PRACTITIONER REVIEWS
What readers say
Feedback from people applying continuous improvement and standardized work in real organisations.
“I think this is an excellent guide to creating standard work using the TWI approach. The author provides 41 tips to consider when writing up the standard work and, in true TWI fashion, the reasoning behind them. The book takes you step by step through writing and improving standard work, then gives a plan for implementation and instructions for running your own TWI training course. I will be referring to it often as I start to install standard work in my department.”
“Standardized Work with TWI has seemed to me a book of great interest. I recommend reading it to all professionals dedicated to the development of continuous improvement in companies.”
FROM THE PREFACE
Why standardized work still matters
The strength of any company depends on how well it uses the potential of its people. Employees have a direct impact on quality, service and process efficiency—and human error can also contribute to defects, failures, shortages and downtime.
Automation does not remove that risk. It moves it, because people still operate, set up and change over automated workstations. Preventing errors therefore requires more than buying mistake-proof equipment. It also requires the right culture, competency management and daily habits.
Standardization is not limited to writing instructions. It builds awareness through effective instruction and creates a baseline for Kaizen. TWI provides a practical method for managing and developing capability at every level of the organisation.
