18.1 Software Inspection Process


15.6 Capability Maturity Model Integration

The benefits of using Capability Maturity Model Integration to help produce 10,000 lines of code are $3,023,064. This was obtained by subtracting $1,486,933 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 consist of process, product, preparation, assessment, and inspection costs. The special costs to use Capability Maturity Model Integration are $541,300, $400,400, $48,000, $47,700, and $70,833, respectively. This totals $1,108,233 to introduce Capability Maturity Model Integration as a SPI method.

The development cost of $254,400, testing cost of $195,000, and maintenance cost of $966,700 were not included as special costs. The development, testing, and maintenance costs either stayed the same or decreased. Had the development, testing, or maintenance costs increased, the differences or the increases would have been included. Table 19 illustrates the B/CR of Capability Maturity Model Integration .

Now we are ready to determine the B/CR of Capability Maturity Model Integration to help produce 10,000 lines of code. Divide the benefits of $3,023,064 by the costs of $1,108,233 for Capability Maturity Model Integration . The B/CR of using Capability Maturity Model Integration to help produce 10,000 lines of code is 3:1.
