The criteria for passing the final acceptance test will be:   The on-line help function provides relevant help to the operator in most situations, and the  terminology is clear and consistent.  The purpose of the efficiency test is to verify that the operation and response times are at an acceptable  level. The verification of efficiency values shall be based on well-defined situations. The operator shall  perform different kind of situations:   Changing a set-point/sending a command.   Open an graph.   Open a new diagram.   Require a report based on historical data's.  Five different types of response times have to be taken into account:   Response time for a transaction, which is the time interval from sending a command until the  result is visible and the user can send a new command. Sending a command can be executed by  the "Enter"-button, by a mouse click etc. This type of transaction is defined as typing data in an  input data field with no calculations, change of diagram etc. related to the transaction.   Response time for opening a new part of the program, such as a new diagram. Opening a diagram  for the first time after start of the program may take longer time.   Response time for opening a graph showing curves for 24 hours. In this case, the response time is  the time interval from sending an "open graph" command until the result is visible.   Response time for opening a report showing values for 1 month. In this case, the response time is  the time interval from sending an "open report" command until the result is visible.   Response time for creating a background job such as a printing command.   The response time for sending a command is almost negligible (less than 1 second). Return of the  value from the shall be fulfilled within 2 seconds.  The criteria for passing the final acceptance test will be:   The response time for opening a new diagram is less than 2 seconds.  The response time for opening a graph is less than 10 seconds.  The response time for opening a report is less than 20 seconds. All tests shall take place from the secondary operator station (not the server). The purpose of the accuracy test is to verify that the system generates correct output results. Based on the detailed project for automation the functionality described here shall be verified.
