Abstract

Effort and time estimation at the initial stage of an agile project is a difficult and challenging task due to volatility and changing in customer requirements. Scrum remains the most used agile project management method. However effort estimation in scrum is mainly based on story points which are subjective measures and mostly lead to inaccurate estimates. In this paper we propose to adjust this measure using three adjustment factors. Moreover this paper will show how to use also this adjusted story point in velocity calculation to ameliorate scrum time estimation.
