Capabilities provide a structured and stable business-centric view of what an organization does. By enabling the organization’s architecture of what it is able to do, as modular functional building blocks, capability has become a standard design element of enterprise architecture frameworks such as TOGAF, Archimate, OMG Business Architecture, and many others. Despite clear modularity and purpose of the capability notion, for many companies becoming capability-aware and being able to continuously and efficiently manage a large portfolio of capabilities is a very tedious task. To address this challenge, this study sets a foundation to leverage capability management by the means of a capability middleware broker and LLM support. The envisioned theoretical solution is exemplified by a real business case from the HE domain.
