Abstract: The problem of business reliance on expert judgement is solved through charge number coding with an added code line for the complexity or work difficulty (a ‘complexity factor’). A complete charge number code provides the means to automate many business functions that are traditionally conducted through expert judgment. The primary purpose of the charge number code with Complexity Factor is to automate or assist in cost and schedule estimating. The use of a Complexity Factor in stored performance information provides the additional means for automating many Program Management, Business Development Management, and Personnel Management functions. These functions include personnel projections, scheduling, and assessment, program performance reporting, and Work Breakdown Structure (WBS) creation. The complete charge number code also provides the means for data navigation through the System and an integrated Business and Program Information Systems.
