SOFTWARE QUALITY ASSESSMENT SCENARIO MODEL

Laptov Denis Sergeevich

Software quality assessment is a mandatory process when ensuring the necessary quality of software as part of the overall process of its development. The constant development of existing and the emergence of new information technologies (artificial intelligence, cloud computing, virtual and augmented reality, etc.) and systems increases the requirements for the evaluation process and software quality. Existing approaches to quality assessment have significant drawbacks associated with weak formalization when planning software quality assessment tasks, a high degree of uncertainty when making decisions by responsible process participants, insufficient or redundant information, determining the number of participants in the software evaluation process. Recent open access publications were reviewed, which consider the scenario approach in general and in terms of evaluating individual software quality tasks. Highlighting unexplored parts of a common problem. Description of a scenario approach for software quality assessment tasks. A more formalized representation of the scenario approach to solving software quality assessment problems was not considered. The purpose of the article is to develop a scenario model for software quality assessment. The article offers a presentation and description of a software quality assessment scenario model consisting of the following 6 elements: initial conditions, input data, actions, transitional data, roles and results. It was found that during its life cycle, a script can be in the following states: a script on paper, a pilot script and a real scenario. During the transition to each state, many elements of the scenario may change. To formalize such changes, additional script operations were introduced and formally described: the exclusion operation and the inclusion operation. Variants of inequalities of a set of scenario elements for a paper scenario and a pilot scenario are considered. The presented model of the software quality assessment scenario can be used in software quality assessment based on defect seeding.
