Which type of organization expects important decisions to be made by top-level managers?
tankabanditka [31]

Answer:

In the centralized organizations which mostly includes banks, army corporations, etc because in these organisation the policies are set by the top management and the lower level management have to follow their instructions. I remember when the japanese Cheif Executive was appointed as the CEO of Sony America the whole of the workers went to strike against him because his attitude was centralised oriented organization which he was used to in Japan and in America people love to work in decentralized organisation. So basically in centralised organisation, lower management are delivered less responsibilities regarding making decisions. They are only accountable for doing the job according to the top management.
