My Different Slant article on people-centric organisation design in HR Magazine is now online.
The article suggests modern organisation design will increasingly involve a mix of traditional functions, horizontal (process, project, product, agile) teams, communities and networks, as well as melds of these.
I've outlined these models in a bit more depth in Linkedin. You may like to check out those posts there as well:
