Critique of Six Sigma Quality Assurance

Introduction Software Quality Assurance (SQA) is designed to monitor the software engineering process to ensure the quality of software. Quality is also added to three constraints of software development such as time, range, cost. As quality is also added, it is now called 4 times constraint. There are various test standards, each with advantages and disadvantages. Research on test standards is still ongoing and is also important for software development companies. For software development companies, they will be able to satisfy the needs suited to the needs of software and help select standards that are appropriate for their company.

How to Improve the Six Sigma Quality Since its founding, many organizations have adopted Six Sigma for quality improvement. In the 1980s, Motorola measured and improved the quality of products and services. Six Sigma is focused on one million opportunities per flaw. Six Sigma is based on quality statistics, which is equivalent to 4 defects per million opportunities. This is the target performance level of the process. Six Sigma DMAIC Quality Improvement Model Robert Galvin's Six Sigma Quality Improvement Model applied in Motorola refers to a five step process solution called DMAIC. (Definition, Measurement, Analysis, Improvement, and Management) Definition: In this step, you define who the customer is, what the customer needs, and processes.

There are six Six Sigma processes: Six Sigma DMAIC and Six Sigma DMADV, each term comes from the main step of the process. Six Sigma DMAIC is a process for defining, measuring, analyzing, improving, and managing existing processes under the Six Sigma specification. Six Sigma DMADV defines, measures, analyzes, designs, and verifies new processes or products trying to achieve Six Sigma quality. All Six Sigma processes are performed by Six Sigma Green Belt or Six Sigma Black Belt and are supervised by the term created by Motorola, Six Sigma Black Belt Master

The 40 Six Sigma "Black Belt" sitting in front of me looked at me carefully, everyone weaved and weaved. I was asked to introduce design thinking to them. I do not have any color Six Sigma belt. I fully acknowledge that I do not know the difference between 6 and any other digital sigma. I decided to design design thinking with "Marshmallow Challenge" by TED conference 2006, former designer of product design company IDEO Peter Skillman. Exercise was like this. Four teams built the highest autonomous structure for 18 minutes using 20 straight spaghetti, 1 yard masking tape, 1 rope and marshmallows. You can change all the materials, but marshmallow, "best" is defined as the vertical distance between the bottom of the tower and the top of the marshmallow.
