The Six Sigma framework and Lean are two distinct methodologies that are often used together to improve the speed and agility of businesses and organizations.
In the context of Six Sigma, Green Belt professionals are individuals who have been trained to work on smaller or mid-sized process improvement projects within an organization. Green Belts are an integral part of the Six Sigma team and assist in implementing improvement initiatives.
In the Kano Model, the Performance feature refers to the basic and expected attributes of a product or service. These are the features that customers assume will be present and functioning properly. Meeting the Performance feature means that the product or service delivers what is expected and satisfies the customer's minimum requirements.
SMED (Single-Minute Exchange of Dies) is a collection of techniques aimed at drastically reducing the time required to execute a changeover. Shigeo Shingo, a Japanese industrial engineer, pioneered SMED, reducing changeover times by a factor of 20 across a wide spectrum of manufacturing enterprises.
Data collecting is important for obtaining information about a company's intended client base. Using surveys and questionnaires, business professionals may capture the voice of their consumers. This data includes their beliefs, interests, demographics, and purchase behaviors. The goal of employing surveys and questionnaires is to acquire current information regarding client needs.
A lower control limit (LCL) is a 3x sigma departure from the mean value of a variable.
Analysis of Variance (ANOVA) is a statistical test that compares the means of three or more samples. In the above example, each of the eight vehicle tires will be tested, and the average projected mileage will be reported. If at least two of the tires have substantially differing mileages, the ANOVA analysis confirms.
Both the mean and median are measures of central tendency that help convey where the data is centered in a dataset.
New Product Development (NPD) is typically a cross-functional business process that involves various departments and functions within an organization working together to bring a new product to the market. The process requires collaboration and coordination between different teams to ensure the successful design, development, and launch of the product.
Both the mean and median are important because they give us a sense of where the center of the data lies. However, they can differ significantly when the data distribution is not symmetrical. For example, in a positively skewed distribution (tail to the right), the mean will be pulled in the direction of the long tail, whereas the median will remain closer to the center of the data.
The term "3 Sigma standard" does not imply a defect level of 6.6%.
Defects and rework are examples of Internal Failure costs in the context of cost of quality. Internal Failure costs are incurred when defects or problems with a product or service are discovered before they reach the customer. These costs are associated with identifying and addressing issues during the production or service delivery process. Examples of Internal Failure costs include:
The Kanban technique is utilized in lean. It's a pull approach that reduces labor and inventory waste. Kanban is a Japanese term that meaning "signal card."
Six Sigma is a powerful methodology and philosophy that aims to improve business processes, enhance product quality, and ultimately lead to higher customer satisfaction and increased profits for organizations.
A SIPOC is a high-end management tool that divides variables into five categories. C-customers; S-suppliers; I-inputs; P-process; O-output
A percentage is usually used to represent the Coefficient of variation, which reflects the relative variation in a data set. A dataset's standard deviation is divided by its mean to display variance compared to the dataset's mean. This statistic may be used to compare the variance of two data sets, such as the dimensions of pencils generated by two machines.
