## Abstract

A method and associated system for managing rules that synchronize operations of a source system and a target system. A set of linked worksheets is generated as a function of the internal logic of the synchronization rules and of worksheets that represent data models of the source and target systems. These generated worksheets describe and relate data elements of the data models, extrinsic data that is stored externally to the source and target systems, and logical procedures performed by the synchronization rules. When the source data model, the target data model, or a logical procedure is revised, the linked worksheets are updated in response to the revision and these updates automatically propagate across the synchronization rules and across other components of the source system, the target system, and the synchronization mechanism.
