The British like decisions to be made in a team environment and a good manager will work hard to ensure 'buy-in' from his or her team. The team environment aspires to being friendly and companionable with individuals within the team being seen to be supportive and helpful of each other.
If, however, something goes wrong, it is not uncommon for the team to look for an individual within the team to blame. ('Blame culture' is something that seems to permeate working life and many organisations work hard to try to change this type of mentality.)
Team members often bring with them into the team a certain level of specialisation, but are expected to take a generalist view of the project and their role within the project team. Being seen as a 'good all-rounder' is definitely positive.
