Software maintenance types-a fresh view

Compatible with the recently proposed ontology of software maintenance, the paper proposes a fresh view of the types of software maintenance.

The classification includes taking into account evidence of: (1) changes in the character and use of the documentation, (2) changes in the properties of the software and (3) changes in the functionality of the software. The paper provides a hierarchic summary guide to the proposed fresh view of the types of software maintenance
