Six Sigma is an intra-process improvement game plan which uses statistical analysis to decrease abnormalities and intensify quality (Antony, 2011). Six Sigma focuses on variation reduction, reducing cost through variance reduction, etc. Six Sigma uses more statistical tools and is used for tackling more complex problems with unknown solutions (2011, p. 187). Lighter (2011) lists seven Six Sigma metrics in all that indicate the initiative process operation advancement. One metric is the defects per unit (DPU) measure which calculates the number of revisions or repeats obtained per each unit of output. An example would be if 30 class pictures were taken, but 60 exposures were necessary to get acceptable images, the DPU would be 2, or 60 divided by 30. The first-pass yield is another metric used in the Six Sigma approach. The first pass-yield essentially is dividing the total output units by the total input units over a specific timeframe and it tells us the percentage of units made without defects. The first-pass yield indicates the ability of the process to produce conforming output that satisfied customer requirements, while at the same time providing insight into the level of rework inherent in the process (Lighter, p. 298). The rolled throughput yield (RTY) is also a Six Sigma metric that is used to assess how likely a unit can be produced through the full process without defects. Saghaei, Najafi, and Noorossana (2012) find that the RTY method can give insight into performance established on efficiency and effectiveness of the process.
The model used for improvement with Six Sigma is define, measure, analyze, improve, and control, also known as DMAIC. de Mast and Lokkerbol, J. (2012) describe the DMAIC method as a problem-solving pathway and approach to improvement. They further note that It is instrumental in the implementation of Six Sigma as a process improvement methodology (2012, p. 613). Six Sigma focuses on quality and consistency by measuring the quantity, frequency, and likelihood of defects. We as human beings have all fallen and our reasoning is flawed. However, through the sacrifice of Jesus Christ for our sins, we have been redeemed. for all have sinned and fall short of the glory of God, and all are justified freely by his grace through the redemption that came by Christ Jesus (New International Version Bible, 2011. Romans 3:23-24).
relpy 2:Six Sigma measures the success of a project. Three Six Sigma metrics that could be used to measure success is first-pass yield, defects per unit, and DPMO. The first-pass yield is a good measure of the effectiveness of a process and the elimination of waste from that process. Many other measures of productivity and efficiency fail to account for the cost of rework and in many facilities, rework can be a significant portion of the time and value-added to final production. First pass yield can also be a good measure of the success of continuous improvement activities. Very often continuous improvement initiatives are focused on the reduction of waste and inefficiency, which can be hidden from analysis if first pass yield is not measured. The formula for the first-pass yield is First pass yield = (units of products completed from process to specification with no rework) / (total units of products entering the process) (Littlefield, 2013) Defects play a central role in the Six Sigma methodology because the goal of many Six Sigma-DMAIC based projects is to improve process performance and customer satisfaction by reducing the defect rate. Defect Per Unit (DPU) is a metric that expresses how your product or process is performing, based on the number of defects. (Jordan, n.d.) The formula is DPU=total number of defects found in the sample/sample size. The DPMO is the total number of defects divided by the total number of opportunities for a defect, multiplied by 1,000,000. Defects are critical characteristics of a sampled entity that fail to meet customer expectations. Opportunities are critical characteristics of a sample that could be defective or non-defective (i.e., meet expectations) (Lighter, 2011) DPMO is one of the useful tools to know the chances for defects during the production process so we can use available resource properly and control the defects happening during the production process. DPMO used to know the number of opportunities to make defects under the production process. (Thakur, n.d.)
My son do not forget my teaching, but let your heart keep my commandments, for length of days and years of life and peace they will add to you. Let not steadfast love and faithfulness forsake you; bind them around your neck; write them on the tablet of your heart. So, you will find favor and good success in the sight of God and man. (Proverbs 3:1-4 ESV)
