Supplement to Chapter 9 Work study 265
Average weekly output from Team A is:
85.2 Business visas
39.5 Tourist visas
Average weekly output from Team B is:
53.5 Business visas
100.7 Tourist visas
All team members work a 40-hour week.
The efficiency of each team can be calculated by comparing the actual output in standard
minutes and the time worked in minutes.
Team A processes:
(85.2 × 63) + (39.5 × 55) = 7,540.1 standard minutes of work
in 3 × 40 × 60 minutes = 7,200 minutes
7,540.1
So its efficiency = × 100 = 104.72%
7,200
Team B processes:
(53.5 × 63) + (100.7 × 55) = 8,909 standard minutes of work
in 4 × 40 × 60 minutes = 9,600 minutes
8,909
So its efficiency = × 100 = 92.8%
9,600
The initial evidence therefore seems to suggest that the way Team A has organized itself
is more efficient.
