Purpose
– The purpose of this paper is to propose Knowledge4Scrum, a novel knowledge management tool for agile distributed teams. Agile software development (ASD) refers to a group of software development methodologies based on iterative development, where requirements and solutions evolve through collaboration between self-organizing cross-functional teams. The two most widely used methodologies based on the agile philosophy are scrum and extreme programming. Whichever methodology is considered, agile teams usually consist of few members and are collocated under the same roof. However, nowadays, agile practices for distributed development are gaining much momentum. The main reasons behind such practice are cheaper skilled labour, minimizing production cost, reducing time to market and increasing the quality and performance of projects. Along with the benefits obtained through globally distributed development, there are, however, many difficulties faced by various organisations. These problems are caused mostly due to distance, time and cultural differences. To meet up with the level of complexity of projects, ASD also has to keep up with many challenges, especially in cases of distributed teams. Four major challenges have been identified. First, the introduction of global software development entails a number of difficulties, especially related to knowledge sharing. For instance, lack of transparency is frequently observed within such teams, whereby a team member is totally unaware of the activities of his/her colleagues. Second, the unavailability of team members due to time zone differences adds up to the list of problems confronted by distributed teams. Third, there can be misunderstanding amongst the team member due to communication problems, especially in cases where the mother language of the team members is different. Fourth, a common issue faced by distributed teams is the loss of knowledge when an employee resigns from his/her post.
Design/methodology/approach
– Based on the main problems outlined above, what has been proposed is Knowledge4Scrum, a novel knowledge management tool for agile distributed teams. Knowledge4Scrum will act as a global repository for knowledge sharing in Scrum distributed teams with the possibility of creating new knowledge through data mining techniques. Valid past projects data have been collected to train and test the data mining models. The research also investigates the suitability of knowledge management in Scrum distributed teams to address the various challenges addressed above.
Findings
– Knowledge4Scrum supports the four knowledge management processes, namely, knowledge creation/acquisition, knowledge storage, knowledge dissemination and knowledge application. It has been found that the aforementioned tool satisfactorily addressed issues of distance, time and cultural differences that crop-up in distributed development teams. Data mining has been the main aspect for the knowledge creation and application processes, whereby new knowledge has been determined by examining and extracting patterns from existing data found in the repository.
Originality/value
– A major feature of the Knowledge4Scrum tool lies in the knowledge creation and application section, where a number of data mining techniques have been utilised to identify trends and patterns in past data collected. When compared to the COnstructive COst MOdel to estimate project duration, Knowledge4Scrum gives more than satisfactory results. Such functionalities will actually help managers for future project planning and in decision-making.
