From taxonomy I to taxonomy II

Taxonomic development in nursing, although still in its infancy, is progressing. Taxonomy development has moved beyond subjective placement of diagnoses into categories based on an "expert" opinion alone. The taxonomy of nursing diagnoses is entering a new era whereby the assumptions and classification rules for Taxonomy I--Revised are being investigated. Alternative taxonomic structures require careful scrutiny and comparison to establish whether one structure will meet the needs of the profession or whether multiple structures of nursing diagnoses relative to outcomes are required. As members within the discipline become more sophisticated in approaches to taxonomic development, methods of handling taxonomic problems, such as varying levels of abstraction and taxonomic affinity, will be discerned.
