Once you have a model and some rough data sources you can iterate and attempt
precision that is useable. I agree that the precision isn't there yet (my
scientific way of saying "smoke and mirrors") but I won't rule out that this
can get good enough to be used for decision making.
There are decisions being made on app sec spending but it is ad hoc right now.
Organizations are spending money of app sec and they are also spending money on
cleaning up breaches. They do think about reducing breach costs to the
organization. This model can help them do that.

Security debt seems to me a very useful concept. Thanks, Chris.
As I pointed out in my blog post
(http://www.artima.com/weblogs/viewpost.jsp?thread=320875), I do not believe in
quantitative models though. Clearly, it is interesting to try to nail the
factors that contribute to the cost and to establish whether it is cheaper to
pay back or service the debt, but to put numbers on these costs is smoke and
mirrors imho.
