This article investigated the moderating effect of the perceived compatibility of agile methodologies in determining the actual success of a methodology. The researchers conceptualised the agile methodology perceived success by using cost, scope, time and quality to complete the project. The researchers further hypothesised that perceived compatibility has moderating effects towards agile methodology perceived success and its use. The theoretical framework was evaluated by means of data collected from IT professionals (n = 230). The objective of the study was to determine how agile methodology use and perceived compatibility influence agile methodology perceived success in South Africa. A survey was conducted among IT professionals and the results analysed using statistical methods. The results showed perceived compatibility to have a moderating effect towards agile methodology use, time and cost. Nevertheless, there was a lack of moderating effect of perceived compatibility with regard to agile methodology use and perceived quality, and agile methodology use and perceived scope. The results of this study formulate a comprehensive model that could provide a set of guidelines for agile methodology use to the agile methodology communities and other IT professionals in South Africa.
Background: The continued in failure of agile and traditional software development projects have led to the consideration, attention and dispute to critical success factors that are the aspects which are most vital to make a software engineering methodology fruitful. Although there is an increasing variety of critical success factors and methodologies, the conceptual frameworks which have causal relationship are limited.Objective: The objective of this study was to identify and provide insights into the critical success factors that influence the success of software development projects using agile methodologies in South Africa.Method: Quantitative method of collecting data was used. Data were collected in South Africa through a Web-based survey using structured questionnaires.Results: These results show that organisational factors have a great influence on performance expectancy characteristics.Conclusion: The results of this study discovered a comprehensive model that could provide guidelines to the agile community and to the agile professionals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
