When an Idea is created the system links all defined workflows and their respective stakeholder role to the Idea, as a result, should there be changes made to the Idea definition after the Idea was created i.e. adding a new Role or deleting an existing role. The changes will not be immediately reflected in the Idea.
Workflow changes after the respective Idea workflow as been submitted for approval will not be reflected on the Idea Workflow i.e. adding an extra question etc.
