| dc.description.abstract | In responding to the dynamic business
environments, most software development
organizations have shifted towards the practice
of agile methodologies, due to their capability in
undertaking change in requirements. Accurate
and reliable effort estimates usually assist
effective project planning. Effort estimation in
agile software development differs from
traditional approaches due its iterative nature. In
this survey-based study, the main objective is to
assess the status of effort estimation by agile
software development teams in Sri Lanka. Hence,
the investigation focuses on finding out the
widely adopted agile effort estimation
techniques, effort predictors, accuracy level of
each technique, and the factors affecting
estimation accuracy. The data was collected from
software industry professionals using an online
questionnaire and was statistically analysed.
According to the results obtained, “Expert
Judgment”, “Planning poker”, and “Use Case
point” are the most used effort estimation
techniques among Sri Lankan agile teams, and it
was evident that “Expert Judgment” is the most
accurate effort estimation technique among
them. Further, a conceptual model on the effect of
cost drivers on the accuracy of the effort
estimation was proposed based on the results of
correlation and linear regression analysis. | en_US |
