I am looking for good examples of UI’s that rate the efficiency of a system and score it accordingly, providing the feedback to the operator. The challenge being, since the score is based on real time data analysis, the 100% goal line can increase upwards as the system gets more data, learns the breadth of possibilities and recalculates the best efficiency goal.
For example, a water treatment plant. The operators of the plant are monitoring the pumps. On their monitors they see a percentage score of how well the pumps are running in relation to the optimal 100% score which the real time data analysis has calculated.
The operator glances at the screen from across the room and sees that pumps are at 80 % efficiency based on the settings the operator has chosen. The operator is interrupted for two minutes by a phone call and when they look again at the screen the score has dropped from 80% to 60%. The operator is puzzled as to why the score dropped because they did not make any changes to pump pressure, flow etc.
Because in that two minutes the system had gathered more real time analysis and had recalculated the optimal 100% goal line. What was an 80% efficient plant operation is now considered only 60% of optimal.
I am finding this idea of a moving goal line a very challenging concept to explain without a status bar, or help text.
If there are ideas or examples out there I would love to hear or see them. Right now I am thinking this is falling into what Jared Spool calls the Magic Escalator of Acquired Knowledge.
