A voting method to take a large list of ideas and scope them down into a more manageable range. The number of ideas is N and this is divided by 3, giving each person that number of votes. For example, if there were 33 ideas, N/3 = 11 and each person would vote for their top 11 ideas.
Doing more than one task in a single motion or function. A method of combining manual work sequences to flow smoothly or to combine machine motions. Nagara is a Japanese for "while doing something".
The process of developing consensus or agreement to an idea through informal discussion and gathering input from stakeholders.

A type of qualitative data that contains a set of possible values that has no measurable sequence to them.
A failure of a process, service or product to meet a specified customer requirement.
Refers to any materials, components, or products that do not meet specified criteria, standards, or requirements in a manufacturing or production process. NCM can arise due to various reasons such as defects in manufacturing, damage during handling, or deviations from quality standards. Identifying and managing nonconforming materials is crucial for maintaining product quality and safety. It typically involves segregating these materials to prevent their use in production, analyzing the cause of nonconformity, and taking corrective actions to rectify the issue and prevent recurrence. The handling of NCM is an integral part of quality management systems in manufacturing and production environments.
Activities that add cost but don't add value in the eyes of the customer, but cannot be currently eliminated without causing harm. Examples include inspection, packaging, recordkeeping, regulatory compliance etc.
A statistical process used to determine whether a sample or any group of data fits a standard normal distribution. Normality tests can be performed mathematically or graphically.
An arrangement of data set wherein most of the observations cluster around the central peak, with the probabilities for values further away from the mean tapering off equally in both directions.

Abbreviation for new product introduction. The overlap between the latest stage of product development and the earliest stage of volume production.
An attributes control chart used with data collected in subgroups that are the same size. Np-charts show how the process, as measured by the number of nonconforming items it produces, changes over time. Its process attributes or characteristics are always described as o/no go, yes/no or pass/fail.
