Villa are seeking a replacement for Gerard Houllier.
Taylor told BBC Sport: "It just doesn't appear to have been thought through and for the first time the ownership of the club is coming under severe criticism.
"When Gerard became ill it must have occurred to them that he may not come back, even if the signs were that he may have returned.
"This is not being disrespectful to Gerard in any way, but once he became unwell then you have to immediately start exploring what you might do if he does not come back.
"It doesn't appear to me and many others that this has been done. They seem to be going from name to name.
"Villa don't seem to have grasped that nettle at all. It is disappointing. I still live in the area and have a special feeling for them as you always do about clubs you have managed, but I have been surprised and disappointed at their handling of this."
