equipment ?
Module – II
13. a) Discuss various allowances in arriving at standard time.
b) Explain the various predetermined time standards data levels.
14. a) A work sampling study was conducted for 100 hours in a machine shop in order
to estimate the standard time. The total number of observations recorded were
2500. No working activity could be noticed in 400 observations. The ratio
between manual and machine elements was 2 : 1. Average rating factor was
estimated as 1.15 and the total number of articles produced during the study
period were 6000. Rest and personal allowances may be taken as 12% of the
normal time.
