The Seven Quality Management (7M) Tools
Affinity diagrams:
organizes ideas into meaningful categories by recognizing
underlying similarity. It is a means of data reduction in
that it organizes a large number of qualitative inputs into a
smaller number of major dimensions, constructs, or
categories.
Tree diagrams:
breaks down or stratifies ideas in progressively greater
detail. The objective is to partition a big idea or problem
into its smaller components.

7M Tools (contd)
Process Decision Program charts (PDPC):
designed to help prepare contingency plans. The emphasis
of PDPC is the impact of problems or issues on the project.
Matrix diagrams:
constructed to analyze the correlations between two
groups of data.
Interrelationship digraph (ID):
designed as a means of organizing disparate ideas by
arranging related ideas into groups in an attempt to define
the ways in which the ideas influence one another.

7M Tool (contd)
Prioritization matrices:
used to help decision makers determine the order of
importance of the activities or goals being considered.
Activity Network diagram:
used to determine which activities are to be performed,
when they must be performed, and in what order.

Affinity Diagram
Affinity diagram is a way to organize a large
set of ideas
Very helpful for any team with a
brainstorming session, when analyzing
information
Encourages the participation of all in the
group
Similar items can be categorized and central
themes emerge
5
Affinity Exercise
Each person write out 5 post it notes quickly
with requirements you have for your next
vacation. Do not discuss with others in your
group
After everyone has 5 done put them out on
the table or flip chart
As a group organize them into clusters
Apply a heading to each cluster/group
Affinity Diagram
Tree Diagram
A systematic method to outline all the
details needed to complete a given
objective.
Partition a big idea or problem into its
smaller components.

Process Decision Program Chart
(PDPC)
Used to chart the course of events that
will take us from a start point to our final
complex goal.
Designed to help prepare contingency
plans.
The emphasis of PDPC is the impact of
the failures (problems) on project
schedules.

Matrix Diagram
Is used to show the relationship between
objectives and methods, results and causes,
tasks and people, etc.
Used to determine strength of
relationships between a grid of rows and
columns
Can identify key aspects based on
relationships

Interrelationship Digraph
Interrelationship digraph (ID): designed as a
means of evaluating the ways in which
disparate ideas influence one another. Used
to identify the critical issues and key drivers
of a problem.
Often uses input from other tools: affinity
diagram or fishbone.

Prioritization Matrix
Prioritization matrices: used to help
decision makers determine the order
of importance of the activities or
goals being considered.
17
Steps to Create Solution Prioritization Matrix:
#1: Create a list of 'want' criteria (CTQs)
#2: Weight the list of 'want' criteria (CTQs) on a scale of 1 to 10
#3: Compare the list of solutions to the weighted criteria (CTQs) and score on a scale of 1, 3, or 9
#4: Multiply the weight by the score for each criteria to get the weighted score for each criteria (CTQs)
#5: Compute and discuss the total scores for each solution
Criteria and Weights
1 2 3 4 5 6
Location / Accommodations -
Cost less Climate warm, Family travel time less - pool, food,
Potential Criteria Safety than 2.5K not hot Activities than 5 hours comfort
Solutions CTQ Weight (1-10) Total
Atlantis in the Bahamas 0
Lake George 0
Outer Banks, NC 0
Niagara Falls 0
Cruise to Caribbean 0
0
Rate each Solution to the weighted Criteria on a scale of 1, 3, or 9
1 = low, 3 = moderate, 9 = high

Summary
The Affinity Diagram is a useful brainstorming tool and will
energize your team.
The Interrelationship Digraph comes in handy when the team
needs to agree on the most likely cause(s) and effect(s)
contributors.
The Prioritization, Matrix, PDPC, Tree and Activity Network
Diagrams are effective planning tools as they help the team
build consensus on priorities, relationships and identify the
elements required for effective execution of a given plan.
Start by taking small steps with the Affinity Diagram and the
Interrelationship Diagraph. They are both fun tools to use.
