1. A quality management system for products comprising:
- a multiplicity of variable barcode indicators, each operative to provide a machine-readable indication of exceedance of at least one threshold by at least one product quality determining parameter, said multiplicity of variable barcode indicators being operative to provide said machine-readable indication only upon said exceedance of said at least one threshold by said at least one product quality determining parameter occurring following actuation thereof, said actuation thereof occurring subsequent to manufacture thereof, each of said multiplicity of variable barcode indicators providing a machine-readable indication;
a) prior to said actuation,b) following said actuation and prior to said exceedance, andc) following said exceedance;
a barcode indicator reader operative to read said variable barcode indicators and to provide output indications; and
an indication interpreter operative to receive said output indications and to provide human sensible, product unit specific, product quality status outputs.

14. A variable barcode indicator operative to provide a machine-readable indication of exceedance of at least one threshold by at least one product quality determining parameter, said variable barcode indicator being operative to provide said machine-readable indication only upon said exceedance of said at least one threshold by said at least one product quality determining parameter occurring following actuation thereof, said actuation thereof occurring subsequent to manufacture thereof, said variable barcode indicator providing a machine-readable indication:
-
a) prior to said actuation, b) following said actuation and prior to said exceedance, and c) following said exceedance.

15. A method for quality management for products comprising:
-
employing a multiplicity of variable barcode indicators each operative to provide a machine-readable indication of exceedance of at least one threshold by at least one product quality determining parameter, said multiplicity of variable barcode indicators being operative to provide said machine-readable indication only upon said exceedance of said at least one threshold by said at least one product quality determining parameter occurring following actuation thereof, said actuation thereof occurring subsequent to manufacture thereof, each of said multiplicity of variable barcode indicators providing a machine-readable indication; a) prior to said actuation, b) following said actuation and prior to said exceedance, and c) following said exceedance; reading said variable barcode indicators and providing output indications therefrom; receiving said output indications; and interpreting said output indications to provide human sensible, product unit specific, product quality status outputs.
