Managing the costs and complexity of the applications
What is an Application Architecture Landscape and why is it so important to have?
An application landscape map or applications architecture diagram is a logical functional and/or physical technical overview of all the software applications in the information systems and their interfaces and connections in an organization. An application landscape is a perfect visualization for managing the costs and complexity of your applications.
Demo: Generate Applications Architecture diagrams
In many organizations there are hundreds, and if you count all unofficial spreadsheet apps with it, thousands of applications. And everyone in the business relies on them. In the current time of fast-changing needs, lots of applications are replaced, updated, integrated, and connected.
So to keep your business going, you need to know beforehand what the impact is of changing a certain application, made visible with the landscape. Having a printed poster or digital application map available is of great value.

How to create an Application Landscape diagram?
The process:
An application landscape is often created by quickly scanning the installed base, doing interviews with users, and workshops with management. This gives a start to an overview of all the applications. Next, a process is implemented to keep the application landscape diagram overview up-to-date. The application landscape can then be used for decision-making and impact analyses of change.
The architecture:
Dragon1 EA Method proposes to create an application metamodel and take time to carefully define the types of applications and the core functionality of the applications. This allows the maximization of deduplication.

Dragon1 is the most suited software available for generating an application landscape with views based on information in a CMDB tool.
Solution for Rationalization
A solution in which often application landscape diagrams are used is Application Rationalization Deduplication.
All applications that duplicate functions are if possible phased out or switched off. The objective is to lower the complexity of the application landscape diagram and to average application cost. Read the case study Application Portfolio Management at a Bank.
