Hi Fil and Klaus,
Why not use classical variety analysis a la Ashby to assess relative
complexity and wickedness? It works regardless of discipline or problem
type.
Difference between system variety and available control variety (i.e. what
the designer knows and can manage) is the amount of guessing or designerly
skill being used.
Cheers,
Terry

Subject: engineering design v graphical design - comment to Klaus.
Klaus, just a point of clarification:

Yes, there are many simple "engineering problems", but I think we need to
focus here on /engineering design/ problems. And I don't think there are
any simple /engineering design/ problems.
(Please recall that I and most of my engineering colleagues would /not/
consider things like configuring a gear box, no matter how complex it might
be, as design problems.)
Cheers.
