opinion only - Canon DPP is a decent product and if it's what you've got, then use it. There are alternatives and many of the vendors provide trial downloads so you can see if they make a difference to you.
Fwiw, this is the workflow I use today.
1. Pull the cards from the cameras and load them into a Lexar FW800 card reader. Copy all the raw files directly from the card into a folder on a disk attached to the computer.
2. Immediately make a copy of the folder onto another disk attached to the computer, disk meaning a powered disk never a DVD.
3. Force a start of an immediate Crashplan cloud backup even though I know that one will run that night at 1am. Yes this is an unabashed plug (and uncompensated) for Crashplan.
4. Launch Lightroom and import the files using the Copy as DNG option and applying a metadata preset to load copyright information (personal choice). I choose to copy as DNG because the format is open, i don't lose anything, and I can then use the files with Colour Checker Passport amongst other utilities.
5. Wait until it's time to do post-processing and then go at it, starting with vicious editing. (The pro I apprenticed to nearly 30 years ago beat it into me that if I wasn't rejecting over 80% I was lying to myself). Do basic edits in Lightroom popping out to the Nik suite as necessary, Photoshop increasingly rarely.
6. Decide what I want to do with the images, print, web, whatever.
Not suggesting my workflow is better than someone else's. It works for me. Until I change it. You'll note the emphasis on backing up and redundant copies. Storage is cheap, reshoots are not.
