7.4.2 Use Case Approach to Business Metadata Systems Design
As described in the previous section, the IT department of EUB decided to revise their
current approach to business metadata. Therefore, we applied our proposed use case
classification following the presented VORD approach presented above (see Abb. 13).
As a first step, EUB prioritized the use cases in order to focus the analysis on the most
relevant ones (section 7.4.2.1). We then documented in an exemplary fashion the requirements
for the top priority use case in a collaborative workshop (section 7.4.2.2).
7.4.2.1 Use Case Prioritization
The EUB chose two employees of business and two of IT to identify the use cases with
the biggest relevance for EUB. All of them were asked to study a comprehensive set of
use case assessment templates and to provide their personal perspectives on the business
potential and associated costs/burdens of their implementation per use case.

Abb. 15: EUB’s prioritization of use cases for business metadata
Each template included a high level description of the use case, typical challenges, and
likely business metadata needs to address these challenges. Subsequently, the employees
were asked to name their top three to five use cases and explain the underlying
rationales. Abb. 15 illustrates the collective results. From the given use cases, the EUB
employees identified “data development” as the most relevant for EUB and, therefore,
the prime candidate for exemplary viewpoint documentation.
