SPC Handbook for the Treated Wood Industries

This handbook is intended to outline a strategy for wood treatment manufacturers to apply statistical process control (SPC) and other continuous improvement techniques to reduce variation in the process of treating wood. The importance of reducing variation for the wood treatment industries is fundamental to its long-term business success and improvement of the necessary treating targets. Less variation in the wood treatment process results in lower chemical operational treating targets and reduced costs. Reducing variation is the foundation for all continuous improvement philosophies, e.g., Total Quality Management, Six-Sigma Quality, Toyota Production System, Lean Six-Six Sigma, etc. The wood treatment industry is aware of process variation and it establishes minimum chemical-additive targets based on estimates of process variation across the industry. An imperative next phase for this industry is to focus on variation reduction as a competitive business strategy. SPC methods are fundamental to reducing variation. The control chart is the core tool of SPC and is the first step in quantifying variation and defining the current state of control. The control chart is also a vital tool for ensuring that operational treatment targets can be maintained and also determines if variation is reduced
