Two different jobs that the same person usually does badly at the same time.
A standard distinction in corporate governance; no single originator.
Governing is deciding where the business is going and holding it to account. Managing is running it day to day. In a small business one person does both, and the urgent one always wins.
Governing sets direction, approves the plan, monitors performance against it, manages risk, and holds management to account. It is periodic, deliberate and forward-looking.
Managing allocates the work, solves today's problems, serves the customer and runs the operation. It is continuous, reactive and immediate.
There is no board, so the owner is both. Managing has deadlines and people waiting; governing has neither. So the governing simply does not happen, and the business runs perfectly well while going nowhere in particular.
This is the same failure as [the achiever matrix]'s quadrant two, seen from the top of the organisation.
