Why is it useful to create Transition Architectures in the Application Architecture domain?
According to the SAP Enterprise Architecture Framework, which is a methodology and toolset by the German multinational software company SAP that helps enterprise architects define and implement an architecture strategy for their organizations, Transition Architectures are intermediate states between the Baseline Architecture (the current situation) and the Target Architecture (the desired future state). Transition Architectures describe how to move from one state to another in a feasible and manageable way, taking into account the constraints and dependencies of the project. Transition Architectures are useful for structuring complex application architectures that require multiple changes of existing interdependent applications and/or the rollout of new applications. Some applications/solutions depend on the existence of others, meaning that they cannot be implemented or operated without the presence or functionality of other applications/solutions. For example, a new application that relies on data from an existing application, or an existing application that needs to be integrated with a new application. By creating Transition Architectures, enterprise architects can:
Define and prioritize the sequence and timing of the changes and rollouts that are needed to achieve the Target Architecture.
Identify and mitigate the risks and issues that might arise during the transition process, such as technical, operational, or organizational challenges.
Communicate and align with the stakeholders and sponsors of the project, such as business owners, users, developers, vendors, etc.
Monitor and control the progress and performance of the project, and ensure that it meets the requirements and expectations of the project.
Transition Architectures are useful in the Application Architecture domain because they can help to structure complex application architectures that require multiple changes of existing interdependent applications and/or the rollout of new applications.
In some cases, it may be possible to make changes to existing applications independently of each other. However, in many cases, changes to one application will require changes to other applications. This is because applications often depend on each other for data or functionality.
Transition Architectures can help to identify these dependencies and to plan the changes to the applications in a way that minimizes the impact on the business. They can also help to ensure that the changes are made in a consistent and orderly fashion.
The following are some of the benefits of using Transition Architectures in the Application Architecture domain:
They can help to improve the visibility of complex application architectures.
They can help to identify dependencies between applications.
They can help to plan the changes to applications in a way that minimizes the impact on the business.
They can help to ensure that the changes are made in a consistent and orderly fashion.
Therefore, Transition Architectures can be a valuable tool for managing complex application architectures.
