What is the question you are asking
I'm pretty sure the answer would be a budget? A good budget is a way you can keep track of your money. Like what you are spending it on in different categories (like bills, entertainment, food, etc) and how much money is being spent in each.
Not really, the budgeted performance is like an expectation of a work, which is still uncertain until the result comes, in other words, an opinion on a work; while the past performance was the fact, which came from the employee's work in the past few months. To judge the fact is better than an uncertain picture.
