Six Sigma Terminology - R to T

Random Sample

A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen. An example of a simple random sample would be the names of 25 employees being chosen out of a hat from a company of 250 employees.

Root Cause Analysis

Root Cause Analysis is a process or procedure that helps guide people to discover and understand the initiating causes of a problem, with the goal of determining missing or inadequately applied controls that will prevent recurrence.

Reliability

The ability of an apparatus, machine, or system to consistently perform its intended or required function or mission, on demand and without degradation or failure.

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.

Learn How To Use The Fishbone Analysis Tool

The fishbone diagram identifies many possible causes for an impact or problem. It may be used to structure a brainstorming session. It immediately sorts concepts into important categories.

Use of Fishbone Diagram

When figuring out possible causes for an issue.
Particularly when a team’s considering tends to fall into ruts.

Fishbone Diagram Procedure and Example

Materials needed: flipchart or whiteboard, marking pens.

Agree on an issue assertion (impact). Write it on the center proper of the flipchart or whiteboard. Draw a field around it and draw a horizontal arrow operating to it.

Six Sigma Tools - Fishbone Analysis

The fishbone (or Ishikawa) diagram is one other technique to visualize 5-why evaluation and permits you to classify your evaluation into broad classes. Half three of a sequence on the five-whys. The fishbone diagram, also called the Ishikawa diagram, is one other instrument to give you a visible illustration of your 5-why evaluation. The energy of the fish bone diagram is that it permits you to deal with particular trigger classes, which can allow you to raised focus your line of inquiry. In different phrases, this diagram is just like a surgical strike, which offers extra precision. The desk technique is just like the shotgun method, during which we consider as many potential causes as doable and not using a particular path.

Arrange the Fishbone

Firstly, on a sheet of paper, draw a protracted line with the field on the finish. The road represents the backbone of the fish. Within the field, write down the impact. On this case, it's “Software processing was delayed.”
