What is it?

Forced Connections is a creative thinking technique that breaks habitual thought patterns by making people draw links between their challenge and something entirely unrelated. You give the group a random object, image, or word, ask them to list its attributes, and then force connections between those attributes and the problem they are trying to solve. The result is a room full of people making leaps they would never make through logical brainstorming alone. It feels strange at first, and that strangeness is the point. The best ideas from this technique often start as the most ridiculous-sounding connections.

Also Known As

• Random Input
• Forced Analogy

When to Use It

• When a group has been brainstorming on a problem and has run out of steam or keeps circling the same ideas
• When you need to push past incremental thinking and generate ideas that feel genuinely different
• When participants are too close to a problem and need a way to see it from an outside angle
• When redesigning a product, service, or process and you want options beyond the obvious improvements
• When the group is comfortable with each other and ready for something that feels a bit unconventional
• As a second or third ideation round after more traditional brainstorming has captured the low-hanging fruit

When NOT to Use It

• When the group is new to each other and not yet comfortable looking silly. The technique requires people to say things that sound absurd, and self-conscious groups will hold back.
• When you need precise, evidence-based solutions rather than creative leaps. This is a divergent tool, not a convergent one.
• When the problem is straightforward and already has an obvious solution. Using Forced Connections on a simple logistics question wastes the group's goodwill.
• When there is no time for a proper debrief and development phase. Raw forced connections are wild ideas that need refining. Without that step, people leave feeling like they played a game with no outcome.
• When participants are under high stress or pressure. The playful, lateral nature of this technique clashes with urgency.

Forced Connections was formalised by Don Koberg and Jim Bagnall in their 1972 book The Universal Traveler: A Soft-Systems Guide to Creativity, Problem-Solving, and the Process of Reaching Goals. They called their version "Morphological Forced Connections" and built it on earlier work by Fritz Zwicky at Caltech in the 1960s, who developed morphological analysis as a method for systematically exploring all possible solutions to a problem. Edward de Bono's work on lateral thinking, particularly the "random input" technique, shares the same underlying principle of using unrelated stimuli to disrupt habitual thought patterns. The technique has since been adopted and adapted across design thinking, innovation consulting, and creative problem-solving programmes worldwide.

What You Need

Group size: 4 to 30 people. Works best with 8 to 20. Below 4, you lose the energy of diverse perspectives. Above 30, the sharing rounds become unwieldy unless you keep groups small and skip whole-group sharing.

Time required:

• 30 minutes minimum for a single round.
• 45 to 60 minutes for two rounds with development time.
• 90 minutes if you want multiple stimuli and a full idea selection process.

Space:

• Room with tables for small groups of 3 to 5 people
• Wall space or easels for posting ideas
• Enough room for people to move between tables if doing multiple rounds

Materials:

• A collection of random stimulus objects (physical items, printed images, or word cards). Bring at least one per table, ideally three to five options.
• Flip chart paper or A3 sheets (one per table)
• Markers in multiple colours
• Sticky notes
• Timer
• A clear problem statement written on a flip chart or projected on screen

The Process

Setup

1. Prepare your stimulus collection in advance. Physical objects work best because people can hold, turn, and examine them. Good options include: household items, toys, tools, kitchen gadgets, natural objects, or magazine images. The more unrelated to the problem, the better.
2. Write the problem statement or "How might we..." question on a flip chart and place it where everyone can see it.
3. Set up tables for groups of 3 to 5 people with flip chart paper and markers at each.
4. Place stimulus objects in a bag or box out of sight. If using images or word cards, have them face down.

Step 1: Frame the Challenge

Time: 5 minutes

Purpose: Everyone needs to understand the problem before they can connect random elements to it.

1. Present the problem statement to the group. Read it aloud and check that everyone understands it.
2. Allow 2 minutes for questions about the challenge. Answer factual questions but do not let the group start solving yet.
3. Say: "We are going to use a technique that will feel odd at first. I am going to give each table a random object that has nothing to do with this challenge. Your job is to find connections between that object and our problem. The stranger the connection, the better. There are no wrong answers here."

Step 2: Introduce the Stimulus

Time: 5 minutes

Purpose: The random element is what forces the brain out of its usual tracks.

1. Hand each table a different random object (or ask one person from each table to pick from the bag without looking).
2. Say: "Take a minute to examine your object. Turn it over, play with it, think about it. Then write down as many attributes as you can. What does it look like? What does it do? How does it feel? What is it made of? What does it remind you of? How does it move? Aim for at least eight attributes."
3. Give groups 3 minutes to list attributes on their flip chart paper. One person writes while others call out ideas.

Watch for: Groups that list only physical attributes (colour, size, shape). Prompt them to think about function, behaviour, and associations too. Ask: "What does it do? What is it used for? What does it remind you of?"

Step 3: Force the Connections

Time: 15 to 20 minutes

Purpose: This is where the creative leaps happen. Each attribute becomes a lens for looking at the problem differently.

1. Say: "Now take each attribute and ask yourselves: how could this connect to our challenge? If our product/service/process had this quality, what would that look like? Write each connection on a separate sticky note."
2. Walk through one example with the whole room first. Pick an attribute from one table and model the connection out loud. For instance, if the object is a rubber duck and one attribute is "floats," you might say: "What if our onboarding process floated, meaning it adapted to whatever situation the new starter was in rather than following a fixed path?"
3. Set the timer for 12 to 15 minutes and let groups work. Each table should aim for at least 10 connections.
4. Encourage wild ideas. Say: "If it sounds ridiculous, write it down. We will sort later."

Watch for:

• Groups that censor themselves or dismiss ideas as too silly. Remind them: "The point is to go where your brain would not normally go. Write it all down."
• Groups that get stuck on one attribute. Encourage them to move on to the next one and come back later.
• One person dominating. Ask the writer to rotate or suggest everyone writes their own sticky notes.

Step 4: Share and Build

Time: 10 to 15 minutes

Purpose: Hearing other groups' connections sparks further ideas and reveals unexpected patterns.

1. Ask each table to pick their three most interesting connections. Not the safest, not the most practical. The most interesting.
2. Each table presents their three connections in 2 minutes. Display the sticky notes on a shared wall as they present.
3. After each presentation, give the whole room 30 seconds to write any new ideas triggered by what they just heard. These go on fresh sticky notes and are added to the wall.

Watch for: The temptation to evaluate ideas during this step. If someone says "That would never work," redirect: "We are still generating. We will evaluate in the next step."

Step 5: Develop the Best Ideas

Time: 10 to 15 minutes

Purpose: Raw forced connections need shaping before they become actionable.

1. Ask the group to walk up to the wall and silently read all the ideas. Give them 2 minutes.
2. Use dot voting to identify the top 5 to 8 ideas. Give each person 3 dots and say: "Vote for the ideas that excite you most, even if you are not sure how they would work yet."
3. Take the top-voted ideas and assign one to each table. Ask them to spend 5 minutes answering: "What would it take to make this work? What is the kernel of a real idea inside this wild connection?"
4. Each table shares their developed idea in 1 minute.

Closing

Time: 5 minutes

1. Capture all developed ideas on a single flip chart with clear owners and next steps.
2. Acknowledge the group's willingness to think differently. Say: "Some of the best innovations started as ideas that sounded absurd. The fact that you pushed past the awkwardness means we now have options we would never have found through normal brainstorming."
3. Agree on what happens next: who will take the top ideas forward, when they will report back, and how the ideas will be tested or developed further.

Facilitator Guidance

What Makes This Work

Forced Connections works because of a principle called "lateral thinking." When you brainstorm normally, your brain follows well-worn neural pathways and lands on familiar ideas. A random stimulus forces you off those pathways. Your brain has to make sense of something that does not fit, and in doing so, it creates new connections it would never have made on its own. The technique also lowers the stakes for creativity. Because the starting point is deliberately random, people feel permission to say things they would normally filter out. Nobody expects a rubber duck to lead to a breakthrough, so there is no pressure to be brilliant. And that is often exactly when brilliance shows up.

Common Pitfalls

• Choosing stimuli that are too related to the problem: If you are working on a technology challenge and you bring in a laptop as your random object, people will stay in their usual thinking patterns. Pick objects that have nothing to do with the domain. Kitchen utensils, children's toys, natural objects, and hardware shop finds all work well.
• Skipping the attribute-listing step: Some facilitators hand out objects and go straight to "connect this to the problem." Without the attribute list, people only make surface-level connections. The attributes create multiple entry points for creative thinking.
• Not modelling the process first: The leap from "rubber duck" to "adaptive onboarding" is not obvious to most people. Walk through one example slowly before asking groups to work independently.
• Allowing evaluation too early: The moment someone says "that is not realistic," the creative energy drops. Be firm about keeping divergent and convergent phases separate.
• Giving up after one round: The first round often produces the wildest but least developed ideas. A second round with a different stimulus, or a development round on the best ideas from round one, produces the real value.
• Using the technique in isolation: Forced Connections works best as part of a broader ideation process. Start with conventional brainstorming to capture obvious ideas, then use Forced Connections to go further. This way the group does not feel like the wild ideas are replacing the practical ones.

Adaptations

• Virtual delivery: Use a random image generator or prepare a slide deck of random images. Share one image per breakout room. Use a digital whiteboard for attribute listing and connection-making. The technique translates well to virtual as long as you keep the energy up and model the process clearly before sending people to breakout rooms.
• Larger groups (20+): Keep table sizes at 4 to 5 and run the sharing round as a gallery walk instead of presentations. Each table posts their top connections on the wall and everyone walks around reading and adding new ideas on sticky notes.
• Shorter timeframe (15 to 20 minutes): Skip the sharing round. Have each table do one round of connections and then immediately develop their single best idea. You lose cross-pollination but still get the lateral thinking benefit.
• Multiple stimuli: For a longer session, give each table a different stimulus and then rotate them every 10 minutes. Fresh stimuli trigger fresh connections and prevent groups from getting stuck.
• Word-based version: Instead of physical objects, use random word cards. Write 30 to 40 unrelated nouns on cards, shuffle them, and deal two or three to each table. This is lighter to prepare and transport but loses the tactile engagement of physical objects.
• Image-based version: Use a curated set of photographs showing diverse scenes, animals, landscapes, machines, or art. Images often trigger emotional and sensory associations that objects and words miss.

Real-World Applications

Product innovation for a kitchen appliance company: A product team stuck on incremental improvements to a blender used a tennis ball as their random object. The attribute "bounces back" led to the idea of a self-cleaning cycle that reversed the blade direction, turning cleaning from a chore into a one-button feature.

Service redesign in a hospital outpatient department: A team working on reducing patient wait times used a Swiss Army knife as their stimulus. The attribute "multiple tools in one compact package" led to redesigning the reception process so that one interaction captured registration, insurance verification, and initial triage simultaneously rather than as three separate queues.

Marketing campaign for a financial services firm: A marketing team brainstorming new campaign concepts used a child's kaleidoscope. The attribute "same pieces, different pattern every time" inspired a campaign showing how the same savings tools could create different retirement lifestyles depending on how you combined them.

School curriculum development: A group of teachers redesigning a science curriculum used a bag of LEGO bricks. The attribute "connects to other bricks in multiple ways" led to a modular curriculum design where any unit could connect to any other unit rather than following a fixed linear sequence.

Charity fundraising strategy: A nonprofit team looking for new fundraising approaches used a pair of binoculars. The attribute "makes distant things feel close" led to a campaign that paired each donor with a specific beneficiary through monthly video updates, making the impact of their donation feel personal and immediate.
