Distribution Comparisons of EAC Cost Growth for Aircraft Work Breakdown Structure Elements

In this study, the authors analyze probability distributional fits to Estimate at Completion cost growth for various Work Breakdown Structure elements. Results suggest either the lognormal or Weibull as best fits and a possible underestimating of the Coefficients of Variance and 85th percentiles in a program’s budget.

Abstract

In this study, the authors analyze probability distributional fits to Estimate at Completion cost growth for various Work Breakdown Structure elements. Results suggest either the lognormal or Weibull as best fits and a possible underestimating of the Coefficients of Variance and 85th percentiles in a program’s budget.
