About Webinar

Join our webinar to learn about the lean technique of Mistakeproofing! If you haven’t heard of Mistakeproofing, (also referred to as Poka Yoke), it is focused on the prediction, prevention and process of eliminating errors in our work execution, with the goal of reducing the potential of making mistakes and the associated waste. This supports one of the core tenets of lean – ‘Respect for People’ focusing on improving the process, not on blaming the person. People make mistakes – to err is human – but we can reduce the likelihood that a mistake will occur or alleviate the impact of a mistake that has occurred. You will hear about a framework that distinguishes 6 principles of mistakeproofing, along with examples to learn why some mistakeproofing practices are better than others. This is something that everyone can relate to, regardless of role … whether at home, at work, or both!
