Six Sigma techniques

To combat a cycle of Blame the System mentality, a constant active search for defects in the system, as Six Sigma techniques stress, is necessary. The objective is not to change the system but to find and fix the defects or errors in the current system (How to Effectively Assess and Improve your Safety and Health Program through Safety and Health Evaluation, n.d. Six Sigma Measure Phase, Data Collection Plan and Data Collection, n.d.). 

Black belts They are experts in Six Sigma methods and tools. Tools include statistical analysis. Black belts are project leaders for Six Sigma initiatives, they also train other staff members in Six Sigma techniques. 

Hazard identification Identify hazards and consequences of exposure. Hazards are identified by analyzing the tasks grouped by function. During the identification of each task, the risk analysis assesses the potential consequences of exposure to the hazards. The classic problem solving format Who, What, Where, When, Why, and How (How much How Many ) Is used to define the root cause. This method is called the 5W2H method that is used in Six Sigma techniques to help to identify a root cause. 

Many people are familiar with work processes, including Bottom Line Innovation, TRIZ, and the various Six Sigma elements. These standardized techniques for work processes have gained a broader use throughout the chemical industry. 

Because there are so many different ways to calculate process capability, it s common to use the wrong metric. This creates an erroneous impression of how well the process runs, and creates confusion when comparing the performance of different types of variables and processes (service, manufacturing, transactional). Therefore, this technique is best applied at first with the help of a statistical or Six Sigma expert. 

While Six Sigma is a fine-tuning exercise that can be applied to any of the three, the principles of TQM, TOC, and TPS were different techniques that took companies down different paths, ft is convergent thinking that is still being rationalized today. Many companies are confused. 

Quality Function Deployment (QFD) is a technique to translate requirements — defined by customers — into specifications for a product or service. The tool is promoted as part of total quality and Six Sigma improvement efforts. QFD captures the voice of the customer and has application for supply chain processes, including physical flow, needed flexibility, extended product features, and new product introduction. QFD forces supply chain designers to consider customer needs important in design. This lowers the risk of leaving something out. 

Six Sigma is a philosophy relating to defects based on a normal distribution but has become synonymous with the development of structured approach to the improvement of organisational systems and processes, using total quality management techniques. Staff can be trained as black belt facilitators of the six sigma approach. 

Six Sigma is a set of techniques and tools developed by Motorola in 1986 widt special emphasis for setting extremely high objectives, collecting data and analyzing results to a fine degree to reduce DEFECTS in products and services. It can be conceived as a disciplined, data-th iven approach and medtodology for elimination of defects in products and services, this technique mainly uses empirical and statistiad methods and data for analysis. 

Although Six Sigma had its beginnings as a quality performance standard, some safety professionals have sensed its value and promote its adoption. An example is a paper written by Jack B. ReVelle (2004) titled Six Sigma Problem-Solving Techniques Create Safer, Healthier Worksites. It was published in the October 2004 issue of Professional Safety. This is how the author commences.

In any organization, there is a desire to improve quality, whether it is the quality of a product or the quality of processes within the company. Lack of quality costs money and puts companies out of business. Quahty is dynamic so there is always room for improvement. Top companies have a focus on quality. There are several techniques used to improve quality one common one is Six Sigma. 

Six Sigma is a process to improve performance. There are thick books on the topic and entire courses devoted to training someone on the topic so what follows is just a brief synopsis of the technique. The name derives from the Greek letter a , or sigma, which is used as an abbreviation for standard deviation. The standard deviation is the square root of the variance. If the data fits a bell-shaped normal distribution curve, 68% of the numbers will fall within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations. Six Sigma has a focus on decreasing the number of defects. A defect is anything out of specification. 

These techniques can be used throughout an organization or in smaller pieces such as a particular chemical process. Eor example Lean Six Sigma has been used to improve a selenium analysis [6] and showed the importance of improving the digestion of the sample. 

Six sigma tools and techniques enable the proper execution of the DMAIC cycle and ensure that decisions are based on hard quantitative evidence. 

Manufacturing is all too often taken for granted, but its consistent, qualityconscious, timely, and cost-effective execution is crucial to the success of any nonservice company in the industry. The leading firms of fhe indusfry have adopted Total Quality Management (TQM), Six Sigma, or other such techniques to ensure continuous improvement in consistent quality, which also typically leads to cost savings. 

Several methods are available for understanding the hazard categories in the working interface. Techniques drawn from Six Sigma, Lean Systems, and behavior-based methodology can all be...
