TWI - Job Relations
Problems come in two basic forms - those dealing with products and processes, and those dealing with human behavior and relationships. JR emphasizes that people must be treated as individuals. Supervisors are given foundations for developing and maintaining good relations to prevent problems from arising. Principles include providing constructive feedback, giving credit when due, telling people in advance about changes that will affect them, making the best use of each person's ability, and earning the employee's loyalty and cooperation. When problems do arise, it teaches supervisors how to get the facts, weigh them, make the decision, take action, and check results. [PDF]
The inability to maintain standard work is a principal reason why many Continuous Improvement activities fail. Training Within Industry (TWI) is a proven, systematic method for standardizing the way supervisors, team leaders and others drive productivity and achieve consistent results. The program creates an environment in which jobs are performed the same way, by all team members, and where problem solving is done at the operator level.
TWI - Job Instruction for Standardized Work
The objective of Job Instruction is to help supervisors develop a well-trained workforce resulting in less scrap and rework, fewer accidents, and less tool and equipment damage. Supervisors are taught how to effectively break down a job for instruction. The method emphasizes preparing the operator to learn, giving a proper demonstration, identifying the key points in the job, observing the operator perform trial runs, and tapering off coaching while continuing to follow-up.

TWI - Job Methods Improvement
The aim of the Job Methods Training program is to help produce greater quantities of quality products in less time by making the best use of the people, machines, and materials now available. Supervisors are taught how to break down jobs into their constituent operations. They question details and develop new methods by eliminating, combining, and rearranging these details.
