DX Core 4
A framework from DX that groups DORA, SPACE, and developer experience into speed, effectiveness, quality, and business impact. DX publishes it. We have not marked other tools as implementing it.
Why it matters to an engineering manager
It is useful as a conversation structure with executives. It is not a tag in this directory, because other vendors do not publish "we implement DX Core 4" in the fields we track.
Which tools measure this
This directory does not tag this term on its own. The definition above says what we would be claiming if we did.
