17.3 Team Software ProcessSM

15.3 Team Software Process ^SM

The benefits of using the Team Software Process ^SM to help produce 10,000 lines of code are $4,341,496. This was obtained by subtracting $168,501 in new total life cycle costs from $4,509,997 in old total life cycle costs.

The special, new, or additional costs that are required to introduce the Team Software Process ^SM consist of only the training cost. The training cost to use the Team Software Process ^SM to help produce 10,000 lines of code is $148,400.

This is a conservative estimate of Team Software Process ^SM training costs. There are many more courses that must be taken.

The development cost of $168,501 was not included as a Team Software Process ^SM cost. The development cost actually decreased. Had the development cost of using the Team Software Process ^SM increased, the difference or increase would have been included. Table 16 illustrates the B/CR of the Team Software Process ^SM .

SPI Method	Benefits/Costs
TSP SM Benefits	$4,341,496
TSP SM Costs	$148,400
B/CR	29:1

Now we are ready to determine the B/CR of the Team Software Process ^SM to help produce 10,000 lines of code. Divide the benefits of $4,341,496 by the costs of $148,400 for the Team Software Process ^SM . The B/CR of using the Team Software Process ^SM to help produce 10,000 lines of code is 29:1.
