Abstract:

Software development teams adopt Agile methodologies to respond to rapidly-changing business needs. In Agile Iterative Development (e.g., Scrum), a software development team plans, implements, and delivers software increments in iterations of 2-4 weeks (i.e., sprints in Scrum). During sprint planning, the team estimates the size of the work to be done to allocate just-enough workload for the short sprints. To estimate the effort, the team relies on an estimation method based on the team consensus (e.g., experts’ opinion, Planning Poker). However, such a method is prone to be inaccurate, which could lead to a waste of team effort in re-planning and huge revenue loss in the IT industry. This presentation will discuss the common reasons for inaccurate estimations, the potential impact of unreliable estimations, and suggestions for practitioners towards a reliable effort estimation and sprint planning.
