Les infos clés
Learn about Lean Production, a customer-centric methodology that improves processes by eliminating waste and focusing on value-added tasks.
This course will introduce the main tenets of the Toyota Production System, which includes Just-in-Time manufacturing and Quality Control. We learn how to analyse process flow and see quantitatively the importance of establishing continuous flow, by calculating resource utilisation and cycle time to evaluate the impact of set up times, batching, defects and reworks. We introduce quality control tools in order to improve and stabilize our flow, using workplace visualization and discuss the critical concept of Kaizen, the Japanese practice of continuous improvement. You will see the impact of key concepts of Lean, including Heijunka, Kanban, Jidoka, Andon, Poka Yoke, and 5S, which help achieve increased quality and productivity.
Upon successful completion of this series, learners will earn the Technical University of Munich Lean Six Sigma Yellow Belt Certification, confirming mastery of the fundamentals of Lean Six Sigma to a Yellow Belt level, based on the American Society of Quality's Body of Knowledge for the Certified Six Sigma Yellow Belt.
- The history and background of Lean production and the complementing elements of quantity and quality control.
- How to measure production performance and how defects and waste degrade performance.
- To improve process performance through application of lean principles, including setup time reduction, batch optimization, and defect elimination.
- Elements of Lean production including Heijunka, Kanban, Jidoka, and Poka Yoke.
- 5S methodology for establishing and sustaining a productive work environment.
This course reviews basic calculations used in production management. Therefore, basic math skills are necessary.
Week 1: Introduction: Identification of Waste
Discuss the difference between craft and mass production and use the Process-Product Matrix to categorize production from job-shop to high volume production. Review the history of Lean Production, focusing on Japan's Toyota Production System as an alternative to the traditional mass production practiced by the American automobile makers after World War II. Discuss how waste impacts productivity and describe Taiichi Ohno’s famous Seven Wastes: Transportation, Inventory, Motion, Waiting, Over-Processing, Overproduction, and Defects.
Week 2: Understanding Flow: Capacity Analysis
Cover the basics of process analysis, including developing a process flow diagram and understanding how to calculate process capacity and resource utilization, as well as the important concepts of cycle time and takt time. Understand the relationship between inventory, a waste, is directly related to the flow time in a system through Little’s Law. Understand how variability in a system causes queuing, or waiting – also a waste – even if there is enough capacity on average.
Week 3: Continuous Flow: Setup Time Reduction
Calculate the impact of setups on capacity when the product variety is increased and understand how batching can improve this, but at the expense of inventory. Review the method of Single Minute Exchange of Die (SMED) and learn why reducing setups and changeovers are critical to process flow and lean manufacturing. Discuss the concept of Total Productive Maintenance and calculate the well-known metric Overall Equipment Efficiency.
Week 4: Improving Flow: Workplace Organisation and Visualization
Introduction to the concepts of Workplace Visualization and Organization and 5S (Sort, Set In Order, Shine, Standardize, Sustain) for improving and maintaining continuous flow in Lean Production.
Week 5: Maintaining Flow: Establishing Pull Systems and Scheduling
Define the key principle from the Toyota Production System, Just-In-Time (JIT) and the significance that JIT has for Lean Production in reducing waste and meeting customer demand. Review the relevant components of production planning: the customer demand forecast, the aggregate plan, the Master Production Schedule (MPS), and Material Requirements Planning (MRP) and how these affect Production Scheduling, the heart of Lean Production. Understand, with the help of reduced setup time, how Mixed-Model Scheduling achieves a match between production and customer and how Pull systems can be realized using Kanbans.
Week 6: Quality and Continuous Improvement
Calculate the impact defects have on our flow rate – the impact on the internal factory. Understand how Poka Yoke can help fool-proof our processes and learn how to structure and run a Kaizen Blitz to bring about rapid improvement opportunities for problem solving and process improvements. Consider the central role of Continuous Improvement in Lean Production by comparing the set of management principles set out by Toyota Motor Corporation in 2001, The Toyota Way 2001, and Jeffrey Liker’s perspective, The Toyota Way: 14 Management Principles.

EdX est une plateforme d'apprentissage en ligne (dite FLOT ou MOOC). Elle héberge et met gratuitement à disposition des cours en ligne de niveau universitaire à travers le monde entier. Elle mène également des recherches sur l'apprentissage en ligne et la façon dont les utilisateurs utilisent celle-ci. Elle est à but non lucratif et la plateforme utilise un logiciel open source.
EdX a été fondée par le Massachusetts Institute of Technology et par l'université Harvard en mai 2012. En 2014, environ 50 écoles, associations et organisations internationales offrent ou projettent d'offrir des cours sur EdX. En juillet 2014, elle avait plus de 2,5 millions d'utilisateurs suivant plus de 200 cours en ligne.
Les deux universités américaines qui financent la plateforme ont investi 60 millions USD dans son développement. La plateforme France Université Numérique utilise la technologie openedX, supportée par Google.
