Baz, there are different types and uses of sharpening within the image editing process. There's a really good, but really long, sticky thread on POTN about it here. If you're serious about it, I recommend you take the time to read it one day or two.

Is short, they talk about capture sharpening, creative sharpening, and output sharpening.

Capture sharpening is done first, pretty much at RAW conversion stage, and just tightens up the image a little from some of the softness the camera's anti-aliasing filters may have introduced etc. Pretty sure this is the sharpening that DPP does.

Creative sharpening is done during your detailed post-processing. You might spend a bit of extra time sharpening locally a model's eyes for portraits for example. They use edge masks, sharpening layers, and all sorts of tricks for this.

Output sharpening is done last. And I mean last. After you have finished your image editing completely, saved the full sized version, and resized it for web. This is what Mike is talking about above. It's because you lose sharpness every time you resize an image.
