I know what you mean. A lot of times we might have all the parts right, but the overall picture is a bit unbalanced so to speak.
For example, in a shihonage sometimes the nage has successfully grasped the attacking hand/wrist and is moving forward with it, but instead of having that wrist in front of his center, he has it off to the side and loses control. Or when he pivots to do the shihonage pin/throw and circles uke's arm over his head, the grasped wrist is not overhead but a bit behind nage's head and uke can pull out.
Chuck Clark's description of taking control of "center" in the irimi thread is probably a good general preventative for such moments!
