Process map (Flow chart)
A Process Map or a flowchart is a picture of the separate steps of a process in sequential order. Also called: process flowchart or process flow diagram.Elements that may be included in a Process Map are: sequence of actions, materials or services entering or leaving the process (inputs and outputs), decisions that must be made, people who become involved, time involved at each step and/or process measurements. An example of high level Process Map is:
The process described can...

CTQ (Critical to quality)
Tagucci said “If you cannot measure a customer requirement, you will not know if you`ve improve it”.Starting from this affirmation we have to think how to transform the customer's voice into a measurable indicator. CTQs are the key measurable characteristics of a product or process whose performance standards or specification limits must be met in order to satisfy the customer. Typically, a CTQ must be interpreted from a qualitative customer statement to an actionable, quantitative...Read this article...
Voice of the customer (VOC)
Voice of the Customer (VOC) captures how customers feel about their experience with a business, product and/or service.The concept of “putting the customer first” is based on the fundamental assumption that most things done to increase customer satisfaction will have a favorable downstream effect on the business.Read this article...
The purpose of graphical analysis
The use of the graphic method of presenting statistical data is done in order to reproduce in a simple, attractive and suggestive form the essential features of the processes studied in certain conditions of time and space.Starting from the well-known proverb "A picture is worth a thousand words", graphical analysis has the possibility to concentrate a large amount of information in a minimal space.From a theoretical point of view, for the same statistical data there are several possibilities...Read this article...
Regression
In statistics Regression is a statistical process that estimates relationships between variables. Regression models involve the following terms:Independent variables, x;
Dependent variables, Y.
The equation Y = f (x ) is converted to numbers and allows us to find the required level of x in the expression for a given Y.This way when the customer changes to a different Y, the new value of the variable x can be quickly identified so that the new requirements are met.Regression helps us...

Pareto
Pareto chart is a type of diagram that contains both bars and a line graph, where individual values are represented in descending order by bars, and the cumulative total is represented by the line. The purpose of Pareto chart is to highlight the most important factors from a set of data and to allow prioritization.The name is coming from Vilfredo Pareto, an Italian economist who studied the distribution of wealth in different countries. He concluded that 80% of income in Italy was received by...

Histogram
A histogram is a graphical representation of the distribution of numerical data. This can be used when working with a lot of data. The purpose of a histogram is to graphically summarize the distribution of a data set.In fact, this representation is a specialized version of the bar chart used in excel. The possible values of the selected variable are represented on the horizontal axis. Frequencies are represented on the vertical axis.Individual data are grouped into classes so that we get...Read this article...
PDCA (plan, do, check, act)
PDCA was named for the first time in the 30`s by Walter Shewhart, who discussed about this concept in his book “Statistical Method from the Viewpoint of Quality Control”.PDCA cycle have connections and is pretty the same as other problem solving methodologies, simple or more complex, like 8D, DMAIC from Six Sigma. Even recent changes to ISO 9001 process-based orientation chapter came with new concept risk-based thinking - closely linked with the PDCA.Read this article...
Statistical Process Control with Q-DAS qs-STAT
Statistical Process Control (SPC) is a quality control method that uses statistical methods. It is used to monitor and control the processes. Principal elements of SPC are control chart and process capability study.Read this article...
Measurement System Analysis with Q-DAS Solara
MSA is an experimental mathematical method that determines how much of the total variation observed is due to the measurement system itself. It helps us to determine the ways in which a measurement system needs to be improved. Measurement System Analysis (MSA) is a first step that should precede any decision, including the use of Statistical Process Control.Read this article...
QFD
QFD, the English acronym for Quality Function Deployment, is a system for designing a product or service based on customer requirements that involves all members of the manufacturing/supplier organization.The system is explained by its very name:Quality = meeting customer requirementsFunction = what needs to be doneDeployment = Who, how, when will doQFD was implemented for the first time in Japan, at the Kobe Shipyards belonging to the Mitsubishi company - between the years 1977 - 1984,...Read this article...
Visual Management
LEAN is a visual management tool of effective communication within an organization or even in everyday life, being a simple presentation methodology, useful information in visible places.Visual management is based on transmitting information by images instead of text in order that the information to be more concentrated and faster to process.Read this article...
Leadership and team motivation
The role of leaders in organizations is to set the direction, to provide resources and remove bottlenecks, monitor achievement of goals with the team, and not least to be a model.For a healthy and strong leadership, in the relationship of leader with the team must be some elements such as goals, direction, roles of each in the team, but also motivation and professional development, elements that give a team confidence and trust each other.Read this article...
QRQC
QRQC is a problem-solving methodology, based on 8D methodology, and was being developed in JapanThe methodology can be used to solve and response to quality complaints from the client, or to solve an internal problem, selected based on its importance.Read this article...

Design of experiments (DOE)
Design of experiments (DOE) is a systematic method to determine the relationship between factors affecting a process and the output of that process. In other words, it is used to find cause -and-effect relationships. This information is needed to manage process inputs in order to optimize the output.An understanding of DOE first requires knowledge of some statistical tools and experimentation concepts.
Although a DOE can be analyzed in many software programs, it is important for...

Control Plan
A Control Plan is a written summary that describes what is required to maintain an improved process at its current level.It includes human resource and training requirements, actions to be taken if measurements/indicators fall outside the specified range, and actions to ensure process owners maintain process improvement gains.The Control Plan is part of the Control phase of the DMAIC Six Sigma (Define-Measure-Analyze-Improve-Control) methodology, however, it can also be part of other similar...Read this article...
