A lack of behavioural changes are one of the primary reasons why change projects do not realise their full benefit potential. Still, it is rare to see projects take their point of departure in the people who will be affected by the changes, and often we fail to provide these people with the proper support during the project. This makes it hard for our colleagues, clients, or citizens to change their behaviour, which is a shame, because it means that we will not get the full value out of our projects. If we include change management and behavioural design in our projects then we can elevate the effect of our development initiatives significantly. This presentation will use examples and cases to introduce a structured and practical approach to change.
