Optimizing Workforce Performance: Perceived Differences Of Army Officer Critical Thinking Talent Across Level Of Education, Richard B. Ayers

Dissertations

The U.S. Army’s operating environment continues to become increasingly complex and unpredictable, where U.S. technological advantage continues to erode. The complexities stem from the Army’s doctrinal assumption that the future operating environment is unknown and constantly changing (Department of the Army [DA], 2014a). Diminishing technological advantage results in more reliance on soldiers’ cognitive capability, and less on high technology weapons systems (McMaster, 2015).

A review of military literature shows extensive research on the importance of Army leaders to be talented critical thinkers (Fischer, Spiker, & Riedel, 2008, 2009; Gerras, 2008; Thomas & Gentzler, 2013). Human capital literature reveals many college …
