A study of requirements engineering practices among software developers at UUM Information Technology (UUMIT)

Requirements Engineering (RE) is a systemic and integrated process of eliciting, elaborating, negotiating, validating and managing the requirements of a system in software development project. UUM has been supported by various systems in academic, administrative, students’ affair and many others. Most of the current systems are developed and maintained by the Information Technology Department (UUMIT). The aim of this study is to review the current requirements engineering practices and proposing requirements engineering practices during software development at UUMIT. The outsourcing of software development is rapidly growing because of its allied benefits in the limited resources of the organizations. The main problem that is discussed in this research is the lack of studies that support software development activities at the Information Technology department (UUMIT). The study used quantitative methodology and systematic literature review to answer research questions. The main significance of this study is helping educational institutes to produce quality software development and saving cost and time by implementing requirements engineering practices. In addition to that, the study contributes to UUM by identifying the activity needed for software development so that the management is able to allocate budget to provide adequate and precise training as well as seminars for the software developers. The researcher investigated three variables; Requirements Description, Requirements Development (Requirements Elicitation, Requirements Analysis and Negotiation, Requirements Validation), and Requirement Management. The results from the survey showed that the current practice of requirement engineering in IT department of UUM is encouraging, but need for further development because most of RE practices associated with requirement development and requirement management are achieved on a regular basis and not frequently. The researcher recommended providing effective training programs for UUMIT staffs on RE practices and increases their understanding on system requirements using RE practices to develop better systems for the university. Further investigation is required in the future to understand the effect of other RE practices on software developmen

A framework for software requirement ambiguity avoidance

This research deals with software requirements ambiguity problems. Among these are incomplete, incorrect, improper, inaccurate and unambiguous requirements. Interestingly, published material related to Software Requirements Specifications (SRS) problems discusses ambiguity as one of the most conversed problems. This paper proposes a Software Requirement Ambiguity Avoidance Framework (SRAAF) to assist and support requirement engineers to write unambiguous requirements, by selecting correct elicitation technique based on the evaluation of various attributes and by applying the W6H technique. We explored existing theories and the outcomes of experimental research to construct the framework. On the basis of existing and inferred knowledge, we tried to justify proposed frameworks components. Our selection process focuses on various situational attributes. We added various situational attributes related to project, stakeholders and requirement engineer for the selection process. Newly devised approach chooses techniques other than traditional techniques or most common techniques and deals with ambiguity to capture the correct requirements information from stakeholders. The framework will be able to address the selection and ambiguity issues in a more effective way and can handle vagueness. New evidence related to attributes and adequacy matrix can be easily added to the framework without any inconvenience

Enterprise risk arising from legacy production systems: a probabilistic perspective

The model of estimation of effective minimization of strategic risks arising at modernization of the software of legacy production systems is presented. It is shown that incompatible hypotheses of strategic risks of the enterprise in the digital economy form a complete group of pairwise incompatible independent events, and their probabilities are found by mathematical methods of processing an inversely symmetric matrix, made by experts in pairwise comparison on a 5-point scale of relative importance errors of calculations of the constructed matrix (no more than 15 %). For these matrices, solutions of characteristic equations are found to determine the maximum values of the eigenvalues of matrices, which appear in the assessment of the adequacy of composite expert matrices together with the corresponding orders of matrices. To substantiate the statistical measurement under the condition of quantitative or qualitative assessment of the risk of occurrence of events, the a priori value of the probabilities of occurrence of risk in the occurrence of events is taken. The full probability formula is the formula for the probability of occurrence of an event of effective minimization of strategic risks. It is shown that to determine the a priori values of conditional probabilities of hypotheses of effective minimization of strategic risks of the enterprise it is necessary to make statistically significant sections of these hypotheses at selected enterprises for several periods, which may be subject to statistical distribution laws. Thus, the presented model for quantitative measurement, comprehensive analysis of the level of software modernization of legacy production systems of the enterprise is the initial theoretical basis for improving the system of strategic management of the enterprise in terms of digitalization
