Combination of software development effort prediction intervals: why, when and how?

  title={Combination of software development effort prediction intervals: why, when and how?},
  author={Magne J\orgensen and Kjetil Mol\okken-\Ostvold},
The uncertainty of a software development effort estimate may be described through a prediction interval, e.g., that the most likely use of effort is 1.500 work-hours and that it is 90 % probable (90% confidence level) that the actual use of effort will be between 1.000 (minimum) and 2.000 (maximum) work-hours. Previous studies suggest that software development effort prediction intervals are, on average, much too narrow to reflect high confidence levels, i.e., the uncertainty is under… CONTINUE READING
