Question

Chapter 18 Employee Productivity

The first product through a production operation takes 24 minutes, and an 85 percent learning rate is expected.  

a. Estimate the time it will take to produce the third product.

b Estimate the total time it will take to produce the first 20 products.

Answer 1

learning rate (l) = 85%

1st product = 24 minutes

2nd product = 24*l = 24*85% = 20.4 minutes

a) 3rd product = 20.4*85% = 17.34 minutes

b)

Product	Time
1	24.00
2	20.40
3	17.34
4	14.74
5	12.53
6	10.65
7	9.05
8	7.69
9	6.54
10	5.56
11	4.72
12	4.02
13	3.41
14	2.90
15	2.47
16	2.10
17	1.78
18	1.51
19	1.29
20	1.09

the table above shows the time taken per unit for first 20 products:

we add the time for finding total time for 20 products = 153.8 minutes
