The issue of manual modeling in Enterprise Architecture
It is common thought to consider that Enterprise Architecture involves the manual modeling of the various sub-architectures, namely through the use of modeling tools. Such a scenario is somehow scary because it means any change or development in the manually created model will require a manual effort for changing that model.
However, manual modeling is only suitable on the first stages, when a design is created from scratch. In fact, modeling existing artefacts in an organization can be done automatically based on text information collected from different sources of information within the organization.
Even if those information sources are not updated, which happens quite often, the procedure should be update those sources and then generate models, instead of taking a modeling tool and start creating models manually. The immediate outcome might be faster, but on a medium and long term, manual modeling is an untenable situation for organizations.
Thus, Enterprise Architecture tools must have the ability to generate graphic models from information imported from different sources of information within the organization, such as, excel sheets, CMDB, service catalogues, applications, processes, etc.
