Subject: RE: [soa-rm-ra] My refactor of the willingness and trust diagram :)

I have to weigh in.  About a year ago I recommended a definition of
Trust as "continuous performance to commitment."  Ken, Frank, and/or
several others corrected me that this definition was of "how to build
trust", not trust.  

However, I do not give up on ideas based on my experience.  It seems to
me that trust has a couple of interesting attributes.  First, for lack
of a better term, trust is transitive.  If I trust someone judgment on a
particular topic and they trust someone else's judgment on the same
topic, then I have more of a tendency to trust the second person.  For
example, I trust my primary care doctor (body mechanic).  He recommends
that I go to a specialist for a physical problem.  I immediately have a
level of trust, since most of the time, the specialists he recommended
have been good.  However, occasionally the doctor has been uncaring or
otherwise semi-incompetent.  That is the reason I indicated "a level."

Further, there are instances, like the Enron and Madoff scandals, when
the trust level for entire industries goes south.  "Runs on banks"
demonstrate that trust is a discontinuous function.  That is, "one Oh
Shit...more than equals 1000 Atta Boys."

So from my perspective Trust has three attributes
1. it is built on continuous performance to commitment
2. it is somewhat transitive (but not entirely)
3. it is discontinuous--it's built slowly and lost instantly.

Maybe all of you came to these conclusions early, but Ken's note seemed
to indicate otherwise.

My 2 cents--while on vacation.

My problem with this is there is Evidence and that Evidence may
contribute to the assessment of Trust, Risk, both, or neither.  Your
diagram makes it look like the evidence has to be in one bin or the

In addition, Willingness does not just come from Trust but rather from
an adequate balance, as decided by the Trusting Actor, between Trust and
Risk.  Also, your Reputation is an orphan with no use other than to be
called out.
