The experienced Smith, capped 52 times, refused to blame anyone but himself for his part in the Welsh defeat but vowed to make amends against the world champions.
He said: "I was disappointed by the way I played.
"You look at your performance week to week and if you're not playing well then you've got to do something about it and I've got to do something about it.
"I'm speaking for myself not the other senior guys. If you fail to meet your standards then you've got to recognise that and improve and I would put myself in that category.
"We had systems in place but to be honest when the pressure came on we didn't play them.
"And it's fine for someone winning their first cap, you can say to them that they're new and getting used to things but I've been around a while and I can't really hide behind that.
"We had a bit of a rude awakening last week and we found that the systems were not just going to happen by themselves.
"You've got to work hard to put a game plan into action. You need all the forwards doing the same thing and everyone reading from the same song sheet."
The Scots upset the odds at Murrayfield in 2000, beating England 19-13 when the visitors were strong favourites.
But Smith believes Sir Clive Woodward's class of 2004 are too focused and determined to be caught off guard again.
He said: "We definitely won't catch England as complacent as we did in 2000.
"They've shown that they are ruthless in selection and players aren't allowed to settle down into a comfort zone because there's always another good player snapping at their heels."
