Training Within Industry (TWI)

Training Within Industry (TWI) consists of standardized programs that teach the essential skills needed by all people responsible for the work of others, regardless of their industry:

  • Job Relations Training (JR) teaches supervisors how to build positive employee relations, increase cooperation and motivation, and effectively resolve conflicts.
  • Job Instruction Training (JI) teaches supervisors how to quickly train employees to do the job correctly, safely, and conscientiously resulting in less scrap and rework, fewer accidents, and less tool and equipment damage.
  • Job Methods Training (JM) teaches supervisors how to produce greater quantities of quality products in less time by making the best use of the manpower, machines, and materials now available.
  • Job Safety Training (JS) teaches how to separate and clear: to prevent accidents from happening and not to resolve the aftermath. The key line of JS is, “ACCIDENTS ARE CAUSED, BREAK THE CHAIN (of causes leading to injury).”

Each of the TWI programs is structured with its own “4-Step Method.” The participants each bring in current day problems for analysis and solution using a TWI 4-Step Method and a “learn by doing” philosophy.
