Modeling Best Practices

Modeling major IT systems

Modeling complex IT systems can be challenging. We provide examples that can serve as a starting point and help accelerate the process of adding your major IT systems in LeanIX. Additionally, you will get an overview of how to model Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS), and Infrastructure-as-a-Service (IaaS) models in LeanIX.

You will find our modeling best practices for major IT systems such as SAP, Microsoft, Google, Salesforce, and AWS.

Please note that your own models may differ from our best practice examples. This could be due to industry-specific Business Capabilities and the required degree of granularity in Technology Stacks.

Import templates

We offer import templates for modeling the major IT systems mentioned above. You will always find them on the information box, such as this one:

Information boxes like this one will provide a link to the import template underneath each model.

In order to successfully use the templates, below are some helpful tips:

  • Download the .zip archive to your computer and save it somewhere where you will easily find it again
  • Make sure to import the Excel files in the correct order, as indicated by the numbers in the first part of the file names
  • After you have finished importing the files, you can start to recreate the best practice model in the Diagrams section of LeanIX
