Question

A time study was conducted on a job that contains four elements. The observed times and performance ratings for six cycles are shown in the following table.

				OBSERVATIONS (minutes per cycle)
Element		Performance Rating			1		2		3		4		5		6
1		80	%		0.51		0.56		0.46		0.46		0.46		0.46
2		75			1.51		1.51		1.46		1.46		1.46		1.51
3		120			0.86		0.86		0.76		0.81		0.86		0.81
4		105			1.11		1.16		1.11		1.16		1.16		1.21

a. Determine the average cycle time for each element. (Round your answers to 3 decimal places.)

Element	Average cycle
1
2
3
4

b. Find the normal time for each element. (Round your answers to 3 decimal places.)

Element	Normal time
1
2
3
4

  
c. Assuming an allowance factor of 21 percent of job time, compute the standard time for this job. (Round your answers to 3 decimal places.)

Element	Standard time
1
2
3
4

Answer 1

Observed time is the time that is taken to complete a particular task. Normal time is the time that is required to train workers so that they can perform particular task. standard time is the time that is required by an average skillet worker, who work at normal pace to perform a specific task.
