UX under Engineering
Question: "The Blackblot organizational chart shows UX under Engineering. Isn't UX, at least partially, owned by product management?"
User Experience (UX) is an occupational domain that is broadly responsible to shape the sensory, behavioral, and emotional aspects of a user's interaction with the product.
At a colloquial level, UX is tasked with providing a guide to building the product's Externals (aka "Dashboard") while Development is tasked with providing a guide to building the product's Internals (aka "Engine").
Those Externals and Internals are joined to create a functional, usable and esthetic product.
In any case, according to second foundation rule of the Blackblot PMTK Methodology™, UX resides in the solution space and therefore is in no way part of product management.
For more information, please see the The User eXperience (UX) Domain chapter, pages 159-164, in the Blackblot PMTK Book: Second Edition.
