12.6 CMMI Breakeven Point Methodology


12.2 CMMI Benefit Methodology

The benefit methodology for Capability Maturity Model Integration is a procedure to measure, quantify, and analyze the amount of money returned. Capability Maturity Model Integration results in higher productivity and quality, resulting in lower development and maintenance costs. Benefit is the economic value of using Capability Maturity Model Integration to create a new and improved software process. Its benefit methodology is a three-part process that consists of estimating test costs, total life cycle costs of testing, and benefits. Its benefit methodology consists of a variety of defect models used in combination. Key elements include the test cost model and the total life cycle cost model. Some of the benefits are due to increased productivity, resulting in up to a 50% decrease in software development costs. Increased productivity is factored into the total life cycle cost model. The test and total life cycle cost models are used to compare the total life cycle costs of software testing to those of the Capability Maturity Model Integration . Figure 62 illustrates the benefit methodology for Capability Maturity Model Integration .

Estimate test cost (baseline) for CMMI : The objective of this activity is to estimate the cost of removing the maximum number of software defects using software testing. This substep includes: estimate post-test defects (baseline) for CMMI and estimate baseline test cost ( projected ) for CMMI .

Estimate total life cycle cost (test) for CMMI : The objective of this activity is to estimate software development and maintenance costs associated with using software testing. This substep includes: estimate total software cost (test) for CMMI , estimate total test cost (test) for CMMI , and subtract total test from software cost for CMMI .

Estimate benefits (projected) for CMMI : The objective of this activity is to compare software development and maintenance costs of testing and CMMI . This substep includes: subtract total life cycle cost of CMMI from test for CMMI .
