This is an opinionated proposal on how to creating an architecture. You may deviate from it at any point, but if you don't know where to start, this is a good starting point.
System Architecture and System Landscape provide different perspectives and different levels of detail of looking at an architecture. In the following process, the steps 1, 2 and - A.1 describe the creation or update of a System Landscape, while the steps 1,2 and B.1-B.7 need to be performed when creating the System Architecture.
{% hint style="info" %} For architecture-based institutional coordination, such as cross-agency data governance, interoperability oversight, and the role of digital authorities have a look at design-a-government-architecture.md. Based on the concept of Enterprise Architecture, Government Architecture provides a more high-level and complete view on all systems within a government. {% endhint %}
Consider this as two alternate paths, depending on what view on the system you are interested in.
