Budgeting is an important tool for Managers who Lead. Think of a budget as a guide to what you can do, rather than telling you what you can’t do. Incoming funds are always more limited than the countless ways you could spend these funds, and so you must choose what you want most – what is most important for you to spend your (always limited) resources on. It works that way for personal budgets and it works that way for organizational and project budgets.
