Germans, those leading as well as those being led, prefer generally formulated, mission oriented tasks. The mission addresses more the what and less the how. Responsibility for the how lies with the implementer on the tactical level.
Americans﹣those leading as well as those being led﹣prefer specifically formulated, command oriented tasks. The command addresses both the what, and to some degree the how. Overall responsibility for the how lies on the strategic level with the team lead, but is shared to some degree with the implementer.
