The design system was built using the Digital Collaboration Division's existing agile development method. Following our two-week development sprint model, we decided to start separate design sprints on the same cycle. Every two weeks we would pick a particular theme (i.e. typography, forms) to work on.
Pieces were first identified using a handy parts checklist and then listed as separate issues in Github. We managed tasks using an online Kanban board. When files were completed we uploaded them to our Github repository so that they were easily accessible to all members of the team and other partners.
On an ongoing basis, work for the design system will be integrated into existing development cycles within the Digital Collaboration team.
