Companies and organizations develop products for sale to other people, companies, and organizations.

Doing a good job of specifying the design requirements up front will almost always speed up development of a product and make it go much more smoothly. These design requirements not only include the functions and features desired by users, but:

During development, a company may easily have ten times as many programmers/ engineers and testers working on the software/firmware as on the hardware. But during production, replication of the software/firmware is a nit compared to the time/effort/money spent: Some major concerns when developing a product are: During development, new electronic products share many of the characteristics of electronic equipment. But design, development, and testing must be done much more rigorously to meet all the legal requirements. Documentation must be very thorough and complete to meet the needs of: The Robust Electronic Design process asks designers and developers to adopt a "from the cradle to the grave" viewpoint of the product. Starting with the earliest concepts, and clear into production, we need to consider:
  1. Our customers:
  2. Our design and development process:
  3. Our manufacturing process(es):
  4. Service:
  5. The ultimate disposal of the equipment/product:

dBi Corporation was a one-man test house (testing laboratory) based in Lexington, Kentucky, testing a wide variety of commercial electronic products for electromagnetic compatibility (EMC), electromagnetic interference (EMI), and electrostatic discharge (ESD) under its ISO 17025 accreditation. dBi was founded in Winchester, Kentucky in 1995 by Donald R. Bush, shortly after he retired from 30 years service with IBM Lexington's/ Lexmark's EMC Lab. John R. Barnes, who'd worked with Don at IBM Lexington and Lexmark, bought dBi in 2002 after Don's death, and moved the company to Lexington, Kentucky. John closed dBi at 11:59pm EDT on September 30, 2013, because ObamaCrap had increased operating expenses to the point that we could no longer afford to remain in business.

We'd like to thank all of the clients who chose dBi to test their products from 1995 to 2013. Below is a brief summary of our accomplishments during the 18 years we were in business.

From 1995 to 2001, under Don Bush's ownership and operation, dBi:
