When the company was small, the founder could hold the whole plan in their head. Every important call went through one person, and that worked because one person could see everything.
Past a certain size, that same habit becomes the ceiling. There are more people, more customers and more decisions than one person can carry. Each department gets busy on its own version of the plan. Meetings fill with discussion instead of decisions. And because nobody else fully owns the outcome, the decisions drift back to the owner.
Working harder does not fix this. It speeds things up for a while and then burns out the person at the centre. What fixes it is a shared operating system: a small set of decisions, habits and meetings that the whole leadership team runs, every week, without waiting for the founder.
It is not an ambition problem. It is a systems problem.More effort from you will not fix it. Structure will.
