Question
Chapter 7, Problem 3P
a)
Summary Introduction
To determine: The average cycle time for each operation.
Introduction: The amount of the dependency on human effort by an organization in terms of achieving its goals is given by the work design. It is directly linked to the productivity of an organization where good work design helps in achieving high productivity.
b)
Summary Introduction
To determine: The normal time for the operation.
c)

Based on a careful work study in the Hofstetter Corp., the results shown in the following table have been observed: a) Compute the normal time for each work element.b) If the allowance for this type of work is 15%, what is the standard time?c) How many observations are needed for a 95% confidence level within ±5% accuracy? (Hint: Calculate the sample size of each element.)
Ergonomics problem
A work measurement analyst in the Electrical Company took 10 observations (for each element) of an operation job. The operation consists of four elements of work. Result of observation was shown in a Table attached.
a. Determine the standard time and standard output if the total allowance time is 12%
b. Check whether number of observation is sufficient or not for a 95 percent confidence level and 5 percent significant level.
