3-12-3 Brainstorm

Object of Play
This format for brainstorming compresses the essentials of an ideation session into one short format. The numbers 3-12-3 refer to the amount of time in minutes given to each of three activities: 3 minutes for generating a pool of observations, 12 for combining those observations into rough concepts, and 3 again for presenting the concepts back to a group.

Essential to this format is strict time keeping. The “ticking clock” forces spontaneous, quick-fire decisions and doesn’t allow for overthinking. With this in mind, a group that is typically heavily measured in its thought process will benefit the most from this exercise but will also be the hardest to engage. Given its short duration (30 minutes total for 10 participants), 3-12-3 Brainstorming can be used as an energizer before diving into a longer exercise or as a standalone, zero-prep activity. It works equally well in generating new ideas as improvements to existing ones.

Number of Players
This is a fast exercise that gets slower as more participants are added. With up to 10 participants working as partners, the speed of the exercise makes it an energy builder. Working beyond 10 may require creating groups of three instead of pairs to keep from getting slowed down.

Duration of Play: 21–30 minutes, depending on number of participants

How to Play
You will need a topic on which to brainstorm ideas, boiled down to two words. This could be an existing problem, such as “energy efficiency,” or it could be focused on creating something new, such as “tomorrow’s television.” Although the two words could be presented as a full challenge question, such as “How
will tomorrow’s television work?” it is best to avoid doing this right away. By focusing on two words that signify the topic, you will aim to evoke thinking about its defining aspects first, before moving into new concepts or proposing solutions.

To set up the game, distribute a stack of index cards and markers to all the participants. Everyone should have a fair number of cards available. The game should begin immediately after the rules have been explained.

3 Minutes: Generate a Pool of Aspects. For the first three minutes of the exercise, participants are asked to think about the characteristics of the topic at hand and to write down as many of them as they can on separate index cards. It may accelerate the group’s process to think in terms of “nouns and verbs” that come to mind when thinking about the subject, or to free-associate. As in all brainstorming, no filtering should be put on this phase, in which the goal is a large pool of aspects in a small window of three minutes.

12 Minutes: Develop Concepts. At this point the group is divided into pairs. Each team draws three cards randomly from the pool. With these as thought starters, the teams now have 12 minutes to develop a concept to present back to the larger group. If the two topic words are sufficient to explain the challenge, the clock starts and the teams begin. If there is any doubt, reveal a more fleshed-out version of the topic’s focus, such as “How will we become more energy-efficient next quarter?” In developing concepts to present, teams may create rough sketches, prototypes, or other media—the key is in preparing for a short (three-minute maximum) presentation of their concept back to the group.

3 Minutes: Make Presentations. When presenting to the larger group, teams may reveal the cards that they drew and how the cards influenced their thinking. Again, tight time keeping is critical here—every team should have a maximum of three minutes to present their concept. After every team has presented, the entire group may reflect on what was uncovered.

Strategy
Speed is key. Many traditional brainstorming techniques can be slowed down or fouled entirely when time is not of the essence, despite the best intentions of participants. Additionally, speed helps prove the value of what can be accomplished in short bursts—often the important aspects of good ideas can be captured very quickly and do not require laborious discussion before first coming to light.

After presenting concepts back to the group, teams may do a number of things. They may dig deeper on an individual concept or try to integrate the ideas into each other. They may vote or rank the concepts to decide on which to spend more time developing. Often, concepts coming out of this exercise are more memorable to the participants, who are bonded in the time-driven stress of creating together.

WhoDo

Object of Play
The objective of this game is to identify stakeholders and clarify goals.

Number of Players: 1–10

Duration of Play: 20–45 minutes

How to Play
Who do you want to do what? Almost any endeavor of substantial impact requires seeking help from others. Developing a WHO + DO list is a simple way to scope out the undertaking.

1. Start with the vision. Write out or visualize the big goal.

2. Draw a two-column matrix and write “WHO” on the left and “DO” on the right.

3. Ask: Who is involved in making this happen? Who is the decision maker? Who has needed resources? Who may be an obstacle? Whose support is needed These individuals or groups are your list of WHOs.

4. The DOs are often harder. For each WHO, ask: What do they need to do, or do differently? What actions will build toward the big goal? Sharpen each WHO in the list until you have a desired and measurable action for each. Given all of the possible WHOs and DOs, which are the most important? Who comes first?

Strategy
Bias yourself toward action. When brainstorming DOs, there is a tendency to slip into the easier mode of “we just want them to understand.” Most often when you want people to understand something, it’s because you want them to change something or learn something that they can then “DO.” Ask yourself, or the group, “What will happen once they understand?” Don’t shortchange what you are really looking for: action. A natural follow-on to this activity is to make an Empathy Map of the WHOs.

Storyboard

VTS, originally uploaded by dgray_xplane.

Object of Play
This game asks players to envision and describe an ideal future in sequence using words and pictures. Storyboarding as a technique is so versatile that it can be used to show any topic, not just an ideal future. But it is particularly powerful as a visioning exercise since it allows players to imagine and create possibilities. The players tell a story with a happy ending, planting tiny seeds for a different future. You can also use storyboarding to let employees describe their experience on a project, to show approaches to solving a problem, or to orient new employees on policies and procedures—its uses are limited only by the imagination.

Number of Players: 8–20

Duration of Play: 45 minutes to 1.5 hours

How to Play
Before the meeting, determine the topic around which the players will craft their “ideal” story. Once the meeting starts, divide the group into pairs or groups of three or four, depending on the size of the group. Provide markers, pads of flip-chart paper, and stands.

1. Tell the players that the purpose of this game is to tell the other players a feel-good story. The topic of the story is “The Ideal Future for [blank]”—for a team, a product, the company, whatever you decided beforehand. The players’ assignment is to visually describe the topic and narrate it to the group.

2. After the groups are established, give them 20–25 minutes to (1) agree on an ideal state, (2) determine what steps they would take to get there, and (3) draw each step as a sequence of large images or scenes, one per sheet of flip-chart paper.

3. Give the players a two-minute time warning, and once the time is up, bring them back together. Ask for volunteers to tell the story first.

4. After all the groups have presented, ask them what’s inspiring in what they heard. Summarize any recurring themes and ask for observations, insights, and “aha’s” about the stories.

Alternative: Have individuals draw their storyboard images on large stickies.

Strategy
As the leader of this game, be sensitive to the fact that many of the meeting participants will freak when you tell them that large-scale drawing is involved. Reassure them that the story is the point of the exercise and that the images play a supporting role. They can use words as captions to clarify the images and they can also select the “artist” within their group so that not everyone has to put marker to paper. (But it’s more fun for those who do.) Finally, remind them that they aren’t allotted sufficient time to create a da Vinci anyway, so stick figures work perfectly well.

For the presentation format, there are various options. Breakout groups can post each sheet of flip-chart paper in a row around the room and walk along the row as they tell the story. They can also leave the flip-chart pad intact and flip the pages over the stand as they narrate. They could choose to hang the sheets in rows and cover them, using one group member to act as a “Vanna White” and create a series of voilà moments. Tell them to have fun with it—they won’t be graded on their stories (although you could make it a contest if it’s that kind of crowd). The process of creating and sharing the stories is what matters.

Walt Disney is credited for this activity. His need to animate Steamboat Willie in 1928 led to the process of storyboarding—a story told in sequence on a wall covered with a special kind of board. He found it to be an effective way to track progress and improve a story.

Post-Up

Post-up, originally uploaded by dgray_xplane.

Object of Play
The goal of this game is to generate ideas with silent sticky note writing.

Number of Players: 1–50

Duration of Play: 10 minutes to 1 hour

How to Play
There are many ways to work with ideas using sticky notes. Generating ideas is the most basic play, and it starts with a question that your group will be brainstorming answers to. For example: “What are possible uses for Product X?” Write the question or topic on a whiteboard. Ask the group to brainstorm answers individually, silently writing their ideas on separate sticky notes. The silence lets people think without interruption, and putting items on separate notes ensures that they can later be shuffled and sorted as distinct thoughts. After a set amount of time, ask the members of the group to stick their notes to the whiteboard and quickly present them. If anyone’s items inspire others to write more, they can stick those up on the wall too, after everyone has presented.

Harry Brignall at the 90% of Everything blog makes a great suggestion:

When doing a post-up activity with sticky notes in a workshop, you may want to use the FOG method: mark each note with F (fact), O (opinion) or G (guess). It’s such a simple thing to do, but it adds a great deal of clarity to the decision-making process.

Strategy
Generating ideas is an opening activity, and a first step. From here you can create an Affinity Map or further organize and prioritize the thoughts, for example using Forced Ranking.

The Post-Up game is based on the exercises in Rapid Problem-Solving with Post-it® Notes

Forced Ranking

Object of Play
When prioritizing, a group may need to agree on a single, ranked list of items. Forced ranking obligates the group to make difficult decisions, and each item is ranked relative to the others. This is an important step in making decisions on items like investments, business priorities, and features or requirements—wherever a clear, prioritized list is needed.

Number of Players: Small group of 3–10 participants

Duration of Play: Medium to long; 30 minutes to 1 hour depending on the length of the list, the criteria, and the size of the group

How to Play
To set up the game, participants need to have two things: an unranked list of items and the criteria for ranking them. Because forced ranking makes the group judge items closely, the criteria should be as clear as possible. For example, in ranking features for a product, the criteria might be “Most important features for User X.” In the case of developing business priorities, the criteria might be “Most potential impact over the next year.”

If there are multiple dimensions to a ranking, it is best to rank the items separately for each criterion, and then combine the scores to determine the final ranking. It is difficult for participants to weigh more than one criterion at a time, as in the confusing “Most potential impact over the next year and least amount of effort over the next six months.”

In this case, it would be best to rank items twice: once by impact and once by effort. Although there is no hard limit on the number of items to be ranked, in a small-group setting the ideal length of a list is about 10 items. This allows participants to judge items relative to one another without becoming overwhelming. By making the entire list visible on a flip chart or whiteboard, participants will have an easier time ranking a larger list.

To play, create a matrix of items and the criteria. Each participant ranks the items by assigning it a number, with the most important item being #1, the second most important item as #2, and so forth, to the least important item. Because the ranking is “forced,” no items can receive equal weight.

Once the items have been ranked, tally them and discuss the prioritized list and next steps.

Strategy
Creating a forced ranking may be difficult for participants, as it requires they make clear-cut assessments about a set of items. In many cases, this is not the normal mode of operation for groups, where it is easier to add items to lists to string together agreement and support. Getting people to make these assessments, guided by clear criteria, is the entire point of forced ranking.

The original source of the Forced Ranking game is unknown.

Dot Voting

Object of Play
In any good brainstorming session, there will come a time when there are too many good ideas, too many concepts, and too many possibilities to proceed. When this time has come, dot voting is one of the simplest ways to prioritize and converge upon an agreed solution.

Number of Players: At least 3 participants; in larger groups, tallying votes will be more time-consuming

Duration of Play: Short

How to Play
First, the group needs a set of things to vote on! This may be something they have just developed, such as a wall of sticky notes, or it may be a flip-chart list that captures the ideas in one place. Ask the group to cast their votes by placing a dot next to the items they feel the most strongly about. They may use stickers or markers to do this. As a rule of thumb, giving each participant five votes to cast works well.

Participants cast their votes all at once and they may vote more than once for a single item if they feel strongly about it. Once all the votes are cast, tally them, and if necessary make a list of the items by their new rank.

This prioritized list becomes the subject of discussion and decision making. In some cases, it may be useful to reflect on ideas that didn’t receive votes to verify that they haven’t been left behind without cause.

Strategy
This technique is used to collaboratively prioritize any set of items. It could be used to hone a list of features, to agree on discussion topics, or to choose among strategies and concepts. Giving participants five votes is enough to be meaningful while still asking for individual prioritization; however, this is not a hard rule.

The original source of the Dot Voting game is unknown.

Card Sort

Object of Play
Card sorting is a practice used frequently by information architects and designers to gather and structure inputs for a variety of purposes. In a common use of card sorting, information for a website is put onto the cards, and the sorting helps create categories for navigation and the overall architecture. The method works just as well for creating slides for presentations, or at any point where information needs to be sorted and organized in a sensible way.

The applications of card sorting are numerous, and in use it works similarly to Post-Up and affinity mapping. Card sorting can differ from these methods, however. First, the cards are generally prepared in advance, although participants should be allowed to create their own while sorting. Second, the cards are a semi-permanent artifact and can be used as a control over several exercises with different participants to find patterns among them.

Number of Players: Small groups or individuals

Duration of Play: 30 minutes or more, depending on the number of cards and participants

How to Play
Use 3×5 index cards or similar. For a typical sorting exercise, aim for 30–100 cards in total; more than this range will likely overwhelm the participants, and fewer may not be meaningful enough to be worth the effort. On each card should be a succinct bit of information; enough to tell the participants what it is and no more. Putting too much information on a card will slow down the sorting; not enough will cause confusion and will slow down the process even more.

Give the group the shuffled deck and a stack of blank cards. Describe the overall organization challenge, and ask them to sort the cards into groups that go together. If they think something is unclear or missing, they may alter a card or create a new one. Once they have created the groups, ask them to name them and describe them.

There are variations of sorting—including asking the group to rank the items from most to least desirable or to organize the cards into two categories such as “must have” and “nice to have.” You may also ask the group to sort cards into a predefined set of categories, to test their validity.

Strategy
Although the Card Sort game won’t tell you everything you need to know about a set of information, it will help reveal the thought process of participants. In this sense, it’s more about people than information. Only after a number of sorting exercises with a number of groups will larger patterns appear.

Card sorting is a common practice of information architects and designers of complex systems. Its actual source is unknown.

Bodystorming

Object of Play
Bodystorming is simply brainstorming, but done with the body. It may look different depending on the preparations and location, but in the end all bodystorming is fundamentally about one thing: getting people to figure things out by trying things out. A group may explore one of the techniques described below to get their feet wet with bodystorming. They may move through them in order, from observing and learning to ideation and prototyping, although this is not a strict sequence. Each level of bodystorming will help break the pattern of analyzing ideas around a conference table and get people closer to developing things that will work in the real world.

How to Play
Bodystorming takes place in three phases.

Level 1: Go Observe
Go to the location to do your work. If you are developing an idea for a coffee shop, or a shopping mall, or a hospital, go there and do your work as you would normally. The environment will present idea cues and authentic information that would never emerge from conference room brainstorming. For example, say a group is charged with improving the student experience on a college campus. Although they may conduct interviews or other research, they may start by
going to a few campus locations and “blending in” with the surroundings while going about their usual work. It’s important that the group not zero in on any specific analysis so that they will be open to the cues that the environment presents.

Level 2: Try It Out
Use role play and props to develop an idea. In this exercise, a group physically “acts out” an experience by using whatever they have on hand or can acquire. The group focuses on how they interact with each other, their surroundings, and makeshift artifacts, testing existing ideas and uncovering new ones. For example, say a small group is asked to “reimagine the evening news.” Using each other as the actors, the audience, the news anchors, and the television itself, they improvise a script that plays out the experience as they conceive it could be.

1. Identify and assign critical roles. For any experience, identifying the “customer” or “user” role is a good way to get started. This participant (or group of participants) becomes the focal point and main character of the bodystorm. Other critical roles will present themselves. “Who wants to be the Internet?” is not an uncommon question to hear.

2. Improvise the experience. Bodystorming is physical and progressive: as the group starts to put their thoughts into action, they will naturally ask simple and important questions by acting them out, often leading to the unexpected. For example, in the evening news scenario:

“OK, so how do you watch the evening news?”
“I don’t have a television. Also, I’m usually out jogging.”
“Oh. Do you have your phone on you?”
“Always. I’m listening to music.”
“OK, what if this happened… who wants to play the phone?”

In a completely improvised scenario, the group should keep in mind the principal rule of the game: building on each other’s inputs. “Yes, and…” will generate
more progress than “Yeah, but…” thinking. In some uses of bodystorming, a group will act out a script prepared in advance. In these cases, an equal amount of planning in props to build an environment is key. For example, if it’s a coffee shop, set up the counter and chairs. If it’s a park or outdoor area, strongly consider going there.

The BetaCup Bodystorming Session – Overlap 09 from the betacup on Vimeo.

Level 3: Reflect on What Happens, and Why
By enacting the experience, the participants will naturally explore new possibilities, and uncover flaws or assumptions about how an idea could work. This is valuable both in the process itself and afterward: by documenting the exercise on video, the participants may later “watch the reel” to discuss key points.

Strategy
Choose the right level of bodystorming at the right time for the group. Because bodystorming asks participants to take a big step away from the typical conference table mode of thinking, they may need to get comfortable with more structured sessions first, armed with scripts and specific roles, before stepping into complete improv. In all cases, the exercise itself will be more memorable than the customary problem-solving session, and will help generate empathy that comes from “embodying” the experience.

The term “bodystorming” was coined by Colin Burns at CHI ’94 In Boston, Massachusetts.

Affinity Map

Affinity mapping, originally uploaded by dgray_xplane.

Object of Play

Most of us are familiar with brainstorming—a method by which a group generates as many ideas around a topic as possible in a limited amount of time. Brainstorming works to get a high quantity of information on the table. But it begs the follow-up question of how to gather meaning from all the data. Using a simple Affinity Diagram technique can help you discover embedded patterns in your data (and sometimes break old patterns) of thinking by sorting and clustering language-based information into relationships. It can also give us a sense of where most people’s thinking is focused. Use an affinity diagram when you want to find categories and meta-categories within a cluster of ideas and when you want to see which ideas are most common within the group.

Number of Players: Up to 20

Duration of Play: Depends on the number of players, but a maximum of 1.5 hours

How to Play

1. On a sheet of flip-chart paper, write a question the players will respond to along with a visual that complements it. Conduct this game only when you have a question for the players that you know will generate at least 20 pieces of information to sort.

2. Ask each player to take 10 minutes to generate sticky notes in response to the question. Use index cards on a table if you have a group of four or less. Conduct this part of the process silently.

3. Collect the ideas from the group and post them on a flat working surface visible to everyone. It should end up resembling the following figure.

4. Based on guidance from the players, sort the ideas into columns (or clusters) based on relationships. Involve the group in the process as much as possible. Have the players approach the wall to post their notes—it saves time—and allow them to do an initial, general sorting in columns or clusters.

5. Create a sticky-note “parking lot” close to the display for ideas that don’t appear to fall into a natural category. Redundancy in ideas is OK; don’t discard sticky notes because they’re already represented. It’s helpful to leave repeated ideas posted since it indicates to the group how many people are thinking the same thing. At this stage, ask the players to try to avoid searching for higher categories and simply to focus on grouping the information based on the affinities.

6. Once the content is sorted, ask the group to suggest categories that represent the columns you’ve created and write the categories they agree on at the top of the column (or near a cluster if you chose a cluster rather than a column display). Don’t let the players spend an inordinate amount of time agreeing on a name for a category. If there’s disagreement over “Facilities” versus “Infrastructure,” write them both. If the players produce categories that are significantly different, pay attention to which category gets the most approval from the group and write that one. Your visual may end up looking like the one below.

Strategy

The value of the Affinity Diagram game increases when two conditions are met. The first is that the players generate multiple data points, ideally with good information. The second relates to the quality of the sorting. The cleaner the players’ insights when they form relationships within the content, the better the categories will be; only then can you discover embedded patters in your data.

Fun, optional activity: Run through the Affinity Diagram game once, complete with categorizations. Then ask the group to reshuffle the sticky

notes and recombine the ideas based on affinities they didn’t notice in the first round.

Sometimes affinities within content are crystal clear, so the sorting becomes less pivotal, but when those relationships are more nuanced, it’s more important that the sorting process is done well. In a situation in which there are many ways to affinitize information, assume a stronger facilitative role. Ask questions about the columns or clusters to clarify the group’s thinking and steer them toward an appropriate number of categories. If there are too many, the data gets watered down. If there are too few, the analysis gets watered down. Help the players find the sweet spot.

The affinity diagram was devised by Jiro Kawakita in the 1960s. It is also referred to as the KJ Method.

Lo-Tech Social_Network…Explored

Inspired by GameStorming and looking for a new content piece for a 2 day workshop I was facilitating I decided to facilitate Lo-Tech Social_Network.

And for some reason I called it Social-Network-UN_Plugged…so both are used interchangeably. Why? Because I forgot the name when I introduced the activity.

Below is a write-up created with Lo-Teach Social_Network in mind and I am calling

Social-Network Un_Plugged

Purpose

Team process of creating connections.
Getting to know others while finding similarities and developing common strengths.
Visual Representation of known and un-known connections, dependencies, and accountabilities within teams

Materials:

Flip Chart Paper or Large Roll of paper
Post-its (multi-colored preferably)
Markers or pens (the more colors the better!)

Group Size:

Can be accomplished with groups of 3 – 1000’s
For smaller groups use flip chart paper, for larger groups you are going to need a MUCH larger space and sufficient amounts of paper.

Objective:

Social-Network-Un-Plugged is effective with groups of people who know each other well as well as those who do not know each other well.

The objective is to find connections, then to continue to explore how people in the team are connected. By graphically illustrating connections people begin to feel and understand that the similarities and accountabilities are more alike than they at first thought.

Preparation:

Prior to beginning this activity with small teams; ensure that you have at least one sheet of flip chat paper/per team of 10 or less.

For team of 10 or greater I recommend using another sheet of flip chart paper for every 10 people.

If the group is large for example 100+ there are 2 variations;

1. Break the group into teams of 10 people and each team sits with their own piece of flip chart paper. Teams can be Heterogeneous (do not know each other) or Homogenous (know each-other well) the facilitator and decision maker determines this based upon the program objectives.

2. The team stays one large organizational group and a large roll of paper is rolled across an available wall. With this variation everyone is finding connections with everyone else.

Additionally you will need at least one Post-it per/person and each person will need a marker, or something to write with.

Instructions and Facilitator Script:

Hand out the flip chart paper and ensure that everyone has a post-it and a marker or pen.

If using the large group method have the paper secured to a wall.

Below is how I generally explain the initiative;

“Within this room today we all share connections, connections of managerial authority, accountabilities, backgrounds, futures, trainings, families, hobbies, etc…

It is vital that these connections grow and we see that the similarities are greater than the differences. Once we explore how similar and inter-connected we all are then we can grow and develop solutions to enhance what we are doing.

Please in the top portion on your post-it write your name, below that you are going to draw a picture of your face. Below your picture write two ‘tags’ about yourself (one word skills you possess, sometime I have them write where they were born and if they work together number of years with the agency.)

Great now place you post-its randomly on the paper. Using the markers draw lines connecting you, to other people. Label these lines what the connection is. For example one line may connect 2 people who were hired together, another may connect people who worked in the same office, and another may connect people who like to eat chocolate ice-cream. The connections do not and should not be all work related, look for hobbies, personal preferences, vacation spots, sports teams, etc…”

Allow 20-30 minutes depending upon how interactive the groups are being, with larger groups you will have to allow more time. Some people walk away and come back; it is alright if everyone is not into the activity. Once the action has calmed down lead the group in some processing and reflection.

Processing & Reflection:

Here are some ideas;

Active Processing;

Ask each person to find their post-it and count the amount of connections that off-shoot their name.

Once they find their post-it and count connections ask people to read the connections and reflect on how the connections were;

formed
broken
strengthened
changed

Following the personal reflection ask the people to forms groups of 2-3. Ask each person to share one connection for each of the following terms above (formed, broken, strengthened, changed) with the group.

Possible questions for the group;

What was your initial reaction to the challenge?

How many connections were formed?

What surprised you about the connections?

In what ways did you form connections?

Who are you connected with that you did not know you shared that connection?

What can we learn from this?

How can these ideas be brought to the office, home, community, classroom?
