The sentence I put in red is the reason I initially devised 
Willingness-Determination and Willingness-Factors and put them into 
the Communication as Joint Action diagram because I thought that 
willingness to communicate is (or can be) different from willingness 
to actually perform a service. Even if we don't indulge in processes, 
willingness to usually communicate precedes all mutually successful 
interactions leading to successful actions, although any number of 
actions can be initiated without communication--they just won't be 
successful from the SOA Ecosystem viewpoint .

(The guy that outfitted a bulldozer like a tank and went berserk in 
some small town in the midwest a couple-few  years ago certainly 
committed an action that he might even have considered successful but 
which sure didn't make his local economy-ecosystem a happy, smoothly 
functioning place).

Cheers,
Rex
