An Intelligent Recommender and Decision Support System (IRDSS) for Effective Management of Software Projects

Abstract

The management and estimation of agile projects are challenging tasks for software companies due to their high failure rates. This paper emphasizes how to improve management and estimation challenges in the context of scrum, which is an agile process widely used for the development of small to medium size software projects. The scrum emphasis on code results in spending inadequate time on the estimation process. Mostly, the scrum master, along with the scrum team, estimates the upcoming software projects based on experience or historical data. Many issues can arise in a case where expert judgment is not available or historical data are not properly organized. In this paper, an Intelligent Recommender and Decision Support System (IRDSS) is proposed that can help the scrum master to better estimate an upcoming software project in terms of cost, time, and recommendations of human resources. Formal specification of IRDSS is also performed using the formalism known as Z language. Furthermore, an experiment on fifteen web projects was performed to validate the proposed approach and compared it with Delphi and Planning Poker estimation methods. The overall results indicate that the proposed system can produce better estimation than Planning Poker and Delphi methods by applying MMRE and PRED evaluation. This research opens new directions for the scrum community for the development of software projects within the allocated time and cost.

External technology acquisition, exploitation and process innovation performance in emerging market small and medium sized enterprises: the moderating role of organizational slack

“…Third, the software industry is currently playing an essential role in many areas of the global economy (Pedroso and Oliveira, 2013), it is growing rapidly, and is of increasing importance in achieving international competitiveness by other high-technology industries as well as the relevant country's national economy (Zhao et al , 2009). However, despite its importance, software development projects still have a high failure rate (Hamid et al , 2020; Jiang et al , 2004; Kim et al , 2018; Lauesen, 2020; Pospieszny et al , 2018). Industry experts point to the software development process as one of the main factors contributing to the success or failure of software product development (Kaur and Sengupta, 2011; Geethalakshmi and Shanmugam, 2008).…”

Rapid Digital Transformation Using Agile Methodologies for Software Development Projects

“…A variety of basic agile workflow concepts are outlined in this manifesto. This manifesto emphasizes iterative and gradual growth, client collaboration, regular and rapid implementation, a shorter development time, customer loyalty, lower mistakes, and adaptability to agile improvements [8,9,10].…”

Prediction based cost estimation technique in agile development

“…less empirical support for accuracy. This method cannot be used to make predictions [32][33][34][35].…”
