Landscape Management Process - the Big Picture
Your IT landscape consists of all entities needed to run your business. Depending on the deployment model, these are systems or tenants, servers, software products, and so on.
To keep your business running and continuously improve your processes, both servers/tenants and software are changing constantly.
We can speak of three states of IT landscapes:
- Currently used version - here, ideally, a project is running where the landscape is analyzed to provide input to change planning.
- Next version of the landscape, which is in the phase of detailed planning followed by the implementation on the system level.
Often, it will introduce "natural" changes, such as the next Support Package or enhancement package. - Future vision of the landscape to implement your strategy for the long-term planning often with more fundamental change, such as the deployment models used.
Here, specifically, exploring fundamentally new options and getting recommendations on the implementation on the landscape level is key.
The landscape management process helps you, run and evolve your IT landscape providing:
- Information on IT landscape's status quo as a basis for both landscape operation and change planning of SAP centric solutions
- Ways to change your landscape comprise installations, updates, upgrades, and conversion to SAP S/4HANA and SAP BW/4HANA
- Information required to integrate software you subscribed to
The following figure shows the landscape evolution and its phases:

In the picture, you see a landscape evolving from an pure on-premise to a hybrid landscape including cloud systems. The question where the landscape's layers are running, and who is responsible for which layers, is described in Deployment Models and SAP Offerings - On-Premise, Cloud, and Hybrid.
The steps to move from one state of the landscape to the next are based on the status quo to find the required changes to reach the next level. Having reached it, the cycle starts again. These iterations, are, of course, not clearly separated: Running in cycles, in the next step, the "new landscape" being planned becomes the one you use, and the next level gets into the details planning phase.
The steps shown for one cycle of planning and implementing changes are performed by different people in a company, fulfilling different roles. In this document, you'll find the roles involved and a list of key components and tools they need for their tasks.
