Reliability Prediction software should support the most commonly used and accepted standards, and the most recent editions of those standards. Widely used standards for Reliability Predictions include MIL-HDBK-217, Telcordia SR-332, and 217Plus.
Each standard varies and also has its own unique set of features to augment and improve MTBF analysis, such as adjustments for laboratory and field-based data. Reliability Prediction software should implement each standard fully. It’s even better if the Reliability Prediction package allows you to utilize these additional features across all standards for improved MTBF predictions – referred to as model extensibility.
Beyond the core capabilities defined in the standards, strong Reliability Prediction packages offer a wealth of capabilities for efficiency and automation such as:
- Built-in component libraries for easy look-up of device data and the ability to have your own internal component device database
- Built-in default data values and user-definable default values so MTBF analysis can be done before all design parameters are finalized
- Custom reports, graphs, and dashboard overviews
- Support for What-If? analysis and Mission Profiles
- Ability to import BOMs (Bill of Materials)
- Easy integration with other reliability tools
