A hierarchical object is exported from a first electronic system to a second electronic system, where the hierarchical object is modifiable at each of the first and second electronic systems, and where a baseline version of the hierarchical object is created. A first version of the hierarchical object at the first electronic system is compared against the baseline version, to form a first data structure identifying any changes between the first version of the hierarchical object and the baseline version. A second data structure is received identifying changes between a second version of the hierarchical object at the second electronic system and the baseline version. A visualization based on the first and second data structures is provided.
