Every organization has talent, which is more diverse than the roles available and assigned to an individual employee.
Every organization has a purpose to fulfil and obviously the roles are derived from that end purpose in mind and assigned top down. Though there is nothing wrong in this approach and nor does it need to change, this approach does not utilize the hidden talent of your employees, at times it could be a wrong assignment of a role; which is difficult to get rid overnight, and sometimes it is the absence of right encouragement which stops the employee from opening up.
Bigger problem though is the lack of realization, both on employers and employees part, that the talent is right there. Organizations constantly are trying to reduce the existence of this problem and many have succeeded to some extent. It is a quest to leverage what they own and pay for, pick the brains of their employees and convert that non time consuming sparks into revenue generation offering or a cost saving process.
