In this episode of the WLEI podcast, LEI speaks with prolific author and business leader Art Byrne.  During the discussion, Art shares his decades-long journey leading lean transformation, from running kaizen events with the first wave of ex-Toyota consultants in the US to leading manufacturer Wiremold to record profitability. For a decade, Art wrote 100 "Ask Art" columns, answering the lean community's most pressing questions. He has compiled the best of those into a new book, The Lean Turnaround Answer Book: 40 Years of Lean Observation.  Our conversation covered:  The transformative impact of implementing the Toyota Production System to improve efficiency, quality, and customer service. The critical role of leadership and involving top executives in driving successful lean transformations through setting stretch goals and fostering a culture of continuous improvement. The challenges of traditional accounting methods in a lean environment and the need to transition to lean accounting practices. The strategic advantages of reducing setup times and lead times in manufacturing, allowing companies to gain a competitive advantage. Practical insights from the author's experience writing a book to provide answers to common questions about implementing lean principles across various industries.
