1. A method for determining which of a plurality N of components in a product are responsible for an observed problem of the product, the method comprising:
- identifying a first sample of the product not exhibiting the observed problem;
identifying a second sample of the product exhibiting the observed problem;
dismantling the first sample to obtain N separate first sample components;
dismantling the second sample to obtain N separate second sample components;
producing N new versions of the product, each containing a different one of the N first sample components;
producing N new versions of the product, each containing a different one of the N second sample components; and
determining which of the N second sample components is a source of the observed problem by comparative testing of the N new versions containing a different one of the N second sample components and the N new versions containing a different one of the N first sample components.

Abstract
A method for determining which component of a multi-component product is responsible for a problem with the product features dismantling first and second products—one exhibiting the problem and one not. One different component from each of the original two samples is then used in building a plurality of new products. The new products are then comparatively tested to determine which component or components caused the problem.

5. A method for determining which of a plurality of N sub-components of an automotive vehicle component are responsible for an observed problem of the vehicle component, the method comprising:
-
identifying a first vehicle component exhibiting the observed problem;
identifying a second identical vehicle component not exhibiting the observed problem, but having a usage history substantially identical to that of the first vehicle component;
dismantling the first and second vehicle components to obtain respective first and second sets of N sub-components;
producing a first group of N new components, each containing a different one of the first set of N sub-components;
producing a second group of N new components, each containing a different one of the second set of N sub-components; and
determining which of the first set of N sub-components is a source of the observed problem by comparative testing of the new components of the first and second groups. - View Dependent Claims (6, 7, 8, 9)
