no methord of management is correct. an application when applied for an automobile manager is not the same for that of a chemical factory manager. every successful managers have their own unique ways of interpreting things and if their action and decision becomes a success every one calls him an efficient manager and if it does't then the manager interepreted it wrong. no professor in management theory can define or say a particular management style would be very effective for a particualt type of organisation.
good managers need to understand the broad aspects of taking a decision which includes understanding cultures and geography.
so i would say develop your own styles of managing people and you become more effecive.
