Imagine four people on the same railway platform as a train approaches. One moves forward after hearing an announcement, another steps back after seeing a warning signal, a third walks away because he was told the train was cancelled, while the fourth boards because he sees everyone else getting on. Each acts rationally according to what they believe is happening, and each has something making their version credible. Yet four rational actions can produce failure when there is no shared reality.
Now imagine the train leaves, and all four defend what they did. Each has evidence and an explanation, and none needs to be irrational. Yet they have acted on four different versions of the same event, each convinced their reality was obvious. This is exactly what happens when people share a workplace but not a reality.
We often assume disagreement means different facts. So we add information, expecting disagreement to disappear. But the same facts can produce different conclusions when filtered through different histories. Information can be shared without reality being shared.
Finance may see exposure where Commercial sees opportunity, while Operations sees disruption. Each may be grounded in something real. The problem begins when each becomes the reality against which others are judged. An organisation can have abundant information and still lack common understanding.
Every function develops its own memory. Past decisions and consequences shape what people notice and trust. Over time, interpretations stop feeling like interpretations and begin to feel like facts. They become invisible assumptions about reality itself.
That is why the same strategy can sound like progress to one group and danger to another. The words are shared, but meaning is not. People act from different versions of the same situation without recognising the difference. Fragmentation begins when local interpretations overpower organisational coherence.
The answer is not to make everyone see the same thing. Different perspectives reveal different parts of reality. The question is whether those perspectives can form a coherent whole that the organisation can recognise. Coherence does not erase different realities; it relates them.
Once this becomes visible, many failures look different. Strategy can drift without poor design, communication can fail despite clear words, and execution can diverge without resistance. Beneath behaviour may be several realities operating at once. The deepest fracture may occur when people no longer recognise they are looking at the same world.
