CiCC
There are currently 31 CiCC in this directory beginning with the letter W.
W
Waiting
Delays or idle time experienced by resources, materials, or processes, often resulting in inefficiencies or waste.
Warning limit
Limiting values in a quality control chart that lie between the desired value (mean value) and the values for the action limits. If the characteristic value falls above or below this value, this usually leads to intensified monitoring of the process. (On the basis of DIN 55350-33)
Warranty prediction
Predictive analysis or modeling techniques aiming to forecast warranty-related expenses or issues in products or services.
Waste
Waste: Any activity that consumes resources and produces no added value to the product or service a customer receives. Also known as muda.
Waste / Muda
A term used in lean methodologies referring to any non-value-adding activities or practices within a process.
Water Strider or Water Spider / mizusumashi
A lean manufacturing concept describing a worker who supplies materials or components to assembly lines in a just-in-time manner.
Waterfall model
A sequential software development methodology involving linear and phased progression through defined stages or phases.
Weibull distribution
A probability distribution commonly used to model reliability or failure rates in engineering and reliability analysis.
Weighed voting
Weighed voting: A way to prioritize a list of issues, ideas or attributes by assigning points to each item based on its relative importance.
Weighted regression
A regression analysis method where different data points or variables are assigned different weights based on their importance.
When from text WHEN
Potentially a reference to extracting temporal information or timestamps from text data.
White Belt
Entry-level certification or role in Six Sigma or Lean methodologies, often representing basic knowledge and participation.
Whole plot and subplot error
A statistical term related to experimental design, denoting errors associated with experimental units and treatments.
Why Why
An iterative questioning technique used in root cause analysis to delve deeper into underlying causes or factors.
Wilcoxon Mann-Whitney test
Wilcoxon Mann-Whitney test: Used to test the null hypothesis that two populations have identical distribution functions against the alternative hypothesis that the two distribution functions differ only with respect to location (median), if at all. It does not require the assumption that the differences between the two samples are normally distributed. In many applications, it is used in place of the two-sample t-test when the normality assumption is questionable. This test can also be applied when the observations in a sample of data are ranks, that is, ordinal data rather than direct measurements.
Work breakdown structure
The work breakdown structure is the hierarchical breakdown of the project tasks into sub-tasks, down to level of the sub-tasks that are relevant for the person or the department. It comprises the description of the main tasks, sub-tasks and work packages. The work breakdown structure can be function-based (activities), object-based, or mixed (object and function).
Work environment
Environmental conditions at the workplace. This can include physical conditions such as temperature, social conditions such as working hours, psychological conditions such as working atmosphere, or environmental factors. (On the basis of ISO 9000:2015)
Work in Process (WIP)
Inventory or materials in various stages of completion within a production or manufacturing process.
Workdays
Days considered as operational or workable within a specific context, often excluding weekends or holidays.
Working measurement standard
Measuring instrument, measuring system or reference material whose dimensional accuracy can be traced back to a reference measurement standard, either directly or through an unbroken chain of calibrations. The working measurement standard is routinely used in order to calibrate or check material measures or measuring instruments (test and inspection equipment). (On the basis of DIN 1319-1).
Working sequence
Working sequence: One of three elements of standard work; refers to the sequence of operations in a single process that leads a floor worker to most efficiently produce quality goods.
Worksheet
A document or electronic file where data, calculations, or information is recorded, often used for analysis or documentation.
