A couple of days ago I talked a little bit about how we want the core mechanic of the game to be the interaction between the DM and the player. And one of the great tools for that is the ability score. So what we want is to empower DMs and players so that if you want to attempt to do something "I want to open the door" then the DM doesn't have to even have you roll, he can just look, see you have a 17 strength and says "Yeah, you burst through that door". We want to get past some of the mundane rolls and not tie up a lot of table time with that and move on to the more interesting stuff and the table narrative.

I’m intrigued by this idea. My most recent thinking about test resolution had me considering dropping ability scores altogether, as was done in the CRPG, Skyrim. But this concept, outlined by Mr. Cook, seems to be a cool way to make a system with set difficulty classes work.
SpydersWebbing uses these set DCs in his 4e mod:
Anything over Moderate on such a scale would require a skill check with a roll. But many tasks could automatically be accomplished by the strongest, smartest, most-agile, or most-perceptive member of the party.
In a system without automatic leveling of skills — where skill increases were selected by the player as experience rewards for leveling, for example — set DCs make sense, and work well with the ability score-based resolution suggested by Mr. Cook. If a locked, wooden door has a break down DC of 12, a player with a strength of 12 or greater would pretty much always be able to break it down (barring unforeseen circumstances as determined by the DM.)
The balance of an RPG seems to rest on the transition point between narrative-based resolution and game-mechanical resolution. Too much narrative and the game may feel wishy-washy to some players. They may have a sense that it is arbitrary. Too much emphasis on the mechanical — rolls for nearly everything — and the game becomes a console-based CRPG. Just spam the X button until the monster is dead.
So, what happens when a character with an ability score of 18 is confronted with a task with a DC of 19? We transition abruptly from automatic success to a roll-based probability of success. But, what does that mean in narrative terms? I believe this is where the element of risk should come into play. Consequences should be discernable. Perhaps not easily so, but nonetheless, it should be the case. For example, a lock with a DC of 18 is a mechanism that an heroically-agile rogue could pick. But a lock of DC 19 would most likely include a consequence for failure. Perhaps it is a trap, or maybe the noise and/or time required to open the mechanism will attract a wandering monster? Either way, the player should understand that when they are asked to roll the dice, consequences await.
Having an interim element, like the ability-score mechanic that Mr. Cook outlined, seems to be an elegant solution. Success can be determined based on game-mechanical elements, but in a narrative manner. The burly warrior bursts open the door. The agile rogue deftly disarms the trap. The canny wizard deciphers the script and decodes the hidden location of a vast treasure. Each specialist is given an opportunity in the narrative spotlight. An opportunity that can be determined by player choices, and GM recognition of those choices. But, in the spirit of the game, greater challenges may offer greater risks and rewards.
As always, I’d love to hear your thoughts on the matter. Do you play with a system that handles difficulty classes in a different way? Do you prefer to roll dice to resolve the question of success or failure, or does a narrative hand-wave satisfy you in most cases?
