Effort estimation in software development using story point: a machine learning approach

Abstract: Agile methodologies are besieged with problems and potential solutions around predictive insights on a project. These problems range from estimation, quality, to effort and duration requirements. Despite of having innumerable predictive models not a single reliable solution is available to estimate the duration and effort required to complete an agile project on an ongoing basis. This is due subjective nature of 'story point', and progressive elaboration of 'user story'. This paper analyses the relationship between story points and effort, across a sample of software development projects, in an organisation. A novel machine learning predictive model has been developed and is implemented across agile projects that infer relationship between 'effort' and 'story points', directly in contrast with agile literature. This predictive model was tested and worked accurately, reliably and effectively across various agile projects. This research can be extended to agile projects having sprints of less than fifty story points.
