Abstract

Agile software development has evolved in the past two decades into a set of tools for developing software. It is based on "all at once" models that assume that the creation of software is done by simultaneously working on requirements, analysis, design, coding, and testing, then delivering the entire system all at once. Agile main principle is using an iterative and incremental approach to building software. In Agile practice most of the responsibility is on the hands of the team members that need to estimate the work within iteration and commit to it. In order to accomplish this today, team members use their experience, educated advice, and some rules of thumb. We believe that especially in this stressed environment with almost ?microscopic? work assignments, there should be a simple and fast mathematical model that assists them in this task. The model should handle dynamic environments and risky situations. This paper presents such a model, called HRA, and demonstrate in on a simple but representative real scenario.
