A methods and measurements analyst for Timepiece, Inc., needs to develop a time standard for the task of attaching a watch to a wristband. In a preliminary study, he observed one of his workers perform this task five times, with the following results:

Observation: Time (secs):
1 27
2 19
3 20
4 21
5 13

What is the standard time for this task if the employee worked at a 20 percent faster pace than average, and an allowance of 20 percent of the workday is used?

Answer:

The standard time for the task is 28.8 seconds

Explanation:

The question is to determine the standard time for the task of attaching a watch to a wristband

Step 1: What is the observed time for the task

Observed time = the Sum of Task times ÷ The Total Number of Observations

= Sum of task times 27 + 19+ 20 + 21 + 13 = 100

= 100/5

Observed Time = 20 Seconds

Step 2: Determine the Normal time expected for the task

= The formula for Normal time = Observed time x The Determined Performance rating

= Observed time = 20 Seconds

Performance Rating = 100 (the average rating ) + 20% (the employee worked 20% faster pace than average)

=100 + 20 = 120% or 1.2

Therefore, Normal time = 20 seconds x 1.20 = 24 Seconds

Step 3: Determine the Standard time

=Standard time = Normal time (Step b above) x (1 + Allowance for employee for the task)

Normal time = 24 seconds

Allowance for the task = 20% or 0.2

Standard Time = 24 seconds x (1+0.2)

= 24 x 1.2 = 28.8 seconds
