In their first two matches, the Scots have lost heavily to Ireland and France but McGeechan denied his game plans are in need of a radical change and claimed aspects of the defeat in France last week had been pleasing.
He said: "We won't have to change tactics much at all. We probably broke the French defence more than England did but what we're not doing is finishing off our moves.
"There are some good things in the games but cumulatively they haven't resulted in scoring and that's something that we're all disappointed with.
"But France are a very good side and played very well and there will be a few countries who will have problems in Paris.
"And although the score was disappointing, there were a lot of players working very hard in that game.
"We have a group of players playing well and we're looking at the positives in the way those players are performing.
"So it's not about throwing those things away, it's about amending and adding to them. I think we've got a good way of playing which has underpinned everything we've been trying to do for a number of seasons.
"But we're trying to get the balance and the performances right and want to create the sort of consistency that we were starting to achieve during the Autumn Tests and even before them.
"The next challenge for us is Wales and we'll be putting out the best team to beat them. I saw them against England and I thought they played well."
