To construct an Affinity Diagram, an excellent set of
instruction is provided in the TQM for Excel™ product based
on the MIT TQM methodology.
The steps are:
|
Step |
Description |
Status |
|
A |
Assemble the Right Team |
|
|
B |
Phrase the Issue to be considered |
|
|
C |
Generate and Record Ideas |
|
|
D |
Enter the Ideas into Affinity for Excel™
program |
|
|
E |
Display the Completed Cards or Affinity for
Excel™ |
|
|
F |
Arrange the Cards into Related Groupings |
|
|
G |
Create the Header Cards |
|
|
H |
Draw the Finished Affinity Diagram |
|
The team must have the necessary
knowledge to uncover the various dimensions of the issue and it
helps if they are accustomed to working together. Include those with
valuable input even if they have not been involved with the subject
in the past. There should be five to six members on the team.
It works best when the issue is vaguely
stated. You want to create a feeling of "anything goes" and
responses to the issue can be positive or negative, good or bad,
subjective or quantitative, etc. Once everyone agrees on the
question, place it on top of a flip chart page or blackboard so that
it is visible to the entire team.
-
Use the traditional guidelines of brainstorming to generate
ideas:
-
No criticism of ideas
-
Generate a large number of ideas in a short period of
time
-
Encourage participation by all team members
-
Record ideas exactly as spoken
-
Have team members write responses on small cards or Post-it
notes:
-
Be as concise as possible; no more than five to seven
words per card
-
Whenever possible, the statement should have a noun and a
verb to avoid ambiguity
-
Print clearly, as large as the card will allow
-
If you are having a NetMeeting, use MS Excel to enter the ideas
individually and then send the Excels to the facilitator.
-
Generate a new Affinity Diagram for Excel workbook
-
Enter the ideas

The team should mix the cards or
Post-its and spread them out randomly.
·
if using cards, use a large table to display the
cards;
·
if using Post-its, use a flip chart or a bare wall to
display them.
·
if using the Affinity Diagram for Excel, color code
the ideas in the data worksheet or arrange them in the Diagram
worksheet.
Be sure to allow enough space in front
of the work area to enable all team members to easily see and move
the cards.
After the cards or Post-its are
arranged by either the team or assigned individuals, they should be
sorted by the entire team simultaneously and in silence.
-
Find the First Cut Affinity:
-
Find two cards that are in some way related and place then
side by side
-
Look for other cards that are related to each other or the
selected cards
-
Repeat the process until all the cards are placed in 6-10
groupings
-
Cards that do not fit a group are loners and may form their
own group
-
When using the Affinity Diagram for Excel™, you have two
choices:-
-
Color code the similar Item in the Data worksheet
-
Generate the Affinity Diagram for all Ideas and then
move them around in the Diagram worksheet.
-
Silent Process
-
It is most effective for everyone to move the cards without
talking. This has two positive results. It encourages
unconventional thinking and discourages semantic battles.
-
Gut Level Reaction
-
Encourage team members to react rather than contemplate to
what they see. Speed is more important than deliberation in
an Affinity. It should be a high energy process rather than
a contemplative exercise.
-
Handling Disagreements
-
Disagreements over card placement should be handled
undiplomatically: if you don't like where a card is, just
move it. It will eventually settle into consensus. This
speeds up the process and allows staff to disagree with the
boss by simply moving a card.
-
Emerging Thinking vs. Pigeonholing
-
It is critical for the team to allow new groupings to emerge
from the chaos of the cards. For the process to work best,
members must avoid unconsciously sorting cards into safe
known categories as this would force fit everything into
existing logic and prevent breakthrough from occurring.
The "header" card captures the
central idea that ties all the cards together. Place this card at
the top of each grouping. Frequently a header card will not exist so
you must create one. Gather each grouping together with its header
card at the top of the column; something like in a game of
solitaire.
-
Structure of Headers
-
The header card should be concise and should state in three
to five words the essence of each grouping. The meaning of
the header card should be clear to everyone reading it.
-
Constructing a Stand-Alone Header
-
A good test for the clarity of header cards is if all the
detailed cards under each header were removed, would someone
who was not a team member understand the essence and detail
of the issues raised?
-
Two Elements of a Powerful Header Card:
-
Clearly identify the common thread that ties all of the
cards together.
-
The header should reflect the spirit as well as the
individual content of the grouping.
-
Header cards is an opportunity to create new twists in old
topics. They should not sound too familiar.
-
Choose the "[2] Generate the Affinity Diagram " option
from the Affinity Diagram menu (MS Excel Tools menu).
-
If you have color-coded the Ideas, make sure you check the "Use
COLOR as HEADER identifier" in the local setting option.
-
Save the spreadsheet in your project folder.
-
Keep the team small.
-
Ideas must be clarified -- not criticized -- during
brainstorming.
-
Avoid one-word cards; also, when possible, have a noun and a
verb.
-
Write clearly and display the cards so the whole team can see
them.
-
Don't agonize over sorting. Do sort in silence.
-
Look within the grouping first for an appropriate header card.
-
When one grouping is much larger than the rest, it likely
contains sub-headers.
-
Keep the number of headers between five and ten in total.
-
Keep the process moving.
-
Have others review and modify the end product.
