your idea is quite interesting as I also think people often don´t really know what to ask for.
I just do think that that may be not enough because even if people know what to ask for you still to adapt to companies processes in some way.
People need to know what is the idea, what are the opportunities and required skills for UX Engineers, Researchers, Designers, Architects, …
You can´t work isolated but need to connect with existing people and structures.
So if you have the feeling that people don´t know really what they want it is a sign that you need to do a lot of basic work/training for getting people to understand
what is the value of working with you as an UX Expert, required tools or skills. I think it´s also our job to train and to convince people in a company about the value is UX, what tools or skills would help the company to reach goals in time. Who else than you as an UX Expert can train companies to make the best decision for them?
Managers, Developers, Project Managers have their own ideas of what is UX and how it could be integrated into the company.
The best requirements you´ll find in the UX world are there where UX people have already gained trust and respect to set requirements themselves.
A webpage/tool which tells you that
Tools: Balsamiq, Axure, Adobe Suite, Omnigraffle, UXPin, Justinmind, …
Skills: Research, Prototyping, HTML/CSS,
Focus Areas: Interface Design, Visual Design, Information Architecture, Content Strategy,
is in my opinion not enough to make the right decision for the integration of UX.
Our field is so dynamic, so complex, that it´s dificult to find a generic way that fit´s all companies.
UX Strategy decisions are best taken by UX people having knowlegde about company culture.
