Great question! In partial answer to your question, there is a commonly thrown-around figure that 5-10% of an organisation’s budget should be spent on evaluation (e.g. see INTRAC). But this is a pretty basic heuristic (indeed in the linked article they talk about a study that found a range of 0-25%). I think at a minimum all organisations should have some kind of theory of change (even if it is very basic) and should be collecting basic monitoring data to enable project management. But I think we do need more thinking and guidance around when and how you decide to do more M&E (especially the E!) and decide how to do this within your means. In other sectors this is also often driven by demand from funders too.
