Having clarity on the problem you are trying to solve, why your project is a good solution and how you will know if it has been effective is critically important for your own organisational planning – and for the support of funders.

We also go through some of the often-used terminology when it comes to impact and evaluation, including ‘outcomes’, ‘outputs’, ‘logic model’ and ‘outcome indicators’.
