Would you like to improve reliability or competitiveness of your product and lower maintenance and warranty costs? Is your customer asking what kind of life-time does your product have? Or, did your product have unexpected failure in the field and you do not know what caused it?
Test planning and tailored testing
Reliability testing without proper test definition or reliability goals is both time consuming and costly. In worst case testing may give you totally incorrect answers how your product will behave in the hands of your customers.
Determining mission profiles helps to select the critical test environments. Correctly defined reliability goals and mission profiles are the key factors for a good design and an efficient test plan.
Test methods should be optimized for each product according to the use environment and used materials. Tailored test methods are often needed, if the aim is to determine or improve reliability of your product.
When doing test planning environmental factors affecting the reliability and lifetime of products are crucial needs to be carefully consdered. This is especially important if you are planning to use new technologies or materials of which you do not have history or field data available.
A key part of reliability analysis is to extrapolate results of accelerated testing to real-time use.
To estimate the lifetimes, prediction models, testing, testing data analysis and know-how gained from performing reliability tests can be used
