Results matter. A revenue source plan can look great on paper, but if it fails to perform, it is a waste of time and money. Organizations should make a concerted effort to regularly evaluate revenue development efforts and develop courses of action to address efforts that appear to be underperforming or not meeting expectations. Remember that, as you implement any new income strategy, it's vital to include key stakeholders from your organization, including your board, key donors, partners, and a selection of clients. Their support and feedback on strategy, timing, and costs will prove helpful in implementing your plan.
