When Words Fail, Models Speak - Using LEGO Serious Play (LSP) to Surface Unspoken Dynamics
Picture a leadership team at a retreat. They’re navigating significant changes within their organization. The team is smart, committed, and deeply familiar with the challenges ahead. A skilled facilitator is guiding the conversation. The agenda is well-designed. And yet, something is off. The discussion is articulate and somehow airless. People are speaking in complete sentences and producing no new insights. By the end of the day, the flip chart paper is covered in language everyone agreed to and almost no one fully believes. They leave the retreat and never pick back up on the conversations or the flip chart.
This is not a failure of intelligence or even intention. It is a failure of medium.
When organizations face genuine complexity, change, or conflict, the dominant container for conversation, structured verbal dialogue, consistently underperforms. Not because people don’t have something to say, but because the conditions of the room make it nearly impossible to say it. Status, history, and relational risk don’t disappear when a facilitator opens a meeting. They shape everything, often before anyone speaks.
LEGO Serious Play (LSP) (LSP) operates from a different premise. Rather than asking people to find the right words for what they know, it asks them to build it. And what gets built in those rooms is frequently the most honest organizational data available.
The Structural Problem with Language-Based Conversation
Chris Argyris spent much of his career studying why organizations, populated with intelligent people who genuinely want to improve, so reliably fail to learn. What he found was not a deficit of information or willingness, but a set of learned social behaviors he called defensive routines: sophisticated, often unconscious strategies for avoiding the kind of direct engagement that might expose error, embarrassment, or conflict (Argyris, 1990). These routines are not aberrations. They are cultivated over time by organizational systems that reward the appearance of competence and punish vulnerability.
Edgar Schein, writing about the deep structure of organizational culture, observed that what gets communicated in any group is shaped as much by the implicit rules of the social system as by the intentions of the people in it (Schein, 2010). Positional authority reorganizes who speaks, in what order, with what confidence, and on which topics, long before a single word is spoken. Amy Edmondson's foundational research on psychological safety demonstrated empirically that even in teams where members theoretically understood they were free to speak, they frequently did not, because the cues they received from leadership behavior made the risk feel too high (Edmondson, 1999).
The problem, in other words, is structural. And a structural problem can’t be resolved by a better question or a warmer room. It requires a different architecture for the conversation itself.
What LEGO Serious Play (LSP) Actually Offers
LEGO Serious Play (LSP) was developed in the late 1990s as a facilitation methodology grounded in Seymour Papert's theory of constructionism: the proposition that people learn, and come to know, most powerfully when they are actively building something shareable (Papert, 1980). The methodology formalizes what educators and cognitive scientists suspected, that the hands carry knowledge the mouth cannot yet reach, and that the act of construction is itself a form of inquiry.
The structure of a LEGO Serious Play (LSP) session is not improvisational. Participants are given a question and a set of bricks and asked to build a model that represents their response. Importantly, every person builds, every model is shared, and every model receives the same quality of attention. There is no option to defer to the most senior person in the room, or to wait for consensus before contributing, or to offer a verbal observation that can be walked back later. A built model is harder to disown than a carefully hedged sentence.
George Brown and Paul Duguid observed that knowledge is not simply stored in minds and retrieved on request; it is embedded in practice, in relationships, and in the material world (Brown and Duguid, 2000). Lev Vygotsky's concept of the mediating artifact, objects that stand between persons and ideas and allow for a different quality of engagement with both, explains something important about why the model changes the conversation (Vygotsky, 1978). When a person's perspective is externalized as a physical object, it becomes possible to examine, revise, and compare it with other models without the same ego cost that accompanies a stated position. The object holds the idea at a useful distance.
This is not a soft or therapeutic observation, but a structural one. The methodology flattens hierarchy by creating a social contract in which every participant's built model carries equivalent legitimacy. In rooms where positional authority routinely determines whose ideas count, this is a meaningful intervention.
What the Models Surface
What makes LEGO Serious Play (LSP) especially valuable is not that it produces different content, though it often does, but that it produces different kinds of content. The metaphors people choose when they build are not decorative; they are diagnostic. George Lakoff and Mark Johnson demonstrated that abstract understanding is structured by physical experience, that concepts like power, stability, connection, and threat are not processed in purely linguistic terms but are grounded in embodied sensory and spatial knowledge (Lakoff & Johnson, 1980). When someone builds a model and describes it as a house with no doors, or a bridge that keeps collapsing, or two structures that can see each other but cannot touch, they are not speaking poetically. They are giving you access to how they understand their organizational reality.
This is the territory that standard facilitation routinely fails to reach. Ikujiro Nonaka and Hirotaka Takeuchi distinguish between tacit knowledge, the felt, embodied, often pre-verbal understanding that guides expert judgment and lived experience, and explicit knowledge, the formalized, articulable content that can be documented and transmitted (Nonaka & Takeuchi, 1995). Most organizational conversation operates almost exclusively in the explicit register. LEGO Serious Play (LSP) creates a legitimate channel for tacit knowledge to become visible.
In practice, this means that a team building models of how they experience the organization right now, or what change feels like from where they sit, will produce remarkably different information than the same team answering those questions in a structured discussion. The physical positioning of figures, the relative size and stability of structures, the way a person describes their model's most fragile element: these are data. Not soft data. Organizational data that is difficult to access through any other method.
An illustrative example, drawn from composite experience: a senior leadership team undertaking a significant institutional restructuring was asked, during an LSP session, to build models representing their understanding of what the change was actually for. When the models were shared, it became apparent that the eight people in the room held at least five substantially different theories of the change's purpose. None of this divergence had surfaced in months of planning meetings. The conversation that followed was more honest, and ultimately more useful, than anything that had occurred in the formal process.
When This Approach Is Most Necessary
LEGO Serious Play (LSP) is not a universal prescription. It is a specific tool for specific conditions, and it is worth being honest about what those conditions are.
It is most valuable when a team is circling the same conversation without moving, when there is visible tension between what an organization says it values and how it actually operates, when a change process has produced compliance without generating genuine commitment, or when structural conflict is being managed around the edges rather than addressed at its center. These are, not coincidentally, among the most common conditions that leadership teams present.
William Bridges, in his work on organizational transition, drew a distinction that has not lost its relevance: change is situational and external, while transition is psychological and internal (Bridges, 2009). Organizations invest enormously in managing the logistics of change, the timelines, the communications, the structural decisions, and comparatively little in creating legitimate space for the interior experience of it. LEGO Serious Play (LSP) is one of the few methodologies designed to work in that interior space without requiring people to perform emotional disclosure they are not ready for. The model holds what people cannot yet say.
Ronald Heifetz's framework for distinguishing adaptive from technical challenges is also relevant here (Heifetz, 1994). Technical problems have knowable solutions that can be implemented by people with sufficient expertise. Adaptive challenges require people to change their own behavior, assumptions, and values, and they resist technical solutions precisely because the solution requires the people with the problem to do the changing. Most significant organizational challenges are adaptive, at least in part. And adaptive work cannot happen in rooms designed for technical discussion. It requires containers that create enough safety and enough honesty for people to see their own assumptions clearly.
The methodology also has something specific to offer in conditions of conflict, particularly the kind of low-grade, sustained conflict that organizations often manage rather than resolve. When two parts of an organization have competing interests, or when a leadership team carries unresolved disagreement about direction or values, verbal conversation is frequently not the right first container. The stakes of saying the wrong thing are too high, and the social management of the interaction produces heat without light. A building exercise creates enough distance from the live nerve of the conflict to allow the actual shape of the disagreement to become visible.
After the Models Are Built
The value of a LEGO Serious Play (LSP) session is not fully contained in what gets built. It is produced in what happens next: the comparison of models, the identification of patterns, the development of shared landscape models that represent how the group collectively understands a challenge or a question. This is where organizational insight is generated, not from any single person's model, but from the texture of what is shared, repeated, absent, and contradictory across the room.
Karl Weick's work on sensemaking in organizations is useful here. Weick argued that organizations do not simply respond to environments; they enact them, that the process of making sense of a situation is itself constitutive of the situation (Weick, 1995). An LSP session is a structured sensemaking intervention. When participants build, share, compare, and develop their models together, they are not just communicating existing understanding; they are constructing a new shared map of their organizational terrain. That map is more robust than any document or decision because it was built, not received.
This does not mean that the session resolves the tensions it surfaces. It should not try to. One of the most common errors in facilitation, of any kind, is the impulse to move from surfacing a difficulty to resolving it before the difficulty has been adequately seen. LEGO Serious Play (LSP) is most valuable when it is designed to create shared legibility, a condition in which people can see each other's actual frameworks and disagree more productively because the architecture of the disagreement is now visible, rather than subterranean.
What changes after a well-designed LSP session is not usually the content of the challenge. What changes is the relationship of the team to the challenge, and to each other. People bring a different level of understanding to the work when they have seen what their colleagues actually built.
Return to the room at the beginning of this piece. The team was not failing because they did not care or did not know things worth saying. They were failing because the form of the conversation made it nearly impossible to say what they actually knew. The words were available. The container was not.
Designing conversations that are adequate to the real complexity of what organizations face is not a minor logistical concern. It is a form of strategic leadership. When leaders choose to create conditions for genuine inquiry rather than managed agreement, they are making a statement about what kind of organization they are building, and what they believe their people are capable of contributing to it.
The bricks are just the beginning of that conversation.
Working with transform.forward
We work with leadership teams who are ready to go beyond the familiar patterns of organizational conversation. That work takes different forms depending on what a team actually needs. Sometimes it begins with a LEGO Serious Play (LSP)-facilitated session designed to surface what has been circling beneath the surface of a planning process or change initiative. Sometimes it unfolds over time through leadership team retreats that build the relational and structural conditions for more honest collective work. And sometimes it looks like team coaching, a sustained engagement that helps a group develop the habits, trust, and shared language that generative conversation requires.
If any of this feels familiar, we would genuinely enjoy a conversation. Reach out to start a conversation about what your team needs.
