IT1913 Enterprise Architecture Modeling Processes are also used as a starting point in visualizing a model. Central Model is Modeling as a Transformation Process an example of a way to visualize a model. Knowledge Representation – This depicts an enterprise architecture Using the model – This activity uses the model representation to model in a specific manner based on the agreed perception of the communicate with the stakeholders and evaluate whether the model and individuals involved in the process. the visualization achieved the intended outcome. The following are the Knowledge Goals – These are the goals under the modeling process of typical steps in using visual representation: an enterprise architecture. o Validation – This involves checking whether the key stakeholders Knowledge State – This involves the condition and commitment of agree that the viewpoints in the model are correct representations stakeholders on enterprise architecture. of the actual and intended situation. Knowledge Transformation – This is the situation where knowledge o Obtaining Commitment – After reaching an agreement during passes through the modeling process while considering goals and validation, the key stakeholders must commit that they fully guidelines. understand the potential impacts of implementing the model. Central Representations – These are the primary and essential models o Informing – This involves the dissemination of information to all that are used in the transformation of knowledge. the stakeholders.

Different Modeling Activities Refinement – Refine an element in a model. Other than introducing new Establishing the purpose, scope, and focus – It is a goal-driven activity elements, refining can be done by adding specific details to existing wherein architects determine all possible stakeholders and the different elements. The following are the two (2) forms of refining an element: purposes of the model in relation to the stakeholders. This is considered o Classify the newly introduced candidate element based on the as a starting point in establishing a model. concepts used in the model.

Additional information can be Abstraction – Abstract from a concept or relation. The concept of acquired using interviews or discussions with stakeholders.

This is the process of finding a suitable alternative for an element. Documentation is required in order to keep track of the existing relationship between models or contexts. The following are some of the possible process-related translation (Lankhorst, et al., 2017): o Creating or replacing an element so it matches the meaning of a concept from another language or context. o Linking an element to an element on another model or modeling language. o Linking an element to an intermediary language when a model needs to be translated to more than one language or context. o Specifying rules to empower standardized and coherent translation between a context and a language. Documentation – Document modeling actions. This action involves the administration and documentation of all or some modeling actions, such as refinement and abstraction. The following are some of the reasons for documenting modeling actions: o To be able to backtrack the previous state of a model. o To revisit rejected alternatives. o To record modeling logical basis related to traceability, accountability, etc. of a modeling process. o To add conceptual meta-data, such as date, location, name of the person who performed the activity, and the specific model elements that were affected.
