How to make an ideal employee a stimulation factor for the rest of the staff?

Thanks 

I support my colleague Obaid's answer 

By higlighting him, appreciating his/her performance loudly and by promoting him with monitory benifits. 

Management must  always be sincere with an employee eventhough he is weak in his performance he should be educated and provide best of best support to obtain innovative performance from him  . I hope no employee will cheat himself. 

Thanks for invitation,

By choosing ' The Man of the Month" competition between your staff.

Raising the morale of the employee increase the physical motivation and stimulation and sensitive sense of the employer

I too support Obaid.

Money is the best motive ..
