MIT SDM Systems Thinking Webinar Series
Madhav S. Phadke, PhD
President, Phadke Associates Inc.
Date: June 28, 2011
About the Presentation
Software and system testing costs hundreds of millions of dollars annually. Testing also takes multiple months, delaying time to market. Several major defense and commercial firms are therefore embarking on using orthogonal arrays (OAs) to reduce the cost of testing and time to market while ensuring that technology defects are not passed onto the customer.
OAs provide a systematic, scientific, and repeatable approach to generating test plans that reduce testing costs by an estimated 40 percent while providing additional capacity to detect faults. OAs also have distinct advantages for results analysis and defect isolation, delivering savings throughout the life cycle.
In this webinar, Dr. Phadke will describe the fundamentals of using OAs for test planning using examples from defense systems; present results of 20 side-by-side IT and software testing pilots conducted in the financial services industry; compare OA-based testing with other test planning methods (pairwise, n-way, and design of experiments); and describe a commercial software toolset (rdExpert™ Test Suite) used for OA-based testing.
