A Multicriteria Approach to Support Task Allocation in Projects of Distributed Software Development

Organizations are increasingly investing in Distributed Software Development (DSD) over the years. A typical decision-making problem in the distributed scenario consists of deciding which team should be allocated each task. That decision takes into account a relative degree of subjectivity. That setting is suitable for applying Verbal Decision Analysis (VDA). This paper introduces an approach to support the allocation of tasks to distributed units in DSD projects, structured on the hybridisation of methods of Verbal Decision Analysis for classification and rank ordering applied to influencing factors and executing units. Firstly, a review of the literature was conducted aiming to identify the approaches to support the allocation of tasks in DSD contexts. Then, an approach was developed by applying VDA-based methods for classification and ordering. Bibliographic research and the application of surveys with professionals allowed identifying and characterising the main elements that influence task assignment in DSD projects. Afterwards, experiences were carried out in five real-world companies. In the end, the proposed approach has been submitted to the evaluation by the professionals of the participating companies and by some project management experts. The proposed approach comprises a workflow containing responsible actors and descriptions of the activities. Automated tools are also employed in automating the implementation of the approach. After applying the approach in five companies, task assignment recommendations are presented in groups for each company, according to the task type, i.e., requirements, architecture, coding, and testing, ranging from the most to the least preferable office. Results of the experiences and evaluations held during this work present evidence that the proposed approach is flexible, adaptable, and easy to understand and to use. Moreover, it helps to reduce decision subjectivity and to think of new aspects, supporting the task allocation process in DSD.

“…The rank column indicates the position of the influencing factor on the preference scale generated by the model. For example, for requirement-related tasks, Factors 2,4,5,6,7,11,13,14, and 15 were ranked at position 1; after all, they all have the best representation, i.e., A1B1C1.…”

Task assignment to distributed teams aided by a hybrid methodology of verbal decision analysis

An increasingly common practice in large software development companies is to distribute tasks among geographically dispersed teams. This practice can bring many benefits, such as gains in terms of time and cost, but many are the challenges. One of the major challenges regards the method of assigning tasks to remote teams. This method involves knowing, classifying and ordering the factors that drive the assignment of tasks in a distributed scenario. This is a typical scenario for decision-making based on multiple criteria. Verbal decision analysis (VDA) is a multi-criteria framework to decisionmaking. This study presents a hybrid methodology structured on methods of VDA for classification ORdinal CLASSification (ORCLASS) and ordering (ZAPROS III-i) of factors that drive task assignment to distributed teams in software development projects. Tasks were grouped according to their type, i.e. requirements, architecture, implementation, and testing.

Analysis of task allocation in distributed software development through a hybrid methodology of verbal decision analysis

The management of distributed software development projects presents many challenges. One of them happens right at the start of the project and consists of the allocation of tasks between remote teams. When allocating a task to a site, the project manager takes into account several factors such as technical knowledge of staff and proximity to the client. The project manager usually takes this decision in a subjective way. The verbal decision analysis is an approach based on solving problems through multicriteria qualitative analysis, which means it considers the analysis of subjective criteria. This paper describes the application of verbal decision analysis methods ORdinal CLASSification and ZAPROS III-i to classify and rank the most relevant factors that the project managers should take into account when allocating tasks in projects of distributed software development. KEYWORDSdistributed software development, multi-criteria decision analysis, ORCLASS Method, task allocation, verbal decision analysis, ZAPROS III-i method | INTRODUCTIONThe distributed software development (DSD) is a reality more and more present in modern companies. The perspective to expand the workforce capacity, the conquest of new markets, and the cost reduction possibility are some of the reasons that make software development companies adopt distributed development.1 On the other hand, the distribution brings many challenges, such as language and time zone differences and increased complexity of coordinating and controlling the project. 2 In this context, the allocation of tasks is an even more critical activity for project planning because of the distribution. 3 The distribution of tasks to remote teams can be seen as a fundamental activity for the success of a distributed project.However, this activity is still a major challenge in global software development due to limited understanding of the factors that influence task allocation decisions.4Deciding which task we should allocate for each team is typically a decision-making problem. Routinely, the project manager makes this decision based on their experience and knowledge about the project and the teams involved. We mean that a high degree of subjectivity is present in the decision-making process. This is an appropriate setting for verbal decision analysis (VDA), which consists of an approach based on multicriteria problem solving through its qualitative analysis, 5 ie, VDA methods take into consideration the criteria's subjectivity.This paper describes the application of a hybrid methodology using VDA methods to classify and rank order the most relevant factors to be considered by project managers when allocating tasks in distributed software development projects. First, expert interviews were conducted to identify the criteria and the criteria values. Then, a questionnaire was applied to a group of project managers to characterize each factor through the criteria and criteria values. Next, the ORdinal CLASSification (ORCLASS) method was applied to divide the factors into pref...
