Many important aspects of the education process are known unknowns (Secules & Groen-McCall, 2019; Secules & McCall, 2019): a student's thoughts and feelings, mental health and other aspects of the private self, and a range of past experiences that impact the current moment. Reliability - extent to which a program is supposed to perform its function with the required precision. For certain items this is relatively easy to define, for example a ship's anchor has the function of holding a ship at a given location. However, there are several differences between the two models as follows : Barry W. Boehm Software Quality Model (1978)¶ The Boehm software quality model attempts to quantify software quality through a series of attribute indicators. 18.1 Basic Idea in Software Process. Mccall's Quality Factor 2. McCall's model was developed by the Rome air development center (RADC), the US air-force electronic system decision (ESD), general electric, in order to improve the quality of software products at software development companies.The model was developed to assess the relationships between external factors and product quality criteria. These factors help in providing a better user experience.

For each quality factor McCall defined one or more quality criteria (a way of measurement), in this way an overall quality assessment could be made of a given software product by evaluating the criteria for each factor. Other challenging aspects include power relations and patterns of . Measuring those factors tell us where we need improvement. The 11 factors are actually grouped right in to 3 classifications - item procedure, item modification, as well as item shift factors. The eleven factors a re grouped into three categories - product operation, product revision, and product transition. Below are few quality models from the so called Quality Management Gurus. Quality Criteria (To build): They describe the internal view of the software, as seen by the developer. He has categorized the software quality into 3 categories. For software products, the fitness of use is generally explained in terms of satisfaction of the requirements laid down in the SRS document.
