This book is dedicated in memory of longtime Northern Logger Editor Eric A. Johnson.
The book describes the widely used continuous improvement theory and process and how it relates to logging. Continuous improvement, also knows as the Theory of Constraints, simplifies complicated processes and demonstrates how incremental progress is made by overcoming bottlenecks. System bottlenecks specific to logging are explored and described. Throughout, accounting is adapted to logging with straightforward calculations that show financial results for individual harvesting jobs. Productivity is related to financial well being of a logging business. Harvesting machine and system productivity tables are presented.
