This investigative study demonstrated the benefits of addressing human considerations during the system development life cycle in order to have had long-term benefits to program managers and systems engineers. The approach was to use a retrospective content analysis of documents from weapon system acquisition programs, namely Major Defense Acquisition Programs, in order to seek the presence of terminology relating to Human Systems Integration. There is only a small amount of published research to date on the relationship between program documents that included terminology relating to Human Systems Integration and any eventual cost change or schedule change for Department of Defense weapon systems. Binary logistic regression analyses were conducted to investigate the effect of the presence of words relating to Human Systems Integration on the success of programs. The presence of terminology about human factors engineering, habitability, and survivability in a weapon system acquisition program’s documents was a good indicator that schedule slippages and cost overruns would be avoided. Furthermore, the presence of terminology about human factors engineering, habitability, and survivability in a program’s documents prior to the Milestone B decision point was a good indicator that schedule slippages and cost overruns would be avoided.
