My design team are starting to use Jira to manage their non-software design work. Each work item has a period of design, review, amends, review, amends, approval. These seem to make sense as stages in Portfolio, but the review stages would be done by the customer. Should I just create a stage for this and assign it to a dummy customer team member with only one skill of 'review'? It's early days for the team starting to investigate Agile ideas so I appreciate this isn't a very Agile approach.
