One of lean manufacturing's most important calculations is takt time, or the rate of customer demand for a group or family of products produced by one process. This book provide quick guide for Takt Time calculation, machine Cycle Time and One-Piece Flow Cell.
Takt time is calculated as the amount of manufacturing time that is available divided by the volume of orders. In the 1930s, the German aviation industry employed Takt for the first time as a production management tool. The idea was widely used within Toyota in the 1950s, and by the late 1960s, it had been adopted by the majority of the Toyota supplier base. Every month, Toyota assesses the takt for a process, with a modifying review occurring every 10 days. Takt time is used to properly balance supply and demand. It gives a lean production system its beating heart.
In the decade since the publication of Rajan Suri’s landmark book, Quick Response Manufacturing, the innovative principles of QRM have been proven with impressive results at many companies, big and small, in a variety of industries. While the key principles of QRM remain unchanged, after a decade of teaching QRM workshops to senior executives, Suri has developed a clear, concise, and accessible method of presenting QRM strategy using four core concepts: 1. The Power of Time – the huge impact time has on your entire enterprise 2. Organization Structure – how to structure your organization to reduce lead times 3. System Dynamics – understanding how interactions between jobs and resources impact time to make better decisions on capacity, lot sizes, and similar issues 4. Enterprise-Wide Application – QRM is not just a shop floor strategy, it extends across your whole enterprise including material planning and control, supply management, office operations, and new product introduction Presenting new case studies on QRM implementation, It's About Time: The Competitive Advantage of Quick Response Manufacturing illustrates how QRM can not only reduce lead times but also improve quality, reduce operating costs, and enable companies to gain substantial market share. This practical reference explains how factories in advanced nations can use QRM strategy to compete with manufacturers in low-wage countries. In addition, it provides helpful pointers for QRM implementation, including accounting strategies, novel cost-justification approaches, and a stepwise process for implementation. Also included are downloadable resources with five appendices that provide a number of practical details to assist in the success of your QRM implementation. When you are ready to start implementing QRM, you will find that these appendices contain time-saving tips to help you work through implementation issues¿including simple calculation methods and tools to support the design of your QRM strategy.

THE C-LEVEL GUIDE TO SUCCEEDING WITH LEAN "With 30 years of accumulated experience, Art Byrne is one of the rare few people who can speak with authority about the pitfalls of fi nancial measurement systems, the importance of respect for people, the power of Lean in the marketplace, and the leverage from organizing people around value streams. When he writes 'Go to the Gemba and Run Your Kaizen,' we must take heed." -- MASAAKI IMAI, bestselling author of Kaizen and Gemba Kaizen "In this wonderful and important book, Byrne shows us that Lean management, understood and practiced correctly, consistently delivers spectacular results." -- BOB EMILIANI, author, Better Thinking, Better Results, and Professor, Connecticut State University "A compelling picture of how Lean techniques and attitudes enable CEOs and senior executives to create a culture for transforming a company and putting it on a highperformance path." -- JERRY J. JASINOWSKI, former President of the National Association of Manufacturers "Art Byrne provides real-world examples of how he exhibited the wisdom and courage to do the right thing, improving work practices at all levels of the organization to deliver the right results for all stakeholders. Which comes first, the wisdom or the courage? Read The Lean Turnaround to find out." -- JOHN SHOOK, Chairman and CEO, Lean Enterprise Institute "Lean is the closest thing to magic I have experienced in my 40 years in business. I recommend Lean and this book to everyone responsible for the performance of a business, particularly those in private equity like me, where leverage magnifies the importance of cash." -- JOHN CHILDS, founder and CEO, of J. W. Childs Associates L.P. "A must-read for any leader interested in understanding the strategic advantages from focusing on activities that add value to the customer experience." -- GARY S. KAPLAN, MD, Chairman and CEO of the Virginia Mason Health System Lean isn't just for manufacturing anymore . . . Few business leaders in the world have applied Lean strategy as successfully as Art Byrne has--and none has the ability to explain how to do it with such succinctness and clarity. Famous for turning around the wire management company Wiremold, where he rethought every aspect of operations from the customer's standpoint--and got everyone else in the company to do likewise--Byrne has successfully implemented Lean strategies in more than 30 companies in 14 different countries. In The Lean Turnaround, this legendary business leader shares everything he has learned during his remarkable career and shows how anyone can achieve similar results. His primary message is this: Lean strategy isn't just for manufacturing. In fact, Byrne is using this very approach in his present position at a private equity firm. Whatever type of company you run, Lean can be used to improve virtually every aspect of operations, from training and leading employees to accounting and payroll issues. The Lean Turnaround explains all the ins and outs of applying Lean strategy to: Eliminate waste in every value-added operation Deliver consistent value to customers Stimulate growth and add jobs Increase wealth for all your stakeholders Build a company culture of continuous improvement (kaizen) Instead of attempting to get customers to conform to your way of doing things--which is, sadly, what most managers are taught to do--you need to configure your company to be responsive to the customers. This is at the core of Byrne's method--and it always works.

Takt is a German word that means the speed or rhythm of something. Takt time is a number that helps make sure that the pace of making pacemakers matches the pace of selling them. One of the most important things to consider in lean manufacturing is takt time. This is the rate at which customers want a certain group of products to be produced by one step in the manufacturing process. Takt time is a number that tells us how much time we have to make each item that the customer wants. Takt time is the time available for manufacturing divided by the number of orders. In the 1930s, the German aviation industry started using Takt as a way to manage production. The concept was used a lot in Toyota during the 1950s, and by the late 1960s, most of the suppliers for Toyota also started using it. Every month, Toyota evaluates the speed of a process, and every 10 days they also do a check to make any necessary changes. Takt time helps make sure that supply and demand are in harmony. This is what makes a lean production system work and function well.

Mapping the Total Value Stream defines and elaborates on the concepts of value stream mapping (VSM) for both production and transactional processes. This book reshapes and extends the lessons originally put forward in a number of pioneering works including the popular ,Value Stream Management for the Lean Office. It reinforces fundamental concepts and theoretical models with real-world applications and complete examples of the value stream mapping technique. To educate VSM mappers on the specific mechanics of the technique, the text provides in-depth explanations for commonly encountered situations. The authors also provide a more complete perspective on the concept of availability. While they discuss availability of equipment in transactional processes, they extend the concept by elaborating on availability as it applies to employees. The calculation of process lead time for work queues is taken to an advanced level – not only is the calculation of this lead time explained, but the text also covers the very real possibility of having more work in the queue than available time. While previous books have focused on only production process VSM or transactional process VSM, this work meets the real needs of both manufacturers and service sector organizations by dealing with both types. It goes beyond explaining each scenario, to teach readers what techniques are commonly applicable to both, and also explains areas of difference so that mappers will be able to readily adapt to whatever unique situations present themselves.
