teams help have/make everyone accountable for the project success
success need be well defined
teams break down traditional vertical hierarchy
but individual accountability still exists, in a different order
we are all either responsible for something,
or responsible to help someone else with something
both are very important in teams
it is very important to know the difference
...it is often hard for managers to be in the position where they are responsible to help someone and to let them lead; if that person is "under them" in the traditional up and down hierarchy which still exists at the same time as teamwork dynamics are introduced in the organization.
et vice versa...
