Key Findings: • Frontline supervisors play a critical role in implementing HR policies by developing employees and managing performance. • Coaching counts—one-on-one feedback from frontline supervisors increases the bottom-line by improving individual productivity. • Coaching alone isn’t enough. It is much more effective when combined with other management practices—for example, group incentives that enhance collaborative problem-solving and learning, and reinforce the lessons from individual coaching. • The resources and constraints of workplace technologies can affect the return on your frontline coaching and HR management strategies. Don’t overlook the level of process automation and rate of technical change on the job.
