Meaning – Administrivia corresponds to the details that must be taken care of, and the tasks that must be completed in order to run an organisation.
The other way to look at the word administrivia, is any kind of paperwork that hinders the accomplishment of one’s objectives or goals.
Obviously, the reason that administrivia is considered to be a hinder to development, is because these tasks tend to be cumbersome or tiresome, and some people tend to spend a lot of time taking care of this paperwork and by the time this is done, they lose interest in completing the tasks at hand.
In order to avoid this monotony, managers have started to delegate the moe cumbersome tasks to their assistants, while they themselves, focus on the policy making.
Example of usage – “The Manager sets the policy and leaves the administrivia to his assistant”.
