What are the obstacles to the delegation of decision-making power and action?

Thanks for invitation,

The main obstacles of delegation process are:

1- The lake of tasks' definition that are delegated.  

2- Improper choice to the right caliber.

3- Applying Micro- Management style by the delegator himself.

4- Failing in following up and control from the delegator's side.

Delegation is a positive strategy, if done with clear objectives and boundaries.

Egos, Departmental authority issues, Office politics. 

Lack of leadership and managerial capabilities and  failure to understand the bigger picture of delegation.

Thanks

No given authorities, represents as a main obstacle which will lead to similar result and some times nepotism give the same results.
