TWI - Training Within Industry

TWI is a training methodology in the use of standard procedures developed for the American industry during World War II. TWI divides the training into four steps:

Implemention steps
  1. Develop standards: SOP and JBS, in the pilot area
  2. Train in TWI – teach trainers in the use of methodology, develop a support structure, master trainers, etc.
  3. Teach standards to associates using TWI
  4. Establish a control system to make sure work proceeds according to standards
  5. Expand to other areas

Definition of a Standard

Standard is the best, safest, easiest, simplest and most reliable way to perform a job. As such, it is only known to people who do the work. Standards should contain information on external and internal customers’ requirements: quantity, quality, and time. It is important to make sure that there exists only one standard for any activity.

Standards are used for:

  1. Ensuring that best practices remain in house
  2. Training of new associates
  3. Problem solving
  4. Control over execution of work
  5. Continuous improvement
Not all operations require standards. Where activities are repetitive, standards should exist throughout. However, where the work is creative or highly skilled, standards will be more difficult to implement. Nevertheless, it will be desirable to standardize at least thinking blocks.
  • An operation must be performed in the same way each time
  • Work is not performed by experts 
  • Quality, cost and productivity are important
  • It is desirable to keep best practices in house
  • Work is creative
  • Work is constantly changing
  • Large amount of experience is required to carry out work
  • Work is only performed by highly skilled experts

TWI Workshop

The class teaches TWI methodology and implementation of standard work. Participants practice developing standards and training in their use during simulation games. Part of the training also creates initial standards in the pilot area and develops a training plan.
