Using Affinity Diagrams to Build Collaborative
Solutions
Most of us have used affinity diagrams on many
occasions to organize brainstormed ideas into natural
groupings. They also are useful for reducing the
number of brainstormed ideas into summarized headings
that can be included in minutes or presentations,
providing an overall picture of your team’s
thoughts.
A less common, but equally effective use of the
affinity diagram is to build collaborative decisions
from the summarized headings. Quite often, the
process of creating the affinity diagram will
highlight unexpected relationships among team
members’ ideas. This ensures that proposed
decisions incorporate the diverse input of all team
members, thereby making it easier to reach a
consensus.
Steps
- Ask team members to brainstorm all
considerations that should be taken into account
when formulating the decision. These considerations
may include components that should be included in
the decision, as well as those that should be
excluded from the decision.
- Each idea should be recorded on a
Post-It™ note in bold, large print that can
be read from a distance of two to four feet. Each
Post-It note also should be labeled
“include” or “exclude.”
Team members should write enough on the notes to
convey their ideas completely without explanation
to the other team members.
- Stick the notes to a wall, whiteboard, or flip
chart in random order.
- Ask team members to read the
“include” ideas silently and sort them
into five to 10 groups by moving similar Post-It
notes into adjacent positions. All team members
work simultaneously, moving the notes into the
group where they fit best. No discussion
occurs.
- Set a maximum time for reading and sorting.
Sorting can stop earlier if team members feel
sufficiently comfortable with the groups.
- Create a summary or header card for each group
by quickly selecting a word or phrase that captures
the central theme of each group. Then refine the
category header as necessary to capture the essence
of all the ideas in the group. Divide large groups
into subgroups as needed and create appropriate
subheaders.
- Repeat the process for the
“exclude” ideas.
- Draw the final affinity diagram connecting all
finalized header cards with their groupings.
- Draft a decision statement that incorporates
all the “include” headers and
subheaders. Don’t worry about making complete
sentences; just hang all the headers together in a
sensible order. Then, expand the draft by
incorporating the “exclude” headers and
subheaders.
- Ask team members to show “thumbs up or
thumbs down” whether the draft decision
statement reflects their diverse ideas. If a team
member is not ready to accept the draft, ask
him/her to go back to the headers and subheaders
and show what is missing or has been
misrepresented. Make adjustments to the draft as
needed to make sure all the brainstormed
considerations were incorporated
appropriately.
- Refine the draft into complete sentences. At
this point, some of the original ideas may be added
to clarify the headers. Avoid wordsmithing,
however; it adds no value and wastes time.
- Check for consensus by showing “thumbs up
or thumbs down” again. Remind team members
that consensus is not about perfection; it’s
about moving in the right direction.
Facilitation Tips
- You may want to require that each note contain
a noun and a verb. Under any circumstances, your
team should agree on the note-writing guidelines
before you begin.
- Sort in silence to focus on the meaning behind
and connections among all ideas, instead of the
emotions and “history” that often arise
in discussions.
- As an idea is moved back and forth, try to see
the logical connection that the other person is
making. If the movement continues beyond a
reasonable point, agree to create a duplicate
Post-It note.
- It is OK for some notes to stand alone. These
“loners” can be as important as others
that fit into groupings naturally.
- In some cases, you may want to reverse the
wording of the exclusions, phrasing them as items
to include, rather than as items to exclude. The
key is to make sure their essence is incorporated
into the draft and final decision.
Example
Suppose your team was assigned to come up with
recommendations for your organization’s new
cafeteria and food services. You’ve talked with
people who expect to use the cafeteria on a regular
basis, and you’ve benchmarked other local
facilities. Now it’s time to compile your ideas
and decide what proposal to make.
Figures 1 and 2 show the two affinity diagrams
your team prepared to summarize brainstorming on what
should be included and excluded in the design
proposal. There are four header categories for
inclusions and three for exclusions. Original ideas
are listed under each header.

Figure 3 shows a draft proposal that incorporates
all of the header boxes. Note that some of the
“exclude” headers have been reversed to
positive inclusions. Figure 4 shows the final
proposal, which incorporates some of the original
ideas to clarify the key components of the
recommendation.
