Lean concepts

Heijunka Introduction Heijunka is a tool used in lean manufacturing which focuses on eliminating waste without losing productivity through a manufacturing technique that relies on leveling production. Popularized by Toyota, lean manufacturing is often seen as an alternative and more effective manufacturing process than mass production that is commonly used in America (Friddle n.d.). Whereas mass production relies on production in large batches to obtain the lowest cost per part possible, lean production instead focuses on the flow of production, adjusting flow as demand changes. One of the primary problems heijunka serves to solve: how do you produce the correct amount of product when demand is always changing? The traditional…

The lean management methodology upon which this book was based began from the lean manufacturing principles developed by Taiichi Ohno for the Toyota company in the mid-1900s. Ohno’s approach to production was anything that did not provide immediate value to the customer was considered a waste of resources and subsequently eliminated. This revolutionized Toyota’s manufacturing procedures and inspired many modern project management styles used today. Eric Ries, author of The Lean Startup, applied…

Opportunities for improvement using Lean Management and Six Sigma principles The lean management principle originally came from the Toyota manufacturing system and it refers to the concept of reducing waste and eliminating defects during the production process. In lean management, firms analyze their operations to point out wastes and areas of inefficiencies before developing solutions to minimize these wastes and promote efficiency. While lean management principles are largely applied in the…

4.1 Lean Six Sigma Definition: Lean Six Sigma (LSS) is a methodology that improve performance by systematically removing waste and reducing variation. It is a combination between Six Sigma method and the waste reduction philosophy of LEAN engineering. Mentioning about Six Sigma, it has eight kinds of waste that no company wants during their process - it doesn’t add any value to the customers: + Defects: The product isn’t in accordance with customer wishes, inaccurate, late, incomplete Staff…

This rule describes the need of good communication. When a request comes from the customer for a part or product or service, there will be direct communication between the customer and every stakeholder involved in the process. The communication is done through the Kanban. The Kanban is a card with the requirements or request which is passed through every stakeholder to avoid the confusion. From this rule we can interpret that the Heijunka and Just in Time strategies are used to smooth the…

Fig. 1.1 Time line of lean six sigma 1.2 Literature Review: A lot of existing literature review articles are accessible on the standalone ways of lean methodology and Six Sigma methodology, however accessibility in the coordinated structure is in rare supply. Still a few endeavors have been made by the researchers in the past to arrange and recreate the current situation of LSS. Assarlind et al.[8]studied about the literature analysis of multi faceted view on LSS application. . They also…

Over the seven week course of Quality and Lean for Healthcare, the lesson explicates the understanding of Lean and six sigma yellow belt. Are project was to develop a team that was assign to a project manager in a new area within our hospital/organization. The tasked is to increase quality and lower cost in the process of applying Value Stream and Kaizen mapping. Within our discussion, we observed the understanding of the 8 waste, Lean thinking, Toyota Methodology and how to improve workflow.…

They were well established on the basis of Intermediate Maintenance Activities (IMA’s) and organizational activities. To satisfy the increase in demand for aircrafts the Goldratt Institute formulated a new organizational style, the Velocity approach which is a combination of speed and direction applied to a business model. It is based on the concepts of Theory of Constraints (TOC) – the system architecture, Strategic Design Activate Improve Sustain (SDAIC) – the deployment framework and Theory…

Research Question: How do Lean Operations and Supply Chain differ from traditional approaches? Describe the main characteristics of each approach and their strengths and weaknesses then discuss the main issues involved in managing the transition from traditional to lean operations. Operations & Supply Chain- Lean Approach Characteristics The lean approach to operations and supply chain management has been the accepted mode of functioning in many industries and services some many years now and…

After reading the article International transference of lean production systems by Reynold Peter James we have Known that the Lean production process is more than three decades old and is generally practiced for reduction of waste management and quality management. Toyota started using lean production process in 1950s to Toyota Production System was established on ideas intended to expand stream, dispose of waste of all types, and it acquired an incredible change organization by getting…
