Inaccurate estimates of software development effort is a frequently reported cause of IT-project failures. We report results from a study that investigated the effect of introducing lessons-learned sessions on estimation accuracy and the assessment of uncertainty. Twenty software professionals were randomly allocated to a Learning group or a Control group(More)
To enable properly sized software projects budgets and plans it is important to be able to assess the uncertainty of the estimates of most likely effort required to complete the projects. Previous studies show that software professionals tend to be too optimistic about the uncertainty of their effort estimates. This paper reports the results from a(More)
Previous studies report that software developers are over-confident in the accuracy of their effort estimates. <b>Aim:</b> This study investigates the role of outcome feedback, that is, feedback about the discrepancy between the estimated and the actual effort, in improving the uncertainty assessments. <b>Method:</b> We conducted two in-depth empirical(More)
This research abstract describes my proposed doctorial work within the field of software project cost and effort estimation. My work focuses on assessment of uncertainty of software development cost or effort estimates. In particular, the work focuses on to which degree this assessment is a skill that can be improved with better training. Work completed(More)
