The vast majority of literary works and theories in the field of Industrial and Manufacturing Engineering often lack practical evidence. Therefore, the main purpose of this work is to bridge the long-lost gap between Practical and Literary principles in the fields of Manufacturing and Industrial Engineering. The book is designed to be suitable for both new and experienced lean practitioners or hobbyists and may be useful in academia and collegiate level manufacturing engineering and production management curricula. This work is also written in simple terms, while covering real-world applications and introducing practical approaches to capacity and demand management. The material focuses on most commonly used, practical, and industry-based lean manufacturing techniques making it a perfect fit for entry-level or well-seasoned manufacturing practitioners. New approaches to strategic and tactical operational planning are discussed in this manuscript. Most notably, the book covers how different "Lean" tools and techniques may apply in capacity and demand planning.
