In work design measurement study, explain in your own words, thefollowing terms:
- Observed time (OT)
- Normal time     (NT)
- Standard time  (ST)  Â
An industrial engineer working for you is given an assignment todetermine the standard time (ST) for welding 2 metal parts togetheras a job function.
Your industrial engineer took 5 independent observations of thesame welding job function and recorded the corresponding time ittook to complete the job function. He complied the following tableof data:
Observation                             Weldingtime (in minutes)
- 2.50
- 2.40
- 2.45
- 2.51
- 2.49
If your industrial engineer has assigned a performance rating(PR) of 2.47 to the welding job function together with 15% as anallowance of of job time.
Calculate the respective:
