Kimon, There are at least 2 approaches. Let me point out 2 of them: One that formalizes the concept of tracking by starting with a definition. I would call this top - down. The other is finding out which phenomena are problematic and relevant. I would call this bottom up. The top - down approach needs a shared definition of tracking. The bottom - up approach does not need this at all.
