Reliability Testing Methods: Backing Successful Products

Every company trying to introduce a new product, whether it is software or something else, always wonders how well it will sell, how long it will last in a particular market, and so on. Before a product launch, it has to go through rigorous testing to ensure that it will work properly.

There are several methodologies and testing tools that can estimate the lifespan, but which one should you choose? Here is a look at what a reliability testing method is all about.

The Main Objective of Reliability Testing

These are but some of its goals:

What Does It Involve?

Reliability testing methods assure developers that their product meets all the requirements and is reliable. They consist of three main tests:

  • Reliability Development Tests: These help identify gaps and deficiencies and eliminate them by completing the missed steps. Two methods assist in this process – the Duane Method and the Army Material System Analysis Agency Method.
  • Reliability Qualification Test: In this phase, products undergo testing under specific conditions to see if they comply and adhere to specified parameters and reliability requirements. If they do, then they go into production.
  • Product Reliability Acceptance Testing: After approval from production, you can use the PRAT test to detect degradation in the reliability through the production process.

Under each of these headings, there are several tests carried out to determine the viability of a product.

In the process of determining whether a product can perform or not, it is important to consider the time-based quality concept. Only if a product is subject to different tests through each phase of development can you establish its reliability.
