Managing these processes is a key to success for any organization. A process can be defined is a set of steps designed to produce a product or service to add value to a customer. It starts with a business goal and ends with the achievement of the that goal.

Graphical Analysis


Graphical Analysis

Graphing the data can be utilized for both historical data already available and when analyzing the data resulting from live data collection activities. Of course, you need to pick the right graphical tool as there are a lot of different ways to plot your data. A number of commonly used graphical tools will be covered here. However, note that if one graph fails to reveal anything useful, try another one.

Cause and Effect Matrix Template

The Cause and Effect Matrix is used to understand the relationship between causes and effects. Whenever an output variable drifts out of specification, that is an effect. When an effect goes out of specification, you need to rank the potential causes in terms of importance, and the causes with the highest overall score should be addressed first in improvement efforts.

Relationship Mapping

Relationship Mapping

A Relationship Map is a visual display that shows the relationships between individual items. It allows to see and analyze the logical links between the different elements of any situation. A simple example of a relationship map is your network of personal and social relations. Another example is what is called the Interrelationship Digraph which is a visual display of the cause and effect relationships involved in a process or problem. Read more »»

Matrix Diagram

Matrix Diagram

A Matrix Diagram is a table that allows sets of data to be compared in order to make better decisions. It displays the existence and strength of relationship between pairs of items of two or more sets. The relationship is then indicated by a number or symbol in each cell where the two items intersect in the matrix. A matrix diagram can be used as part of other decision making tools. Cause and Effect Matrix and Quality Function Deployment are examples of tools that use the matrix diagram. Read more »»

Fishbone Diagram

Fishbone Diagram

Sometimes it is difficult to spot problems and only symptoms will be acted on leaving the real causes intact. This indicates lack of information and poor understanding of the problem and leads usually to a weak solution. A Fishbone Diagram is often used to identify and organize the potential causes of a business problem in an easy and understandable format. It is used to identify the sources of process variation which caused the problem to occur. It is called this way because of its shape that looks like a fishbone. It is also called Ishikawa Diagram and Cause and Effect Diagram. Read more »»

Scatter Plots

Scatter Plot

Many situations require the investigating whether a relationship exists between two or more variables. A Scatter Plot is a diagram showing whether two variables are correlated or related to each other. It shows patterns in the relationship that cannot be seen by just looking at the data. It is often used as a first step in analyzing and communicating the correlation between pairs of variables before conducting advanced statistical analyses. It works with both continuous and count data.

Histograms and Boxplots

A histogram is a graphical representation of a frequency distribution for numeric data. It is a bar chart that is often used as the first step to determine the probability distribution of a data set or a sample. It allows to visually and quickly assess the shape of the distribution, the central tendency, the amount of variation in the data, and the presence of gaps, outliers or unusual data points.

Pareto Analysis

Pareto Analysis

There are many situations where you are asked to decide which problems or causes of a problem should be tackled first. The Pareto Principle, which is also referred to as the 80-20 rule, states that roughly 80 percent of the problems or effects come from 20 percent of the causes. It describes a statistical phenomenon that a small number of high values contribute more to the total than a high number of low values. The focus of the Pareto Analysis is to identify the “vital few” from the “trivial many” and make it possible to attack the 80 percent of the problems to obtain the maximum benefits.

Failure Mode and Effect Analysis Template

Failure Mode and Effect Analysis (FMEA) is a risk analysis tool that can be used to identify the points at which the process may fail. It is a systematic approach that identifies potential failure modes, their causes and effects, and identify actions to reduce or correct the failures. After identifying a high risk, it is necessary to do something about it. FMEA could be applied to manufacturing and non-manufacturing processes, and can be performed at the system, assembly or part level.
