The objective of this research project was to describe the current state of waste streams, identify flow patterns, recognize improvement opportunities, and recommend alternatives for waste handling throughout the window manufacturing process at Company XYZ. Due to the improper handling of the waste generated at different stages of the manufacturing process, the company incurred in significant operating costs. This project proposes improvement measures through the adoption of lean manufacturing tools to identify process deficiency indicators; striving to standardize the waste management process, achieve greater efficiency and cost reduction opportunities that enhance the company's bottom line. This was done by exploring applicable lean methodologies. Value stream mapping was utilized to identify the flow of byproduct waste throughout the manufacturing layout, data collection charts were used to quantify the amount and proportion of waste generated throughout the manufacturing process, and 5S methodologies coupled with visual management techniques were applied in order to contribute on the categorization of waste and ultimate uncover treatment alternatives. Most significantly, this project identifies a direct correlation between proper waste handling procedures and cost reduction opportunities, ultimately having a positive impact on the company's bottom line.
Lean production is the gold standard in production systems, but has proven famously difficult to implement in North America. Mass production relies on large inventories, uses "push" processes and struggles with long lead times. Moving towards a system that eliminates muda ("waste") caused by overproduction, while challenging, proves necessary for improved efficiency. Often overlooked, value stream mapping is the essential planning stage for any Lean transformation. In Mike Rother and John Shook's essential guide, you follow the value stream mapping undertaken for Acme Stamping, for its current and future state. Fully illustrated and well-organized, Learning to See is a must-see for the value stream manager.

The Lexicon covers such key lean terms as andon, jidoka, kaizen, lean consumption, lean logistics, pull, plan-for- every-part, standardized work, takt time, value-stream mapping, and many more. The new terms are: • Basic Stability • Coaching • Gemba Walk • Huddle • Kamishibai Board • Kata • Leader Standard Work • Lean Management • Lean Management Accounting • Lean Startup • Problem Solving • Service Level Agreement • Training Within Industry (TWI) • Value-stream Improvement Unlike most other business glossaries in print or online, the Lexicon, introduced in January 2003, is focused exclusively on lean thinking and practice. Like the past four, the fifth edition of the Lean Lexicon incorporates terms and improvement ideas from our customers. We continue to welcome suggestions from the growing lean community in its traditional industries and beyond.
The fact that a process produces garbage is a testament to design inefficiency, and this book explains how to use the nature of that garbage to pinpoint and eliminate those inefficiencies. Lean Waste Stream: Reducing Material Use and Garbage Using Lean Principles supplies an unprecedented look at how to address business waste in a manner that will
Lean Thinking was launched in the fall of 1996, just in time for the recession of 1997. It told the story of how American, European, and Japanese firms applied a simple set of principles called 'lean thinking' to survive the recession of 1991 and grow steadily in sales and profits through 1996. Even though the recession of 1997 never happened, companies were starving for information on how to make themselves leaner and more efficient. Now we are dealing with the recession of 2001 and the financial meltdown of 2002. So what happened to the exemplar firms profiled in Lean Thinking? In the new fully revised edition of this bestselling book those pioneering lean thinkers are brought up to date. Authors James Womack and Daniel Jones offer new guidelines for lean thinking firms and bring their groundbreaking practices to a brand new generation of companies that are looking to stay one step ahead of the competition.
Lean Process Creation teaches the specific frames—the 6CON model—to look through to properly design any new process while optimizing the value-creating resources. The framing is applicable to create any process that involves people, technology, or equipment—whether the application is in manufacturing, healthcare, services, retail, or other industries. If you have a process, this approach will help. The result is 30% to 50% improvement in first-time quality, customer lead time, capital efficiency, labor productivity, and floorspace that could add up to millions of dollars saved per year. More important, it will increase both employee and customer satisfaction. The book details a case study from a manufacturing standpoint, starting with a tangible example to reinforce the 6CON model. This is the first book written from this viewpoint—connecting a realistic transformation with the detailed technical challenges, as well as the engagement of the stakeholders, each with their own bias. Key points and must-do actions are sprinkled throughout the case study to reinforce learning from the specific to the general. In this study, an empowered working team is charged with developing a new production line for a critical new product. As the story unfolds, they create an improved process that saves $5.6 million (10x payback on upfront resource investment) over the short life cycle of the product, as well as other measurable benefits in quality, ergonomics, and delivery. To an even greater benefit, they establish a new way of working that can be applied to all future process creation activities. Some organizations have tried their version of Lean process design following a formula or cookie-cutter approach. But true Lean process design goes well beyond forcing concepts and slogans into every situation. It is purposeful, scientific, and adaptable because every situation starts with a unique current state. In addition, Lean process design must include both the technical and social aspects, as they are essential to sustaining and improving any system. Observing the recurring problem of reworking processes that were newly launched brought the authors to the conclusion that a practical book focused on introducing the critical frames of Lean process creation was needed. This book enables readers to consider the details within each frame that must be addressed to create a Lean process. No slogans, no absolutes. Real thinking is required. This type of thinking is best learned from an example, so the authors provide this case study to demonstrate the thinking that should be applied to any process. High volume or low, simple or complex mix, manufacturing or service/transactional—the framing and thinking works. Along with the thinking, readers are enabled to derive their own future states. This is demonstrated in the story that surrounds the case study.
Written by one of the world’s most respected consultants on Lean, this work presents a methodology for value stream mapping that is appropriate for any organization, whether it be service or product oriented. Over the past 25 years, Locher has proven just how powerful this process is, having employed it in healthcare, transportation, distribution, education, financial services, and manufacturing environments. Illustrating his methodology through the example of the imaginary DevelopTek company, he explains how to: Identify development waste Assess an organization’s current state and develop a Current State Map Apply Lean principles to create a Future State Map
The standard belief in books about Lean initiatives and value stream mapping (VSM) is that VSM works well on transactional processes (which are primarily linear processes where handoffs are well defined and the outcome is known) and it is useful for repetitive projects or products. This book counters these statements by clearly demonstrating how a VSM exercise can be successfully performed in complex, multifunctional environments involving nonrepetitive work, such as aircraft new product development, custom engineering, software development and project management. The methodology described in this book is the result of more than ten years of refinement and is based on practice while working with multidisciplinary teams and helping them achieve their goals. This is a novel approach to capturing the information flow in a VSM by recognizing it as the place where most of the issues are generated, especially for the previously mentioned environments and the fact that classical mapping methodologies (including classical VSM) do not capture it well. The VSM methodology that the author developed goes to the essence of a VSM (activities flow, information flow, timeline), uses conventional VSM icons and some custom information flow icons and helps the following: Quantifying waste (VSM literature gap) Making disconnects visible (VSM literature gap) Making behavioral and cultural patterns visible (VSM literature gap) If the steps are followed thoroughly, then lead time reductions ranging from 60% to 88% are achieved, along with increased availability of resources, more output with the same resources, projects delivered on time and, most importantly, colleagues embracing the Lean mindset, which greatly contributes to maintaining the gains. Essentially, this book helps readers perform a VSM in environments where multiple stakeholders interact with each other to deliver a product or a service with unclear aspects, such as what the product/service is, how all involved can contribute to the product or service transformation and how the interactions between them occur. For example, the products/services targeted in this book include test results, analysis results, a custom design, a process, a methodology, an engineering change, integrated enterprise software and engineering drawings. Concurrently, this book helps readers map behavioral patterns, such as micromanagement, and company culture aspects, such as excessive governance and "decisions by committee."
