The document discusses an employee motivation model called the 4-Drive Model developed by Lawrence and Nohria in 2002. The model proposes that there are four core drives that motivate employees: acquiring resources, bonding with others, comprehending or feeling challenged by their work, and defending their beliefs. The document argues that understanding and appealing to these four drives can help increase employee effort, retention, persistence, creativity, and focus, thereby improving overall motivation. It provides some examples of how organizations can impact each of the four drives through strategies like reward systems, workplace culture, job design, and building a strong reputation.
