After losing out at Shrewsbury's Greenhous Meadow thanks to a 94th minute winner from Shrews debutant Shaun Miller, Parkinson's men entertain Walsall at the Coral Windows Stadium this Tuesday.
The Walsall game is City's final Tuesday night home game of the season and will leave them with only three games at Valley Parade left to play thereafter.
Having watched the Shrewsbury game once again on DVD on Sunday morning, Parkinson identified a number of aspects he wasn't happy with and he wants the Bantams to put things right against Walsall.
Parkinson said: "Losing with virtually the last kick of the game - it really is the worst way to lose a match.
"The lads were really hurting after the game because of it.
"The good thing for us, however, is that we have this game coming up on Tuesday and it gives us a chance to respond.
"All of the things that weren't quite right at Shrewsbury, we now have the opportunity to put right on Tuesday night.
"We didn't dominate the game on Saturday as much as we should have done, especially in the second half when the elements were in our favour, and we have to analyse why that was the case and how we can put that right on Tuesday.
"The way we managed the final stages of the match at Shrewsbury was poor - a point probably wouldn't have been the worst result - but it has gone now. All we can concentrate on now is approaching this Walsall game in a really positive fashion."
Dean Smith's Walsall will come to Valley Parade this Tuesday with a reputation for precise passing football.
With that in mind, Parkinson has let fans know that Tuesday's game could be a similar sort of match to the one City had last month with Milton Keynes Dons - another side renowned for their structured build-up play.
Parkinson added: "We know how Walsall like to play and we will have to be solid and organised against them.
"It will be a similar situation to the one we faced when we welcomed MK Dons to Valley Parade last month.
"When you come up against a side with that extra player in the middle of midfield there are going to be times when they have possession of the ball.
"We have to understand that and not get too frustrated.
"We have to look at ways at not only dealing with their play, but exploiting Walsall in other areas."
