The Cure for the System Test & Qualification Headache: Pre-Qualified Systems Slash Design Risk, Lower Costs, and Speed Deployment

Previously qualified systems are ideal for use as the cornerstone of future development. With their inherently lower risk and cost-effectiveness, pre-qualified integrated systems enable system designers to deploy faster, with greatly reduced schedule risk. Typically, when a subsystem is designed from the ground up, the system integrator must submit the new subsystem to a rigorous regimen of testing, both environmental and architectural, to ensure the new design can perform optimally in the harsh defense and aerospace environments in which it's intended to be deployed.
A pre-qualified and verified subsystem eliminates much of the time consuming, costly testing that precedes a new system's deployment. The complex qualification test process that an embedded system must undergo often involves 20-25 individual tests, each of which can cost the system integrator approximately $3,000 USD, while also requiring between one to three days to perform. Qualification testing is a costly and time-consuming process that can add significant risk to development schedules, especially if a test failure results which then requires re-testing and, potentially, re-design. Pre-qualified systems, on the other hand, significantly limit the risk during delta qualification efforts as the base components have been shown to previously pass these tests. This approach also speeds the time it takes to get the system integrators lab up and running, lowering the risk, by allowing the system integrator to begin their development cycle earlier.
Reducing Time and Risk with Pre-Qualified Solutions
A better approach, one that significantly reduces the cost of new system design and greatly speeds application deployment, is to select a pre-qualified integrated system that provides the required processing features in a fully tested and verified solution.
