“A Lean Book That Actually Works on the Floor”
“As a leader who has sat through countless complex Lean seminars, this book is a breath of fresh air. Todd Drummond strips away the academic consultant fog and delivers a practical, no-nonsense roadmap for operational excellence. It is easy to read, easy to teach, and—most importantly—easy to sustain.”

Stop Chasing Efficiency, Remove the Bottleneck, and Let Profits Rise
This 10-page PDF explains the Theory of Constraints (TOC): find the step that limits completed work, then focus improvement there. It applies to manufacturing, office, and administrative workflows.
Inside the Guide
- Find the bottleneck: follow one real job and compare time spent working with time spent waiting.
- Choose the right improvement: distinguish local labor savings from changes that increase finished output.
- Apply the five TOC focusing steps: protect the bottleneck, align supporting work, add capacity when needed, and find the next constraint.
