share
Effort estimation plays an important role in the software development process by supporting the decision-making process for the stakeholders. DevOps has become a widely used software engineering practice with the collaboration of the development and operational teams. This paper addresses the factors that affect the effort estimation strategies and practices in DevOps based software development in Sri Lanka. This study explains the research approach, generation of the conceptual model and the quantitative data analysis process in detail. A survey is conducted among the software professionals who are working in DevOps-based software development in the Sri Lanka IT industry and a detailed data analysis is performed using statistical techniques to identify the reliability, correlation and significance of the considered factors. With an extensive analysis the independent variables namely, exploration, communication, and technology stack are identified as highly impacted factors to the effort estimation in DevOps-based software development. We also provide recommendations for the effort estimation strategies and practices; hence the managerial decision can be made for the improvements of the development process.
