Practical Examples

1. Turning Around Corporate Culture

   The book describes a company that struggled with persistent safety violations. By identifying the crucial behaviors contributing to the problem and then engaging leaders and peers in both supporting and modeling safe practices, the company achieved a dramatic improvement in safety records. The example demonstrates the importance of both social support and consequences.

2. Personal Health Transformation

   An overweight individual wanted to improve his health but struggled with self-discipline. By employing the six sources of influence—especially creating accountability with friends and structuring his environment for success—he managed to build sustainable habits and lose significant weight. The example highlights how combining motivation and ability at different levels leads to success.

3. Improving Education Outcomes

   A school district used vital behavior identification and peer accountability to improve student attendance rates. Teachers and counselors worked together to encourage consistent attendance through recognition and support networks, showing how social motivation drives collective results. The intervention led to a measurable increase in overall school performance.

4. Reducing Employee Turnover

   In a high-turnover environment, managers introduced structured mentoring and created clear pathways for skill development among employees. By addressing both motivation (intrinsic and extrinsic rewards) and ability (coaching and resources), turnover rates decreased significantly. This illustrates how intentional influence strategies lead to better retention.

5. Enhancing Customer Service

   A retail chain found that customer satisfaction lagged due to inconsistent employee engagement. By spotlighting key behaviors, training staff, and rewarding exceptional interactions, leaders aligned the entire team under shared standards. The sustained focus on vital behaviors resulted in improved customer reviews and loyalty.

6. Community Health Initiatives

   A local health department wanted to boost vaccination rates. They leveraged community leaders and implemented incentives, as well as removing barriers to access, effectively addressing all six sources of influence. The approach led to a spike in participation and better public health outcomes.

7. Transforming Family Dynamics

   One family changed nightly routines using crucial influence principles. They made expectations clear, encouraged children’s participation through positive reinforcement, and adjusted their environment to minimize distractions. As a result, evenings became less stressful and more productive for everyone involved.
