# Scatter Diagram Template

A scatter diagram is a graph that helps you visualize the relationship between two variables. It is used to check if changes in one variable are associated with changes in the other variable. For example, a scatter diagram can be plotted to check if there is a relationship between the number of months a person has been on the job and the time it takes him or her to complete his or her duties.

# 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.

# Matrix Diagram Template

A Matrix Diagram is a table that allows sets of data to be compared to understand the relationship between them. It displays the existence and strength of the relationship between pairs of items of the data sets. The relationship is indicated by a number or symbol in each cell where each two items intersect in the matrix. Matrix diagrams can be useful in a wide range of applications from matching requirements with specifications to assigning responsibilities based on competencies.

# 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

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

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 Diagram

Many situations require the investigating whether a relationship exists between two or more variables. A line manager, for example, may want to check the relationship between the number of training hours and employee productivity, or if the number of defects is a function of the experience of the person causing it. A call center manager may be interested in studying the relationship between the number of people working on a shift and the average answer time.

# SIPOC Analysis

A SIPOC Map is high-level summary of the process. It provides a big picture view of the important elements of the process to gain deeper understanding of the context in which the process occurs. SIPOC is an acronym that stands for Suppliers, Inputs, Process, Outputs and Customers.

# Histograms and Box Plots

Histograms and box plots are graphical representations for the frequency of numeric data values. They aim to describe the data and explore the central tendency and variability before using advanced statistical analysis techniques. In this article, we will further discuss the similarities and differences between these two tools.

# Flowcharting

A flowchart is a graphical tool that illustrates the flow of a business process and the relationships between its activities. It allows to break up any process into individual activities to see how it looks like. The simplicity of flowcharts make them useful for understanding processes and finding waste and inefficiencies for further problem-solving efforts. They can be used for any process and in any industry.

# Mind Mapping

A Mind Map is a tool that is used to visually organize ideas, thoughts and information. It is a collection of words, arrows and drawings that are organized together around a single topic or problem. Ideas can be collected through brainstorming or other group activities before they are consolidated into a single map. A mind map has many applications in personal, professional and educational situations.
