I'm starting to roll out Advanced Roadmaps in our organisation. It's a relatively mature Jira instance so it has a number of custom fields for start/end dates depending on the context.
Are there any best practices for selecting which date fields should be used for start date / end date in Advanced Roadmaps? When I create a brand new plan it defaults to "Start Date" (custom field 12010) and "Due Date" (the in-built field).
How do others have this set up?
Are people tracking planned dates and actual dates separately? I'm thinking that's not very relevant when planning using scaled agile techniques.
