Which statement about outcomes is CORRECT?

It is important to understand the difference in these terms not just for clarity, but because outputs are much easier to measure than outcomes.

Outputs are nearly always quantitative, with data available to show whether these have been delivered. Outputs are easy to report on and to validate. There is no grey area.

Outcomes are more challenging to verify because they are both qualitative and quantitative. Whether your outcomes have been achieved will rely, to a great extent, on the perception of the people who receive the service. Perceptions are not easy to measure or report on, but it is essential you find a way to do so.
