CollAction is a crowdacting hub where you can take action to make the world a better place, together with many like minded individuals. The aim of this project was to improve the user experience of the existing homepage, project page and creation flow. In order to do so and avoid misalignment in this pro bono project, systems to facilitate collaboration were created; a style guide, a design system, clear agreement on conventions and channels of communication. 

The thesis was performed at strategic design agency Fabrique and aims to provide an answer to how eHealth interventions can be designed as a driver for durable behaviour change in relation to physical activity. A habit conceptualisation is proposed by starting small and adopting an identity-oriented focus. Guidelines for design were developed and an application for the issue of behaviour change in relation to physical activity was designed. For the application, tiles from the game Midora were used.
