A two-year effort to include Human Systems Integration (HSI) in the design of a new console culminated in a final summative evaluation. The HSI team conducted the assessment on the new console developed for the CVN 77 Aircraft Carrier-Tactical Support Center. The evaluation compared the Engineering Development Model (EDM) prototype against the baseline Tactical Advanced Computer Four (TAC-4) console it was designed to replace. Overall, the results demonstrated a performance improvement with statistically significant tasks having faster average completion times on the EDM. There was also overwhelming subjective data in favor of the EDM, with 100% of participants preferring it over the TAC-4. There were no "show-stopper" issues uncovered; however, there was a potential safety concern that was resolved prior to production. Recommendations were also provided for console upgrades as part of a planned technology refresh.
