Group maturity, team efficiency, and team effectiveness in software development: A case study in a CMMI‐DEV Level 5 organization

Abstract

Group aspects are essential to the success of software projects; however, almost no research regarding group maturity in CMMI‐DEV Level 5 organizations has been conducted. The objective of this work is to investigate group maturity and its relationship to the efficiency and effectiveness of Agile Software Development teams in a CMMI‐DEV Level 5 organization. A case study was conducted, and three data collection methods were used: a validated questionnaire was given to nine agile software teams (59 people) to measure specific aspects of group maturity, team efficiency, and team effectiveness; the effort to develop Use Case Points and a group rate (related to productivity and salary) were collected to investigate team efficiency, and focus group sessions and semi‐structured interviews were conducted with project managers and team leaders to explore group issues in software development. Aspects of group maturity were correlated with team effectiveness and team efficiency measures. Communication was found to be strongly correlated with team effectiveness and group rate, and conformity and the clarity of roles and goals were found to be strongly correlated with team efficiency. The results suggest that group maturity has a positive influence on software teams in CMMI‐DEV Level 5 organizations.

Behavioral Model of Business Change Management in Relation to Building Competitiveness in Market Economy Conditions

“…We can identify the bridging of this step into the marketing area in such a way that the company does not make an effort to map the interest of consumers in its products and at the same time does not document the information that would serve as a basis for further activities of the company in the future. The second step of this model is presented as a repeatable level, in which elements and techniques of project management are already beginning to appear and the success of the process is perceived as repeatable, based on a more advanced perception of processes compared to the first level (Ramirez-Mora et al, 2020). Business processes are predefined and subsequently documented.…”

“…The fourth level of the CMMI model is the level managed and within it the company monitors and controls its own processes based on careful data collection and analysis. In this case, quantitative data are used, with the basic aim of identifying predictable processes that will be in line with the needs of stakeholders (Ramirez-Mora et al, 2020).…”

“…One of the expected outcomes of an engineering student is working in multidisciplinary teams [15]. Companies also require communication, continuous learning, leadership, teamwork, and innovation [16][17][18]. The project's success or failure in software engineering courses is related to the collaboration between team members [19][20][21].…”
