I am looking for the best product to use for creating a product roadmap that will will display as a timeline so I can track changes over time.
To be more specific, I am tracking the changes across several models of computer systems. I need to break each model down into its parts (ie CPU, video card, RAM, etc...) and then display the changes of those parts (BIOS updates, chipset changes, etc...) over time on a gantt type chart. I currently do this on an excel spreadsheet but it is a very manual process. I am looking for a more automated way to handle it.
