Customer Service Request

Enhancement Definition: A feature not in the original feature set requirement if added will improve the overall feature set of the system.
e.g. : Improves the usability of a product,
Addition of another API or message across the sub-systems or
Addition of another sub-system not required in the initial requirements.

Software CRITICAL: Problem will stop the complete functioning of the system without the fix. The most important feature of the system is not usable.
e.g. : System crashes in normal functioning state or Cumulative problems in the system needing frequent reset or initialization.

Software MAJOR: A complete subsystem function will not work but the rest of the system is operational. System is usable in the default configuration.
e.g. : System availability, System performance not to expectation on peak load or Error handler is not working.

Software MINOR: A problem which does not affect the normal working of the system. But this problem could affect the working of a sub-system without hampering the other sub systems or the overall system. A rare problem not repeatable and has very less impact on the system if it occurs.
e.g. : An optional information element in application user interface is not properly handled, Cosmetic problems like traces / debug information is not complete, Statistics information is not available for some non important features or Adding additional error handlers.
