Explain the Importance of strategic planning in Non Profit making organizations?

In non-profit organizations, the source of revenue is severely limited - to charitable donations, governmental funding, etc. Because of this limitation, funding the activities of the organization is very difficult, especially if they have adopted a poorly thought out strategy and thus end up wasting a significant portion of their funds. Most non-profit organizations already know what they will be doing, but they need to decide what steps they will take, and how best to take those steps. Thus they still have the majority of what is important in strategic planning (the only part not needed is discussion about what their goal is in general).
