The Eagles were particularly busy over the summer, with 16 additions made to a squad which secured promotion into the Premier League via the play-offs.
Former boss Ian Holloway admitted on his way out of the club that he had made too many alterations - with early season struggles a direct result of an influx of fresh faces.
Palace are eager to avoid a similar scenario in January and new transfer guru Moody will look to ensure that the right issues are addressed, rather than more wholesale changes made.
"I don't think there will be 15 or 16 players coming in during January - that would have a destabilising effect," he told the South London Press.
"It is about fine-tuning, identifying the two or three players you need to try and upgrade.
"All managers have different fetishes of players. The first thing I say is to give me five measuring sticks - what your ideal goalkeeper looks like, what your ideal left-back looks like and so on.
"If a manager only wants a goalkeeper that is at least 6ft 4ins tall then there is no point looking at one that is 5ft 10ins, no matter how good he is, because he doesn't fit the model."
Moody, drafted into Selhurst Park following his departure from top flight rivals Cardiff City, has also revealed that he will be looking to explore one market he knows particularly well - the French one.
He added: "I speak the language and players over there represent good value.
"With the exception of Paris St Germain and Monaco they don't pay huge money. Culturally and linguistically they are popular to UK clubs. They produce a disproportionate amount of good players.
"A lot is dictated by the philosophy of a club. I always ask what is the perception? I've always known Palace as having razor-sharp wide guys and two guys holding. An athletic and quick team.
"Apart from the very top teams in England, you don't have the resource to scout every country. I'd rather concentrate on two or three countries that have a history of producing in the UK rather than spending one week in Poland, one week in Croatia and one week in Belarus. You never get a depth of knowledge.
"If you see a good left-back in Croatia and Portugal it is almost impossible to judge which is best for us. I'd rather watch every left-back in France, Holland and Belgium."
