The present invention is a method for creating common functionality software units (555) suitable for controlling a telecommunications switch. The common functionality software units (555) are created by performing a domain analysis (542) on all existing telecommunication switches (502) which results in the identification of common concepts, terminology, behavior, and functionality for all possible combinations of Bearer Service Handlers (BSHs) and types of hardware (HW) for the switches. The common behavior and functionality is implemented in a Universal Common Software Template (UCST) (548), an associated Parameter Definition Document (PDD) (544), and an associated Collection of Data Type Definitions (CADTD) (546). The UCST is compiled and tested with a subset of the CADTD. After the UCST is compiled and tested, a plurality of common software function units (CSs) for the different combinations of BSH and HW may be created from the UCST and the CADTD.
