Investigation Into Engineering Change Order Costs And Appropriate Rules-Of-Thumb, Kaiana M. Miller Mar 2022

Investigation Into Engineering Change Order Costs And Appropriate Rules-Of-Thumb, Kaiana M. Miller

Theses and Dissertations

Engineering Change Orders (ECO) are technical requirements changes to existing contracts. To account for the potential increase in contract costs stemming from ECOs, current acquisition practice is to estimate a dollar value to hold in management reserve (MR) in case of ECO occurrence. Estimators often rely on rules-of-thumb when developing these estimates. Specifically, estimators use a 10% rule-of-thumb for estimating MR contract costs in the Development life cycle phase and a 5% rule-of-thumb for contracts in the Production or O&S life cycle phase. However, no empirical data supports or validates these 10% and 5% figures. Using a new data source, …
