Applications are interconnected through numerous point-to-point integrations, making the landscape brittle, hard to understand, and difficult to change. Key characteristics of the current situation include: An outdated and fragmented IT and data landscape, with some business critical systems build on legacy technologies. Many applications are directly coupled to each other and connected through undocumented or poorly governed integrations. The IT organization is lean , with no internal architecture capacity.
