Games for serious purposes are inherently interdisciplinary. The focus of this workflow is to facilitate co-design between experts from different disciplines, however, it can also be used by a single individual to assist or verify serious game design.
This workflow can help you with design, it is not a tool to help with game development.
How exactly you use the workflow is up to you. It can be run in as short a time as 4 hours, if you have expert support for participants. It has also formed the basis of week-long 'slow game jam' events with participants having time to reflect between each stage.
