Item A SYSTEMATIC MAPPING ON THE QUALITY AND UNDERSTANDABILITY OF UML DIAGRAMS(2022-01-10) TABRIZI, SINA ALIZADEH TABRIZI; Cagiltay, Nergiz Ercil; Topallı, DamlaNowadays, the concept of quality is an integral component of any tangible and intangible product and service. In the field of software, the quality is not merely confined to the final product, but it should be applied to all phases of the software development life cycle (SDLC). The Model-driven Software Development (MDSD) necessitates the experts with high skill to fabricate quality modelling artifacts in order to deliver an authentic perception of the desired system. One of the de facto modeling languages is Unified Modelling Language (UML) which is commonly used in the sphere of software engineering to model the system’s static and dynamic behaviors, to discern the system structure and to expedite the coding and communicating with the stakeholders on the required functional and non-functional requirements. The primary objective of the present thesis is to present the state-of-the-art on the quality and understandability of UML notation. Therefore, a systematic mapping was applied on 103 journal papers extracted from Web of Science. The results indicated that quality is the main aspect in such a way that other aspects like understandability and maintainability are subsets of this aspect. According to the reviewed studies 13 factors have been found to effective on the quality and understandability, namely, diagram, diagram type, evaluation, guideline, modelling, quality assessment approach, redundancy, refactoring, representations, requirements, software engineer (identified by modelling expertise, knowledge, experience, cognitive abilities, learning style, learning motive, learning strategy) structure and testing.
