Impact analysis and adoption planning based on global where-used lists

摘要

Local dependency metadata can be collected from local metadata repositories of a plurality of development systems in a layered development system landscape, and a global where-used list that includes intra-layer and inter-layer dependencies between development entities in a layered development system landscape can be created, for example by aggregating the collected local dependency data. A usage metric quantifying how frequently each development entity is depended upon by other development entities in the layered development system landscape can be assigned to each development entity in the layered development system landscape. A measure of a relative effect of a change to one of the development entities on other development entities in the layered development system landscape can be promoted.
