Why a logic model helps clarify assumptions
Launch library · evergreen read
A logic model sets out, usually as a simple diagram, the chain from resources and activities through to outputs, outcomes and ultimate impact, making a campaign's underlying assumptions visible in a way that they often are not when left implicit and never actually written down anywhere the whole team can see it.
Building a logic model forces a team to be specific about exactly how each activity is expected to lead to change, which frequently reveals weak or missing links that would otherwise have gone unexamined until much later in a struggling, underperforming campaign, when time and options have both narrowed.
Once built, a logic model becomes a useful reference point throughout a campaign, giving the team a shared way to check whether new activities genuinely connect to the intended outcome or have quietly drifted from the original underlying plan somewhere along the way, without anyone quite noticing at the time.
