Hi Chakri,
:) 'Competencies' are defined in domain specific, i.e. a particular set of qualities may act to be effective in a particular situation.
You may take it in the following form :
Effectiveness = function of (Perception, Attitude, Domain Knowledge, Learning, Organizational parameters .. )
In which, Organizational psychologists are concerned with attributing the 'human' factor of 'potentially effective' skills that are required to complete the job effectively. If you tell me in which area of training you are working presently, probably I may try to be of some help. Lots of inventories are available, however each work in a different set of circumstances.
Regards.
