Sorry for not volunteering it - I'm not usually shy about such things,
but I didn't think it was quite what you were looking for. I asked
subscribers to CHI-WEB, BCS-HCI News and the
usability-list-that-shall-not-be-named (really, they'll cut my tongue
out<g>) to indicate their use of a variety of usability and UCD tools.
It was fairly informal, especially since I did not define each precisely
(so respondents were left to decide what "user analysis/profiling"
meant, but I think it did provide some useful insights: the most
important being that most folks are not using a "method" (in the
software methodology sense) as such, but rather just a collection of
techniques. Anyway, in my chapter in _Object Modeling and User Interface
Design_ (details below), I incorporate the "user-centred top-ten"
techniques into the informal UML process used by many software
developers. More recently I've done something similar for Agile (see
http://www.syntagm.co.uk/design/articles.htm and look at the recent
papers section at the top).

Here are the survey results. I have some spare copies of the book
available through the Amazon.co.uk book (my copies are very similar to
Amazon's<g>, but cheaper.

Many thanks to those who responded to the survey. I received a total of
102
responses from the three lists (CHI-WEB, the 
usability-list-that-shall-not-be-named, and the British HCI Group). 9
responses were excluded from the figures below due to confusion over the
instructions.

Responses were fairly international, with respondents based in the US
making
up just over 60% of the total. (Since many email addresses were .com or
.net, signatures, web sites and just plain old asking were used to
determine
the location of respondents.)

Responses by country
us      61.3%
uk      12.9%
nl      3.2%
se      3.2%
be      2.2%
fr      2.2%
il      2.2%
au      2.2%
ca      2.2%
de      2.2%
fi      2.2%
ie      1.1%
ir      1.1%
it      1.1%
mx      1.1%

The majority of respondents were usability practitioners:

usability practitioner         64.5%
information architect           7.5%
developer                       6.5%
developer + usability/HCI       6.5%
HCI researcher                  4.3%
project manager                 3.2%
technical writer                2.2%
software testing/QA             2.2%
design director                 2.2%
technology manager              1.1%

Not surprisingly, many were involved either in a mixture of web and
"traditional" software development or web development exclusively:

web only                        45.2%
mixed web + desktop             33.3%
desktop only                    11.8%
other                            5.4% (speech, medical x-ray,
electronic lab equipment, air traffic control)
consumer electronics             2.2%
mobile comms                     1.1%
multimedia                       1.1%

Most respondents spent almost all of their time applying user-centered
methods:

All or most                     68.8%
less than half                  19.4%
occasionally                    11.8%

Finally, here is the list of techniques that respondents used (excluding
any
used by only 1 person):

informal usability testing                              93.5%
