DMAIC overview (SIX Sigma)

  • The Define phase of the book covers process mapping and £owcharting, project charter development, problem solving tools, and the so-called 7M tools.
  • Measure covers the principles of measurement, continuous and discrete data, scales of measurement, an overview of the principles of variation, and repeatability-and-reproducibility (RR) studies for continuous and discrete data.
  • Analyze covers establishing a process base line, how to determine process improvement goals, knowledge discovery, including descriptive and exploratory data analysis and data mining tools, the basic principles of statistical process control (SPC), specialized control charts, process capability analysis, correlation and regression analysis, analysis of categorical data, and non-parametric statistical methods.
  • Improve covers project management, risk assessment, process simulation, design of experiments (DOE), robust design concepts (including Taguchi principles), and process optimization.
  • Control covers process control planning, using SPC for operational control, and PRE-control.
DFSS covers the DMADV framework for process design, statistical tolerancing, reliability and safety, using simulation software to analyze variation and risk, and performing ‘‘virtual DOE’’ using simulation software and artificial neural networks.

Lean covers the basic principles of Lean, Lean tools and techniques, and a
framework for deployment. It also discusses the considerable overlap between
Lean and Six Sigma and how to integrate the two related approaches to achieve
process excellence.

Waste of Transportation, 7 Wastes in Lean Manufacturing (SIX Sigma)

Transport is the movement of materials from one location to another, this is a waste as it adds zero value to the product. Why would your customer (or you for that matter) want to pay for an operation that adds no value? Transport adds no value to the product, you as a business are paying people to move material from one location to another, a process that only costs you money and makes nothing for you. The waste of Transport can be a very high cost to your business, you need people to operate it and equipment such as trucks or fork trucks to undertake this expensive movement of materials. Waste of transport is a consequence of excessively long, intersecting transport paths, temporary storage, load and unload, transport of pallets hither and thither. Waste of transport is also caused by too detailed process breakdown and exaggerated division of work, due to imprecisely defined intermediate warehouses and due to production in large series.  Waste of tra...

21st Century, Essay (IELTS)

The 21st century has begun. What changes do you think this new century will bring? Use examples and details in your answer. Man, through the ages, has undergone many changes from the time when he depicted a herd of mammoths on the walls of his cave to these days when he can create beautiful pictures and even make coffee by use of computer technologies without leaving his favorite chair. The 20th century made huge steps in developing computer technologies and reached many goals that made our life much easier. What should we expect in the 21st century? First of all, I think that the pace of our life will speed up: we will move faster from one place to another, from one continent to another using high speed jet airplanes. Second of all, I believe that we will be able to do many things that take much time now without leaving our house. Computers will be everywhere including out clothes. Many people will have chips and mini computers inserted in their heads to hold huge amount of ...

7 Wastes in Lean Manufacturing (SIX Sigma)

Over-Production Waste   Definition  • producing more than what is needed • producing faster than what is needed Causes • volume incentives (sales, pay, purchasing) • high capacity equipment • line imbalance; poor scheduling/shifting • poor production planning • cost accounting practices that encourage build up of inventory Over-production waste occurs when more goods are produced than can be sold, resulting in idle finished goods inventory. Over-produced goods are often hidden wastes since many think they are assets with value, when in fact most of them may be obsolete or costing the company unnecessary expenses just to keep them until they can be sold if ever. The just-in-time, pull system, and kanban rules prevent over-production wastes. Also, lean systems favor smaller equipment over large ones to avoid overproduction due to high but unnecessary capacity utilization. Processing Waste   Definition  • non-value added man processing • non-valu...
