Dromey has built a quality evaluation framework that analyzes the quality of software components through the measurement of tangible quality properties. Each artifact produced in the software life-cycle can be associated with a quality evaluation model. Dromey gives the following examples of what he means by software components for each of the different models: • Variables, functions, statements, etc. can be considered components of the Implementation model; • A requirement can be considered a component of the requirements model; • A module can be considered a component of the design model; According to Dromey, all these components possess intrinsic properties that can be classified into four ca...
