The Invisible Network: Why Org Charts Don’t Show Where Innovation Actually Moves

In most enterprises, the formal organisation is where innovation gets recognised, but the informal network is where innovation actually travels

The Map That Isn’t the Territory

Every large enterprise has an organisational chart. It shows reporting lines, departments, functions, levels. It is the official representation of how the organisation is structured, and it is the document most leaders reach for when they want to understand how work flows.

The org chart has one serious limitation when the question is innovation: it does not show where innovation actually moves.

Across 28 in-depth interviews with innovation leaders for the Bridgium research, a consistent pattern appeared. When respondents described how successful innovations had travelled through their organisations, the paths they traced rarely matched the org chart. Ideas moved sideways across reporting lines. They jumped levels. They travelled through informal conversations with trusted colleagues, hallway exchanges, coffee meetings, and cross-functional communities that had no official status but carried enormous practical weight.

When the same respondents described innovations that had failed to move, the pattern was equally clear. The failed ideas were ones that had been pushed through the formal channels the org chart represents — presented in official meetings, escalated through approval hierarchies, documented in proper memos — and had quietly died somewhere along the way.

The insight is structural: in most large enterprises, the formal organisation is where innovation gets recognised, but the informal network is where innovation actually travels. When leaders treat the org chart as the map of innovation flow, they are looking at the wrong map.

What the Research Shows About Informal Networks

The Bridgium research is explicit about the role of informal networks in innovation flow. Across stages, the conditions that enable movement are not primarily structural — they are communicative. The framework identifies specific communicative enablers at each stage: non-hierarchical peer networks at Stage 1, cross-functional communities at Stage 2, horizontal communication channels at Stage 3.

“The most impactful part is the network — it’s guidance, it’s talking, it’s others taking the idea further.”

This observation captures what most innovation leaders know intuitively but rarely say out loud. Ideas do not move because they are approved. Ideas move because they are carried — picked up by someone who finds them useful, referenced in a conversation, adapted to a new context, passed to a colleague who needs exactly that insight for a problem they are working on. This carrying happens in networks, not hierarchies.

The academic literature supports this directly. Ronald Burt’s work on Structural Holes (1992) demonstrates that the most valuable positions in organisational networks are not the ones with the most connections, but the ones that bridge otherwise disconnected clusters. Mark Granovetter’s classic research on “The Strength of Weak Ties” (1973) showed that weak connections across groups — the acquaintances, the occasional collaborators, the people we know but do not work with closely — carry more novel information than strong ties inside tightly-connected groups.

The implication is significant. The org chart shows strong ties within departments. Innovation requires weak ties across departments. The map does not show the territory where the work actually happens.

Where the Network Does What the Org Chart Cannot

The Bridgium research identifies four specific functions that informal networks perform in innovation flow — functions that formal structures either cannot perform or perform poorly.

Network Function What Happens What Formal Structures Miss
Sensemaking Early observations tested with trusted colleagues before formal articulation Formal channels skip this layer — ideas enter the pipeline without prior sensemaking
Legitimacy testing Ideas informally filtered and refined before being presented in meetings Formal processes either over-accept or under-reject at the initial stage
Ownership transfer Others begin referring to, adapting, and integrating the idea into their own work Formal handover without network-based adoption produces surface-level ownership
Innovation Memory Knowledge of past pilots and promising directions lives in people who were there Formal documentation captures events; network carries the meaning behind them

The Three Types of Network Gaps

The most useful diagnostic move the Bridgium framework enables is asking where the informal network is broken — not where it is strong. Strong networks rarely need attention. Broken networks are where innovation flow stalls, and the breaks follow recognisable patterns.

  • Gap 1: The Structural Hole. This is Burt’s original concept applied to innovation flow. A structural hole exists when two parts of the organisation have things to say to each other but no one in the network connects them. Innovation teams and operations. R&D and field sales. Finance and product development. The hole is not in the org chart — both groups are visible, both report somewhere, both have defined scopes. The hole is in the network: no one routinely talks to people on both sides.
  • Gap 2: The Bottleneck. This is the opposite problem. One person — usually someone respected, cross-functionally trusted, and deeply informed — becomes the single node through which innovation flow passes between otherwise disconnected groups. The organisation works because this person exists, and the organisation’s innovation capacity becomes vulnerable to their availability.
  • Gap 3: The Disconnected Cluster. In this pattern, a group of people are tightly connected to each other but poorly connected to the rest of the organisation. They may be a regional office, a specialist team, a legacy business unit, or a newly acquired group. They have ideas, they do innovative work, they make things happen — but almost none of what they produce reaches the broader organisation because the connecting links are too few or too weak.
Network Gap Symptom Intervention
Structural Hole Two groups have valuable things to exchange but no one connects them Deliberate bridge-building — create connections that did not exist before
Bottleneck Innovation flow depends on a single bridge person; fragile to their availability Distribute the bridging role so capability doesn’t depend on one person
Disconnected Cluster Group innovates internally but the output never reaches the wider organisation Weak-tie development — add low-cost cross-boundary connections

Why Most Innovation Interventions Miss the Network

When organisations recognise that innovation is not flowing, the default response is to add formal infrastructure: a new innovation lab, an idea management platform, a structured pipeline process, a dedicated innovation function. These are structural responses to what is often a network problem.

The Bridgium research suggests that structural responses miss the network in three specific ways.

  • Platforms replace conversations with databases. An idea management platform captures contributions, routes them through stage-gate processes, and produces reports on submission volumes. What it does not do is replicate the sensemaking, legitimacy-testing, and ownership-transfer functions that informal networks perform. The platform becomes a database of ideas that no one has carried, while the informal conversations where real innovation used to happen are displaced by the expectation that “proper” ideas go through the system.
  • Innovation labs isolate the work. Dedicated innovation functions concentrate innovation activity in one place — which can be valuable when it comes to deep exploration, but which deepens the disconnect between the innovation function and the rest of the organisation. The network connections that would allow innovation to travel from the lab into operations often do not exist.
  • Formal pipelines override network judgement. Stage-gate processes impose a sequence: ideation, concept, feasibility, pilot, scale. At each gate, formal criteria determine whether an idea proceeds. This discipline can be valuable, but it overrides the informal judgement that networks perform continuously. Ideas that would have been refined, adapted, or redirected through network conversations are instead forced to perform against formal criteria before they have had time to develop.

Looking at Your Organisation With Network Eyes

The shift the Bridgium framework enables is a change in how innovation leaders see their own organisation. Instead of asking “how is our innovation process performing?”, the question becomes “how is our innovation network performing?” These produce different answers.

Some practical questions that shift the lens from process to network:

Who are the people in your organisation that ideas actually travel through? Not the people in the innovation function. Not the people whose job title includes the word. The people who are informally called when someone has a promising observation and wants to know if it is worth raising. These are the bridge nodes. Your innovation flow depends on them — and most organisations do not know who they are or what they need to continue doing the work.

Where are the structural holes? Which functions or business units need to exchange information but have no regular connection between them? The holes are rarely hidden from close observation — they are visible the moment you ask — but they are almost never mapped explicitly.

What happens when a bridge person is unavailable? If there is a specific individual whose connection to multiple parts of the organisation keeps ideas moving, what happens to that flow when they are on leave, focused on operations, or transitioning out of the role? The answer to this question tells you how dependent your innovation capacity is on single nodes.

Which clusters are innovating but invisible? Which groups in your organisation are producing ideas, adaptations, or improvements that never reach the central innovation function? They exist in almost every large enterprise — regional offices, specialist teams, frontline groups with deep operational knowledge.

These questions do not appear on the org chart. They appear when you start looking at the organisation as a network rather than a hierarchy — and they often reveal that the innovation problem is not a shortage of ideas or a failure of process, but a set of specific network conditions that can be directly addressed.

Conclusion

The org chart is a useful document for many purposes. Mapping innovation flow is not one of them. The Bridgium research with 28 Nordic and European innovation leaders shows consistently that ideas move through informal networks — the connections that live underneath the formal structure — and that most structural innovation interventions miss the network entirely.

Recognising this shifts the diagnostic conversation. Instead of asking “how do we improve our innovation process?”, the question becomes “how does the invisible network that actually carries innovation work in our organisation — and where is it broken?” This is a more productive question because it points toward interventions that match the mechanism. Strengthen bridge nodes. Close structural holes. Connect disconnected clusters. Preserve the informal layer even when you add formal infrastructure.
