TOGAF
An enterprise architecture framework whose central element is the ADM, an iterative cycle from vision through business, data, application and technology architecture to implementation governance.
Its genuine contributions are a shared vocabulary, a systematic checklist of concerns that stops things being forgotten, and a repeatable structure for organisations that had none.
Its genuine risk is that the framework becomes the work. TOGAF applied literally generates a very large volume of documentation, and the artefact count is easy to mistake for progress. The framework itself says to tailor it; that instruction is the most-skipped page.
The pragmatic position: use the ADM phases as a checklist of what to think about, use the vocabulary so people mean the same things, and produce only the artefacts someone will read. Framework knowledge is not a substitute for architectural reasoning, and interviewers who ask about TOGAF are usually probing whether you know that.
