Normal Time

Observed time adjusted by a performance rating before allowances are added.

Examples

01An operator is timed at 1.8 minutes for a task but rated at 90 % performance, giving a normal time of 1.62 minutes.
02The engineer validates normal time by timing three different operators, so one fast or slow worker does not set the standard.
03Comparing normal time before and after a new fixture shows a true method gain of 0.3 minutes, independent of who is working.
