  In this paper, we propose a method for aligning models with their realization
through the application of model-based systems engineering. Our approach is
divided into three steps. (1) Firstly, we leverage domain expertise and the
Unified Architecture Framework to establish a reference model that
fundamentally describes some domain. (2) Subsequently, we instantiate the
reference model as specific models tailored to different scenarios within the
domain. (3) Finally, we incorporate corresponding run logic directly into both
the reference model and the specific models. In total, we thus provide a
practical means to ensure that every implementation result is justified by
business demand. We demonstrate our approach using the example of maritime
object detection as a specific application (specific model / implementation
element) of automatic target recognition as a service reoccurring in various
forms (reference model element). Our approach facilitates a more seamless
integration of models and implementation, fostering enhanced Business-IT
alignment.
