1. A goods reliability evaluation process comprising the following steps:
- at least one host generating information establishing a manufacturer reference site number and at least one supplier reference number for at least one good to be received by said host;
at least one supplier, after conducting reliability tests on at least one good in an least one test period, logs on to a supplier process quality (SPQ) web site and inputs test and failure data;
reliability calculations are then completed to determine the quality of at least one good, wherein said test results automatically generate at least one alarm when predetermined test parameters have been breached.

Abstract
The present invention provides a system by which the host can receive an ongoing reliability audit of a component supplier'"'"'s production test results over the Internet. This invention analyses and graphs the test results to determine component reliability and to detect changes in reliability over time. One parameter used to detect these changes is mean time between failure (MTBF). This invention uses statistical analysis to determine the reliability status and to detect changes in reliability.

14. A control system having a communications link, said control system comprising:
-
at least one server computing unit comprising a supplier process quality (SPQ) program and being coupled to the communications link, wherein said SPQ program comprises a main menu, wherein said main menu is further adapted to enable a user to select at least one of the submenus selected from the group including a characteristic setup menu, a parts setup menu, a process data entry menu, and a report menu; and
at least one supplier computing unit being coupled to the communications link for communicating with said at least one server computing unit;
wherein the SPQ program is adapted to calculate a shift in reliability and the reliability level based on test data provided to the SPQ. - View Dependent Claims (15, 16, 17, 18, 19)

20. An internet based computer program embodied on a computer readable storage medium, said program comprising a code segment that:
-
controls at least one server computing unit, said server computing unit having data acquisition means;
acquires, stores, and displays reliability data from at least one supplier computing unit and at least one host computing unit; and
determines a shift in reliability and generates an alarm when said reliability data is outside a specified range. - View Dependent Claims (21, 22, 23)
