Engineering Change Orders in Space Programs: What Are The Odds?

Abstract

There has been little empirical evidence and vague official guidance published to inform the Department of Defense (DOD)acquisition community on the cost growth effects of engineering change orders (ECO) on their programs. The information is especially scarce when it comes to understanding those effects in space programs. Utilizing previous research to our advantage, we explore factors that may explain ECO-related cost growth including program size, acquisition phase, the number of modifications to a contract, contract type, and specific space commodity assets. Using non-parametric analysis, contingency tables, and odds ratio tests, these were found to be significant factors (except acquisition phase) that could determine the likelihood of ECO-related growth at different percentage levels. This research aims to establish a reference point for future research into ECO-related cost growth and space commodities
