Here I want to add my understanding of this model:

"Competency" is a concept put forward by Harvard Professor david McLelland in 1973, which can distinguish people's working ability. It is a measurable, multidimensional and clearly differentiated standard. At present, major domestic enterprises have begun to use competency model as an evaluation standard in employee management.

Competency model is to use behavior to represent the professional core skills needed by employees with excellent work ability; Determine the key abilities and business proficiency required to complete the work through layered concrete behavior expression. These behaviors and abilities are linked to performance and can be measured and observed. Competency model is the synthesis of seven abilities: execution, innovation, learning, team management, judgment and decision-making, coordination and risk awareness.
