Developing an EA
Testing and Evaluation
Author: Saurabh Mittal, PhD
An EA is a complex endeavor and involves people, processes, artifacts, technologies and data-exchanges. A lot of effort goes into EA design and requirements development. Consequently, requirement satisfaction is an integral part of EA engineering. Testing and evaluation (T&E) of any system or an enterprise architecture for that matter, begins with requirements. It is the backdrop on which the testing is performed and the architecture is evaluated.
T&E needs to be applied to each aspect of the EA, for example, governance, business processes, data and information artifacts, technology, software, etc. Methodologies are available that can do T&E for a particular aspect, however, an end-to-end T&E needs new approaches.
Another similar concept is verification and validation (V&V). While V&V relate more closely to models and software, T&E relates to actual systems and architectures. It is hard to perform V&V with Commercial-off-the-shelf (COTS) and Government-off-the-shelf (GOTS) when they become components in larger systems or architectures, due to the black-box nature of the various components. Consequently, T&E is performed to ensure that the requirements are satisfied when the conceptual EA goes into design and implementation phase.
Various T&E approaches for EA, not limited to: model-based testing, automated test-case generation, requirements traceability, analytic architectures, test-suite automation and dashboards development, need to defined for effective EA analytics.
