unsystematic
Lacking coherent organization
Unsystematic means lacking organization or method.
An unsystematic approach proceeds without a clear plan or consistent pattern: His filing system was unsystematic—papers stuffed wherever they fit.
The word often implies inefficiency or incompleteness: an unsystematic search, unsystematic data collection.
