The Chelsea captain has been handed a four-match ban and fined £220,000 by the FA after an independent regulatory commission found him guilty of using racist language towards Anton Ferdinand.
The original incident occurred in a Premier League game at QPR on October 23 last year, meaning it took over 11 months for the case to reach its conclusion.
Scudamore told the Daily Telegraph: "It is very difficult, but my concern is the length of time that this takes because we have been sitting here, unable to move on and unable to get clarity. We have to work out a way of doing these things earlier."
There is also the possibility of an appeal from Terry to come once he is in receipt of the written judgment.
Terry was found not guilty at Westminster Magistrates' Court in July of a racially-aggravated public order offence in connection with the same incident.
The FA was not prepared to begin its own disciplinary process until the court dealt with the case, but Scudamore does not see why that was a necessary step.
He said: "If the argument is that these (charges) are completely separate, irrespective of what the courts decide, if football's test is different, why can't we decide (the outcome) if it is a completely different test?
"I don't quite know why one has to wait for the other if the tests are completely different.
"It would have been much better for everybody, whether the outcome is positive or negative, if it was done quickly."
PFA chief Gordon Taylor believes the length of time taken to deal with the Terry case has caused divisions which may never be healed.
Taylor said the delay had caused the issue to "fester" within football.
Taylor said: "Almost 12 months on and the John Terry case was still not heard by the FA until the day after Luis Suarez shook hands with Patrice Evra at Anfield. Such a delay has allowed the matter to fester and cause divisions in the football family which will take a long time to heal - if they ever do."
He added: "We have to move on now and move on together and continue our focus to eradicate racism from the game and society.
"There should be new educational processes for all players - young and old, and for managers and directors.
"There should be equitable recruitment processes, and a fast-track disciplinary process that does not allow for delays or holding off at the request of the Crown Prosecution Service."
The FA had delayed their own disciplinary hearing until after the magistrates court case - where Terry was acquitted - at the request of the CPS.
