There's a practical three-step process that's been developed by social marketing experts at Griffith University in Australia that you can apply when implementing behaviour change programs. It's called "Co-create, build, engage (CBE)".
First, programs are co-created (C) with people at the heart of the problem and built (B) to create and embed lasting solutions, and finally communities are engaged (E) to partake in these programs.
The International Social Marketing Association has invited the creators of the CBE process to share how they have developed and applied it to a range of different contexts. The three speakers, Professor Sharyn Rundle-Thiele, Dr. Timo Dietrich, and Dr. Julia Carins are all experts in social marketing and behaviour change.
If you'd like to learn more, two live webinar options are available on September 8th or 9th, depending on your timezone. You can register for the webinar here, and/or read a full journal article on the CBE process here.
