I agree people are more effective if they are triggered by their own interest (intrinsically motivated).
How vere the question is, these people must have all conduicive
environments that would enable them to start their own self
motivational motive
This environment is purely external that may be enhanced by any
one -managers, owners.. Therfore, although not as general
deduction, the role of the interface between the the inherent
behavior and the motivational work is the manager..
Another point is from social practices, we always observe the following
– Many employees are always interested to here appreciation ,
(recognition from the managers . This appreciation may require to
be supported by some material incentives to be long standing.
Otherwise recognition is not a short term motivation instrument
ofcourse without forgetting contineous changes to be made on
type and level of motivational instruments
– Children are motivated by appreciation of their elders
– Students are motivated to work when they get appreciation from
their teachers
Therfore it appears that need for appreciation is not onl;y inherent but also shall be triggred by some external force. In this case I dont see any reason to completely abandon the roles of the managers , replacing it by giving freedom to workers taht would enhance them to be self motivated-
More over this, how about the control that would go with accountability

I AM NOT CRITICIZING BUT WANT TO LEARN
