Hi Sheik,
Thank you for replying.
Scorecard is exactly what we had opted for, as it was looking like our best bet for such data. But this visualization was rejected by the client saying that they do not want to see any data in tabular form.
Showing the status is not a challenge for us, as we could always use an icon with alerters.
The main challenge is to project the dates.
A single project could be of 2-4 years duration, and each of the 10-20 milestones could have a target date (in dd/mm/yy) anywhere throughout the project duration. Depicting a scheduled vs. actual finish date for each milestone isproving out to be a challenge.
As for your other suggestion - bullet chart - would it work in this scenario, where difference between individual milestone's dates could be far and varied? I'll try to play with it.
