Standard Time (ST): - Standard Time is the time required by an average
skilled operator. working at a normal place, to perform a specified task
using a prescribed method. It includes
appropriate allowances to allow the person to recover from fatigue and,
where necessary, an additional allowance to cover contingent elements that may
occur but have not been observed.
Observe Time (OT): - Observe time is recorded time to complete any work.
OT= Total Time /
Total Job
Normal Time (NT): - Time taken by an average worker in normal
conditions.
*Rating factor only works in the case of Humans because it will be very human to humans, but the case of machines will be (OT=NT).
RF = If a Normal worker takes more time to complete any job compared to the
observed time NT>OT, so in this case need to rate it.
Example: - Job
= 10 min ͂ OT, Average skill worker
= 12 min ͂ Normal
workers take time
RF = 12/10= 1.2 * 100= 120%
Note: - Allowances are always given with respect to normal time
