We mapped existing initiatives against Nebuli’s list of 28 barriers to change we have identified through our internal research and experience. This enabled us to explain the underlying factors at a granular level. With this mapping process, we built a behavioural change algorithm that would allow Greater Western Water to consider the following simple metrics model: if you want to achieve x, then perform y and z. This model is based on understanding how well we can attribute behavioural change to specific activities and the ability of the targeted audience to overcome known barriers and incite the desired action.
