Re: [ba-ohs-talk] IBIS question
Jeff, (01)
I appreciate your advice on how to better use IBIS-as-is for my
example problem. In fact, I probably
should have thought through my example a bit more before posting it
to this community because the example most certainly has its flaws as
I outlined it... on the other hand, I'm still not sure even with what
I learned in the various responses that IBIS-as-is can represent what
I (speaking only for myself) would like to represent. (02)

I agree, that's why we put it into our product. (04)

I agree with that, too, but what I'm missing is a better way of
documenting the relative merits of the reasons in favor or against a
decision. In other words, why I made a decision in favor of Idea 1,
as opposed to Idea 2 given that both had the same number of pros and
the same number of cons, for example. (Let's just assume for a moment
that I'm the only person in the picture, it's a single person
decision rather than a group decision). (06)
What I'd like to capture and document for reference purposes is
something like "I think that the cons for Idea 1 are small compared
to the 2nd con for Idea 2, and the pros of Idea 1 beat all pros of
Idea 2." (07)
So half a year later I, or whoever else after I was hit by the truck,
can go back and say "ah, he thought Pro 12 had so many advantages
that he chose to live with Con 34 -- well, that's not true any more
because of changing conditions of some sort, and this was the crucial
consideration that caused the decision to go in favor of Idea 1 as
opposed to Idea 2. That probably means we have to reconsider ..." (08)
Maybe my usage scenario for IBIS is a little different than
originally intended -- not for facilitating group decision making,
but for decision documentation. (09)
Do I make sense? (010)
