Measurement and Analysis in Capability Maturity Model Integration Models and Software Process Improvement1 This section focuses on "Software Metrics" of Software Engineering. Software metrics can be classified into two types as follows: 1. Internal metrics: Internal metrics are the metrics used for measuring properties that are viewed to be of greater importance to a software developer. 2. A software development project is an experiment that is based on a number of assumptions theories and estimates. Quality and reliability of software. Technical work in software engineering begins with the creation of the analysis model. Three user inputs—password, panic button, and activate/deactivate—are shown in the figure along with two inquires—zone inquiry and sensor inquiry. A well defined set of requirements is the base of the MBA-SPI model. Because of the abstract nature of software and special problems with software schedule, cost, and quality, data collection and the derived metrics are an essential part of software engineering. There are five types of characteristics for a system. Count number of inputs and output, user interactions, external interfaces, files used.
