Detailed explanation-1: -The size estimate for a software product to be built must be based on a direct measure like LOC. The correct answer is ‘False’.
Detailed explanation-2: -Historically, the most common software sizing methodology has been counting the lines of code written in the application source. Another approach is to do Functional Size Measurement, to express the functionality size as a number by performing function point analysis. The original sizing method is the IFPUG.
Detailed explanation-3: -The project size is a measure of the problem complexity in terms of the effort and time required to develop the product. Currently two metrics are popularly being used widely to estimate size: lines of code (LOC) and function point (FP).
Detailed explanation-4: -The LOC (Line of Code) is a product size metric in software engineering. Here, the number of lines in the code are counted and based on the number of lines the cost is calculated.
Detailed explanation-5: -There are two basic models for estimating software development effort (or cost): holistic and activity-based. The single biggest cost driver in either model is the estimated project size.
