14.3 Team Software ProcessSM

13.3 Team Software Process ^SM

Let's begin by modeling the training costs for implementing the Team Software Process ^SM on a four-person project. The Software Engineering Institute's price for Team Software Process ^SM training is $4,000 per person. The costs for airfare, hotels, meals, and parking are about $2,700 for one week. The length of time for Team Software Process ^SM training is five days or 40 business hours. At a minimum cost of $100 per hour , training time comes to $4,000. Add $4,000, $2,700, and $4,000 and the total is $10,700 per person for Team Software Process ^SM -specific training. Add the $26,400 for Personal Software Process ^SM training to the $10,700 for Team Software Process ^SM training. The total overall costs come to $37,100 per person. Multiply $37,100 by four people and that comes to $148,400 to train four people to perform the Team Software Process ^SM .

Now let's examine the cost of implementing the Team Software Process ^SM by our four trained engineers. Let's assume the project will develop 10,000 lines of code, which once again is not unlikely for a Web project. At an average productivity rate of 5.9347 lines of code per hour, that comes to approximately 1,685 hours. At $100 per hour, that comes to $168,501 for our engineers to produce 10,000 lines of code.

As an aside, the costs of team reviews instead of inspections and testing are already included in the $168,501 implementation cost. The Team Software Process ^SM results in zero defects upon release. Therefore, there are no additional software maintenance costs using our approach to estimating software maintenance effort. Software maintenance is determined by estimating the costs of repairing software defects that have been released to customers. Table 4 illustrates the costs of the Team Software Process ^SM .

Factor	Cost
Training	$148,400
Development	$168,501
Total	$316,901

Now we are ready to estimate the complete costs of using the Team Software Process ^SM to help produce 10,000 lines of code. Add $148,400 for training and $168,501 in software development costs. The complete cost to use the Team Software Process ^SM to help produce 10,000 lines of code is $316,901.

Remember that use of the Team Software Process ^SM requires training in the Personal Software Process ^SM first. Therefore, the training costs also include the Personal Software Process ^SM training costs as well.
