Engineering Change Orders In Space Programs: "What Are The Odds?", Aaron Noel D. Santos
Theses and Dissertations
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 …

Salvaging Value From The Measure Of "Requirements Volatility" In The Dod's Software Resources Data Report (Srdr), Robert T. Walker

The DoD and the software development industry as a whole has long dwelt over the idea of requirements volatility (RV). The DoD has toiled with this concept so much so that its guidance was modified four times over a 13 year span. In these changes, its policy completely transformed the what, how, and when regarding RV information. As a result, the volatility data it has received is quite varied and seemingly useless for anything more than anecdotal analysis. This study takes several approaches to salvage value from this data. It begins with a survey of the uncertain concept of volatility, …
