The special, new, or additional costs required use the Software Inspection Process to produce 10,000 lines of code are $82,073. This is obtained by adding the training and inspection costs of $11,240 and $70,833.
The special, new, or additional costs required use the Personal Software Process SM to produce 10,000 lines of code are $105,600. This is obtained by using only the training cost of $105,600.
The special, new, or additional costs required use the Team Software Process SM to produce 10,000 lines of code are $148,400. This is obtained by using only the training cost of $148,400.
The special, new, or additional costs required to use the Software Capability Maturity Model to produce 10,000 lines are $311,433. This is obtained by adding the process, product, preparation, assessment, and inspection costs. The costs are $56,100, $117,600, $36,800, $30,100, and $70,833, respectively.
The special, new, or additional costs required use ISO 9001 to produce 10,000 lines of code are $173,000. This is obtained by adding the process, product, preparation, and audit costs. The costs are $54,600, $56,000, $26,400, and $36,000, respectively.
The special, new, or additional costs required to use Capability Maturity Model Integration to produce 10,000 lines of code are $1,108,233. This is obtained by adding the process, product, preparation, assessment, and inspection costs. The costs are $541,300, $400,400, $48,000, $47,700, and $70,833, respectively. (The assessment costs are for one four-person software project.) Table 38 illustrates the analysis of costs.
SPI Method | Cost | Cost/Person | Normalized |
---|---|---|---|
Inspection | $82,073 | $20,518 | 1.00 |
Personal Software Process SM | $105,600 | $26,400 | 0.98 |
Team Software Process SM | $148,400 | $37,100 | 0.94 |
Software Capability Maturity Model | $311,433 | $77,858 | 0.79 |
ISO 9001 | $173,000 | $43,250 | 0.92 |
Capability Maturity Model Integration | $1,108,233 | $277,058 | 0.07 |
The least expensive SPI method is the Software Inspection Process at $82,073. The most expensive SPI method is Capability Maturity Model Integration at $1,108,233. Cost per person ranges from $20,518 for the Software Inspection Process to $277,058 for Capability Maturity Model Integration .
The Software Inspection Process, Personal Software Process SM , Team Software Process SM , and ISO 9001 have the lowest special costs. This is on a normalized scale. Capability Maturity Model Integration has the highest special cost on a normalized scale.
