Great supervisors are more than technical experts - they are leaders, coaches, trainers, and problem-solvers. The Training Within Industry (TWI) series helps frontline leaders build the practical skills they need to confidently manage people, teach work effectively, and improve everyday processes. Often referred to as the "Roots of Lean," TWI uses a hands-on, learn-by-doing approach that gives participants proven tools they can apply immediately in the workplace. Through the TWI series, participants learn how to create greater stability, productivity, and engagement across their teams. Job Instruction (JI) focuses on building consistent and reliable processes by teaching leaders how to train employees using clear, standardized instruction. Job Methods (JM) helps leaders examine the way work is done, identify and eliminate waste, and make better use of existing resources. Job Relations (JR) strengthens communication, trust, and problem-solving so leaders can create a more positive and proactive work environment. This 3-part series is ideal for frontline supervisors, team leads, emerging leaders, and anyone responsible for directing or supporting the work of others.
