• W2966730951 abstract "Software is developed based on the requirements of users which are obtained duringthe requirements gathering activity in the requirement engineering process in softwaredevelopment projects. The aim is to collect complete and unambiguous requirements.Nevertheless, not all projects are free from requirement changes or requirementsvolatility which involves additions, deletions, and modifications of requirements.Frequent changes to requirements are a risk factor in software development projects.Moreover, software is developed based on human activities such as problem solving,analytical thinking, communication and cognitive reasoning. Although technical skillis important to a software project’s successful outcome, the human factor is adetermining issue that affects most software projects. Thus, human factors are amongthe main challenges in requirements engineering including requirements volatility.Human as main part for software requirements gathering have an important role onrequirements volatility. Changes in software requirements occur through the role ofhuman in requirements gathering. However studies on human factors in requirementsvolatility are still lacking. Most of the studies have addressed the technical aspects ofrequirements gathering and requirements volatility in relation to productivity,software defects, and software release. A few studies focus on the factors thatinfluence requirements volatility involving communication between users anddevelopers, and defined the methodology for requirements analysis and modelling.Despite the maturity of human factors in many contexts, very little published literaturediscusses about human factors and requirements volatility. In this research, a humanfactors model on requirements volatility named as HF-RV model, is proposed. Theconstructs of the human factors model are human errors, moral capital, spiritualcapital, human capital and human ability. The human factors model is derived fromanalysis of related literature in human factors theories which include personalitytheories and human errors theories. The model then had undergone furtherinvestigation to identify the relationships between human factors and requirementsvolatility by surveying two hundred fifteen experienced participants in requirements gathering. The data collected from the survey was analysed using SPSS and AMOSfor structural equation modelling and other analysis. The results indicatedconsiderable confirmatory for hypothesized model. Furthermore, Exploratory FactorAnalysis, Confirmatory Factor Analysis, test for reliability and validity, and model fittest conducted show the model is acceptable. To gain more insight on usefulness ofthe model, opinion from experts were gathered through interview sessions. The resultsfrom this research reveal the significant impact of human error, moral capital, humancapital and human ability on requirements volatility. However, spiritual capital impacton requirements volatility is statistically rejected. In short, it provides new insight intoimpact of human factors on requirements volatility in requirements gathering." @default.
