When Domenicali took the helms of the team they had a very good organisation and working morale, it was bound to carry the team for a while but not anymore. The rules stayed quite the same for a long time since Brawn left the team so it's not a surprise they stayed on top for a while. Now there are new rules and new technology. The real weaknesses of an organisation are more apparent when there are big changes in rules. A good example of that is Prost/Ligier team of late 90's, they got a Brawn designed chassis in 1995 and were quite competitive for a number of years, modifying the car each year, but in 1998 there were major changes to the rules and they were absolutely nowhere and went bust.
