Six Sigma Terminology - O to Q

Operational Cost Target

This value represents the maximum expenditure for material, labor, outsourcing, overhead, and all other costs associated with that project. This figure can then be divided between the various operations comprising the manufacturing process to control costs at each step.

Operational Cost

Sometimes referred to as Revenue or Running Costs, these are the costs resulting from day-to-day running of an operation, e.g. staff costs, hardware maintenance, and electricity. 

Operations Process

Known for leveraging economies of scale and narrowly defined tasks, it is one of a family of four work processes characterized as an on-going endeavor undertaken to create a repetitive product or result which is performed by people, planned, executed and controlled. (Artisan Process, Project Process, Operations Process, Automated Process)

Six Sigma Terminology - K to N

Kaizen

Kaizen a Japanese term that means continuous improvement, taken from the words ‘Kai‘ that means continuous and ‘zen‘ that means improvement. Some translate ‘kai‘ to mean change and ‘zen‘ to mean good, or for the better.

Six Sigma Terminology - G to J

Gantt Chart

A Gantt chart is a type of bar chart, devised by Henry Gantt in the 1910s, that explains a project schedule. Gantt charts illustrate the start and finish dates of the terminal elements and summary elements of a project

Globalization

Social, economical, environmental and technological perspectives to the many cultures that exist in the world.

Green Belt

An employee of an organization who has been trained on the improvement methodology of Six Sigma and will lead a process improvement or quality improvement team as *part* of their full-time job. Their degree of knowledge and skills associated with Six Sigma is less than that of a Black Belt or Master Black Belt. Extensive product knowledge in their company is a must in their task of process improvement.

Hawthorn Effect

Improved process data that results from process operators who know their process performance is being measured and exercise more care in the execution of the process than would normally be done.

Six Sigma Terminology - D to F

Defining terminology and solving doubts on them is a vital part you do as a six sigma expert. Terminologies are descriptive in nature and should be understood before moving ahead in studies.

Data

Data are factual information used as a basis for reasoning, discussion, or calculation; often this term refers to quantitative information. It is plural in form. The singular is “datum.”

Defect

Any undesired result is a defect.

A failure to meet one of the acceptance criteria of your customers. A defective unit may have one or more defects. ‘A defect is an inability to conform to requirements’ (Crosby, ‘Quality Is Free’), whether or not those requirements have been articulated or specified.

Defective

The word defective describes an entire unit that fails to meet acceptance criteria, regardless of the number of defects within the unit. A unit may be defective because of one or more defects.

Six Sigma Terminology - 03 to 08

There are many terminologies used within six sigma. With this brief description of six sigma terms, you will be able to differentiate between the terminologies. While there are so many to list, here are details on few of them from 03 to 08

3P

The three Ps stand for People, Product, and Process. When implementing TQM, all three parameters should be improved.

  1. People - the satisfaction of both internal and external customers.
  2. Product - conforming to the requirements specified.
  3. Process - continuous improvement of all the operations and activities is at the heart of TQM.

5C

The 5C is a very similar technique to the 5S that is used to stabilize and improve the best and safest work environment, to support a sustainable cost, quality, and delivery.

Six Sigma Terminology - A to C

Before starting six sigma journey, you should take the time to review terms of six sigma for the better understanding of its tools and techniques.

Accountability

Conditional personal or professional liability “after” the fact, determined by action or responsibility. Accountability to action assumes the willingness to be held accountable for sufficient expertise and capability. (see responsibility)

Accuracy

  1. Accuracy refers to a clustering of data about an obvious target. It is the difference between a physical quantity’s average measurements and that of a known standard, accepted ‘truth,’ vs. ‘benchmark.’ Envision a target with many arrows circling the bullseye. However, none of them are near each other.

  2. Precision refers to the tightness of the cluster of data. Envision a target with a cluster of arrows all touching one another but located slightly up and to the right of the bullseye.

Six Sigma - Terminology

Six Sigma is a strategy that teaches employers how to manage their organizations. The approach was originally adopted and developed by Motorola during the 1980’s and is now used by many organizations worldwide. Often, Six Sigma terminology can be tough for people who are newly introduced to the concept to comprehend.We have six sigma terms available in this article for the benefits of readers of ProcessExam.com. These Six Sigma terminologies are intended for the additional support while reading six sigma tutorials and blogs.

Kaizen vs Six Sigma: Daily Habit or Data Project?

Walk through almost any plant or office improvement programme and you will hear Kaizen and Six Sigma used as if they were two words for the same thing. They are not. Kaizen is a habit the whole workforce keeps, in which small changes are made continuously by the people doing the work. Six Sigma is a method a trained team applies, in which data has to prove that the cause of a defect was found before anybody claims a fix.

Both end with a better process, so the muddle is forgivable. What it costs is time. Teams charter a four-month statistical project to solve something an operator could have fixed on Tuesday, or run a week of workshops at a defect whose cause nobody has measured and watch it return by the next quarter. This article sets the two side by side on origin, practice, evidence, cadence and scope, shows where a kaizen event genuinely belongs inside a DMAIC project, and ends with the belt exams that test both.

Where did Kaizen and Six Sigma come from, and why does the origin still show?

The two approaches were born in different decades, in different industries, to solve problems their founders described in different language. That history is not trivia. It explains why one of them needs nobody's permission and the other arrives with a charter.

How to Use a Fishbone Diagram: Steps, 6M and a Worked Example

A warehouse manager reads the weekly report and sees that too many outbound orders left the dock after the promised time. Everyone has a theory: the drivers, the pickers, the software, the weather. A fishbone diagram stops the theories turning into an argument, because it makes the team write every theory on one page, sort it by category, and then go and test the likely ones. Here is how to run one properly, from the blank board to the follow-up.

Team mapping causes of a problem on a whiteboard fishbone diagram

The diagram goes by three names: fishbone, Ishikawa and cause-and-effect diagram. All three are the same picture, a spine that ends in the problem with branches of possible causes leading into it. Kaoru Ishikawa, a Japanese quality-control specialist, popularised it in the 1960s, and the Wikipedia entry on the Ishikawa diagram gives the history. Below you will find the steps, the two category sets people use, one worked example you can copy, how to pair it with 5 Whys and a Pareto chart, and the ways teams misuse it.

Is a fishbone diagram a Six Sigma tool, and what is it for?

Yes, it is one of the standard quality tools used in Six Sigma projects, though it is older than Six Sigma and is used in healthcare, software, logistics and manufacturing alike. Its job is narrow and useful: it organises a brainstorm about why a problem happens, so that a group does not fixate on the first cause somebody names.

4 Essential Traits of Six Sigma Experts

Better organizational efficiency is a common objective throughout most industries. What enterprise doesn’t stand to learn from decreasing administrative overhead, much less consumption of assets, and fewer procedural defects? This starvation has led to the rise of the Six Sigma model of data-driven enhancements to infrastructure and methodologies of enterprise practices. Consultants in this area are Black Belts - but usually, have distinctive and various ability units to fulfill numerous objectives. Keep in mind the next traits when you’re available in the market for a Six Sigma course of evaluator:

Business Comprehension, Interpersonal Skills, Project Management Skill, Six Sigma, Six Sigma Jobs, Six Sigma Organization, Six Sigma Quality, Technical Skill

1. Business Comprehension

Six Sigma Black Belts should perceive the procedures, imperatives, and objectives of their business. Tasks based mostly on enhancement initiatives should be applied by those that know the place inefficiencies lie. Earlier trade expertise is useful right here, offering Black Belts with perception into the place enhancements may be made to extend an enterprise’s aggressive benefit.
