TQM is composed of three paradigms:

* Total: Organization wide * Quality: With its usual Definitions, with all its complexities (External Definition) * Management: The system of managing with steps like Plan, Organize, Control, Lead, Staff, etc.

As defined by the International Organization for Standards (ISO):

"TQM is a management approach for an organization, centered on quality, based on the participation of all its members and aiming at long-term success through customer

One popular test is a "life test" in which the sample product is operated until a part fails. Another popular test is called "shake and bake", in which the product is mounted on a vibrator in an environmental oven, and operated at progressively more extreme vibration and temperatures until something fails. The failure is then isolated and engineers design an improvement.

A commonly-discovered failure is for the product to disintegrate. If fasteners fail, the improvements might be to use measured-tension nutdrivers to ensure that screws don 't come off, or improved adhesives to ensure that parts remain glued.

If a gearbox wears out first, a typical engineering design improvement might be to substitute a brushless stepper motor for a DC motor with a gearbox. The improvement is that a stepper motor has no brushes or gears to wear out, so it lasts ten or more times as long. The stepper motor is more expensive than a DC motor, but cheaper than a DC motor combined with a gearbox. The electronics are radically different, but equally expensive. One disadvantage might be that a stepper motor can hum or whine, and usually needs noise-isolating mounts.

Often, a "TQMed" product is cheaper to produce because of efficiency/performance improvements and because there 's no need to repair dead-on-arrival products, which represents an immensely more desirable product.
