This document provides guidance on developing an objectives tree as part of preparing a funding proposal. It begins with an example problem tree focusing on frequent flooding and water/sanitation issues in Valenzuela, Philippines. The problem tree identifies direct and indirect causes of the problems. The document then explains how to transform the problem tree into an objectives tree by reversing the process - potential solutions to each cause become the elements of the objectives tree. Objectives trees help organize the contents of a proposal by relating activities, inputs, and outcomes to objectives and broader development goals. The example objectives tree corresponds to the previous problem tree discussed. Developing clear problem and objectives trees is an important part of preparing an effective funding proposal.
