What you'll get
For shops that make parts for other manufacturers: ISO, the standards body that sells ISO 9001, gives a five-minute overview of what the quality management standard is, who uses it, how it differs from industry versions such as AS9100 and ISO 13485, what an audit and a major nonconformity are, and how a company gets certified. Whether you need certification is usually decided by your customers, so use it to learn the terms before you ask your best prospects what they require, and hold off budgeting for certification until they answer.
Do this week
Ask your three best prospects whether they require suppliers to hold ISO 9001 or another quality certification, and write down what each one says before you price out certification.
