TWI Institute

The Training Within Industry (TWI) methods help supervisors to support and instruct people and to improve daily work methods.

By years of experience in process optimization and the introduction of continuous improvement processes, we see many organizations struggle to maintain previously reached results. Again and again revitalizations are necessary to maintain the process. It often seems that continuous improvement stands far from daily practice as well. By supporting the supervisor in his or her daily work, the organization will become able to exploit creativity and knowledge of workers and remain successful.

The primary goal of the TWI Institute is integrating the TWI methods in organizations, in such a way that they become able to permanently use knowledge and creativity of all workers to be successful.

The TWI Institute will pursue its goal by: sharing knowledge of successful implementations; organizing a common platform for sharing knowledge; and by training and guiding organizations in the use of the TWI methods.

We are official partner of the global TWI Institute network. This is the global network of accredited, experienced and motivated TWI certified trainers and Lean specialists who implement the TWI methods in your organization according to the original standard.
