User Centered Non-Functional Requirements Specification – An Extended Use-Case Diagram

Requirements Engineering (RE) activity is often initiated with vaguely specified software requirements. The ambiguities must be overcome to the extent possible when the requirements are specified. Both functional (FRs) and non-functional (NFRs) requirements should be correctly and unambiguously specified. Users communicate about the NFRs in informal discussions. Requirements engineers use formal or semi-formal language notations to manually convey the NFRs. A laborious and ineffective manual approach, however, is unable to identify all likely NFRs and resolve ambiguities in those NFRs. This paper discusses an approach that attempts to overcome ambiguities from natural language requirements, recognize NFRs, and generate NFR specification through the extended Unified Modelling Language (UML) viz. use-case diagram. The empirical evaluation of the proposed approach on the PROMISE dataset achieves an average result of 79.76% recall, 90.05% precision, and 84.59% F-measure. The proposed approach allows the requirements analyst to semi-automatically recognize NFRs and visualize them using an extended use-case diagram at an early stage of RE.

COUNSELING MODEL BASED ON BACKWARD CHAINING OF STUDENT BEHAVIOR AT SMK 10 MUHAMMADIYAH KISARAN

Student development includes conduct as a key component. Student behavior becomes crucial in deciding how successful students will be in different spheres of life. The variety of student behavior can hinder the learning process and personal development of students. Through the development of an expert system-based counseling model based on backward chaining, this study seeks to discover trends in student behavior. The research process starts with problem analysis, goal setting, literature study, data collection, system design and implementation, and results analysis. It then moves on to counseling model development and implementation in the school setting. To determine the reasons for the unruly behavior of the kids, data were analyzed using a backward chaining methodology. UML Usecase diagrams are used in system design to define the roles of actors and users. The established counseling model, which consists of 14 behaviors, 67 phenomena/symptoms, and 14 rules, focuses on goals and methods to modify student behavior. Three students underwent system testing based on previously achieved goals from therapy. The findings revealed "Smoking," "Emotional Problems," and "Fighting" among the student behaviors. When the Backward Chaining-based counseling model is used, it is simpler for homeroom teachers to gather information about students' conduct from them and to offer remedies based on the transfer of professional knowledge without having to wait for the counselor guidance procedure

VERBAL DESCRIPTION OF THE TECHNOLOGY FOR PLANNING THE QUALITY IMPROVEMENT OF A SUBSET OF THE PROCESSES OF THE SPICE MATURITY REFERENCE MODEL

It is noted that to solve the problem of developing information technology for planning the increase of maturity level of a subset of the processes of the SPICE reference maturity model, this issue must first be considered at the verbal level as a technology (sequence of stages) for the implementation of the given problem. At the first stage, the structure of the SPICE reference model, which consists of a number of separate processes, was formalized. This set is presented as a hierarchical structure: the first level is a set of processes and subprocesses; the second level is a set of process groups; the third level is a set of process categories. At the second stage, the method of assessing the level of possibility of a separate process/sub-process of the reference maturity model SPICE is considered. It is given from the point of view of two dimensions of the SPICE model: the purpose of the processes; the attributes of the processes (measurable characteristics necessary for managing the process and increasing the possibility of its execution). The third stage of the technology is focused on the synthesis of planning model of the subset development processes for the SPICE model, which determines the quality level of a separate component of the software development process (SDP), which in turn has a positive effect on the level of development of software systems. Assessment and planning of the possibility level of a subset of processes is implemented during a certain planning period under conditions of limited resources based on their optimal distribution, taking into account the importance of individual processes and their practices during the planning period. At the fourth stage of the technology, an algorithm for planning the development of a subset of processes of the reference maturity model SPICE is considered based on the method of sequential analysis of options. This is primarily due to the fact that the optimization model has an additive objective function. The method allows discarding those appropriate solutions that do not contain optimal solutions. In the future, when specifying the model, it is planned to choose an algorithm that belongs to this method and adapt it to the solution of the given problem. The fifth stage is devoted to information technology implementation of the developed model and algorithm. At this stage, the following set of problems is solved. Analysis of business processes of the technology of improving the quality of software development process. Definition of software requirements. Forming a diagram of use cases. Development of data models. Justification of the choice of tools for software development. Selection of reference system architecture. Next, software coding and testing. At the sixth stage, based on information technology, a number of variants of the plan for improving the quality of a subset of the processes of the SPICE maturity model are formed in order to support decision-making by the management of the IT company. For this, a set of effective solutions is preliminarily determined, which is proposed to determine the final option, which is implemented later.
