I agree with most of the answers. Would like to add some words. The priorities are the most important. The priority of any business is developing, flourishing, enlarging, going well, etc. In simple words - earning enough money on the right time. So, the manager' first priority is the income statement sheet.
Second is, to have a good HRM, in order to appoint capable employees. And then comes structure, assignments, reporting, measures.
If the first priority comes first ( in most of the case), all will know the direction and parts will work together. In short, not you to stay on the top of the moving part, but the First priority of your business.
all the best
