Question
Chapter 7, Problem 1TS
a)
Summary Introduction
To determine: The trade-offs in using self-directed teams instead of a more conventional approach using occasional use of teams.
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 time period for making updates at standard times due to minor changes in work methods.
c)
Summary Introduction
To determine: The choice of selection between work time study and work sampling for work measurement.

Shown in Figure are the performance rating factors, RF, and the continuous method recorded times, r, for each work element.a. Calculate the normal time for this job. b. Calculate the standard time for this job, assuming that the allowance is 20 percent of the normal time. c. What is the appropriate sample size for estimating the time for element 2 within {10 percent of the true mean with 95 percent confidence?
(a) What is a technique for estimating the percent of the time a worker spends on various tasks?
A) stopwatch time study
B) simultaneous motion study
C) work sampling
D) standard elemental (historical) times
E) predetermined (published) time standards
(b) A bank manager wants to determine the percent of the time the bank's tellers are working and idle. He decides to use work sampling, and his initial estimate is that the tellers are idle 22% of the time.
