Training Within Industry (TWI) was developed over 60 years ago by the U.S. Department of War and was instrumental in boosting productivity within the manufacturing sector and allowing the Allies to be victorious. The TWI program is composed of a set of standardized courses to develop the fundamental skills of front line supervisors, team leaders and truly any leader of people. Because the role of small teams in daily management and continuous improvement is essential for success, the skills TWI teaches are essential for any organization seriously pursuing operational excellence.

TWI is built around three primary "J" courses:

• Job Instruction (JI)
• Job Relations (JR)
• Job Methods (JM)

The Problem Solving (PS) and Job Safety (JS) are available to supplement the 3 core J courses. These are delivered on-the-job in five 2-hour sessions. Daily training sessions involve discussion and practice using real-life examples and situations. This is followed by immediate practice and coaching ensures that the information is retained. Class sizes are kept small to maximize interaction and learning.

The TWI program follows a proven 4-step process that is simple and practical to learn:

1. Preparation
2. Presentation
3. Application
4. Testing

Because supervisors, team leaders and front line managers play such a large role in success of an lean management system, business who invest in TWI see an immediate and lasting return on investment. The Job Instruction, Job Methods and Job Relations programs result in significant improvements in safety, quality, on-time delivery and productivity. Investing in human development via TWI training also increases job enrichment and job satisfaction, improving morale and employee retention.
