I'm trying to submit this for Advanced Roadmaps - Cloud but can't seem to find the JPOCLOUD project. 

Problem

Today, I can create multiple roadmap scenarios (e.g. worst case, best case, etc.). However, a common need (both for my own and my company's interest) is to actually compare two scenarios - i.e. what is the actual difference in delivery dates/working timelines if we go with Plan A vs Plan B. 

Solution

As a user, I can choose two or more scenarios to compare, issue by issue. This action should generate a report which contains the union of all issues present on the scenarios. The issues should be plotted along a timeline with alternate timelines for each issue represented, for example, by color, opacity, etc. The report should be sorted based on the order of the issues shown on the first scenario selected for comparison (i.e. even if scenario two has an issue much further down, the sort order should respect wherever that issue falls in the vertical hierarchy based on scenario one).

The report should include, at the issue-level, a clear indication of changes in the following fields:

• Start date
• End date
• Duration
