Workload characterization is super important because it lets us figure things out. Many people know, for example, that with Microsoft Word, Word.exe is the executable. Everybody knows their executable, but they don't always know what it does. It also launches other things. This tool has the ability and insight to track those things, and to know: "Oh, you wanted this executable, but this one started this, so you must want this, too." And it tells you what it had to add, what it was using or was spawning.
