At the beginning, roles often exist in principle but not in practice. Titles are assigned, but the boundaries between them remain informal. Responsibilities overlap, shift, and are implicitly renegotiated as the company evolves.
This can work in the very early stages, when everything is fluid and execution speed matters more than structure. But as pressure increases, that same flexibility becomes a source of ambiguity rather than agility.
Without clearly defined roles, accountability becomes interpretive.
When something goes wrong, there is no stable reference point for who owns which part of the system. Product delays can be interpreted as leadership issues. Technical issues can be reframed as strategic or commercial failures. Commercial underperformance can be attributed to product readiness.
In other words, the system begins to self-rewrite responsibility depending on the narrative that emerges under pressure.
This is not usually intentional. It happens because expectations were never explicitly written down in a way that could be referenced when uncertainty appears.
The result is that subjective interpretation replaces objective ownership.
The solution is not to over-formalise early-stage teams, but to introduce enough clarity that responsibility does not shift depending on the conversation.
This means explicitly defining ownership boundaries for core areas such as product delivery, technical execution, commercial activity, and operational management. Not just in terms of titles, but in terms of expectations: what decisions each role is responsible for, what outcomes they are accountable for, and where decision rights begin and end.
The key shift is moving from implied understanding to written agreement.
Once roles are clearly defined, disagreements change in nature. Instead of arguing about blame, teams can identify whether the system behaved as expected within the agreed boundaries.
This doesn't eliminate tension, but it removes ambiguity from the source of that tension. And in early-stage environments, ambiguity is often what turns operational challenges into interpersonal ones.
Clear roles do not prevent problems. They prevent problems from becoming misattributed.
