Internally at MS we've been talking about how to define and assess an organisation's "user experience capability". This is important because different organisations have different levels of sophistication when it comes to defining, creating and assessing user experience, and when I am talking to organisations I need to be able to assess 'where they are at' and what their next steps are in terms of developing their user experience skills and capacity. There's nothing to be gained by overwhelming an organisation with talk of commercial ethnography when they are still deciding whether "useability" contains an "e".
So we've been discussing a number of attributes that identify "basic", "standard", "advanced" and "dynamic" organisations wrt UX.
To my mind, one simple indicator is "who does the user interface design around here?"
This is what you typically see from my experience (this is biased more towards software development projects, rather than web projects, which would be slightly different - maybe a future post):
Software testers and technical writers often get involved too at the "standard" level. Note that my definition of "basic" is not meant to imply developers CAN'T do user interface design. With the right skills and support they certainly can (and have to). These are just my 'indicators' of UX maturity.
Your mileage may vary - what is your experience?
For other definitions, see also the "Usability Maturity Model". (More info: "Beyond usability testing: user-centred design and organisational maturity", "Usability Maturity Model". Does anyone have any experience applying this (aging?) model?
Also, here's Jakob Neilsen's take: Corporate Usability Maturity.
