Utilitarian criteria: This is concerned with the degree in which taxonomy is helpful and efficient of the research that is in general this criterion proposes that the valuable taxonomies assist communication by normalizing the terminology in a field that were used to work on applied issues, which need few start-up charges and have a big user base.
