Thanks for the references dude - but I wouldn’t have asked for a summary of criteria if I had the time to lookup and read the entire articles.
In any case, I’ll try to respond to your questions in the next couple of days.
That’s sort of what I said too… there are just too many fuzzy regions - hence the idea of looking at people’s careers as more of a continuum rather than a matrix. Also, this is more so today when we live along the lines of managing Protean Careers rather than working within well defined job roles.
