How to fix "Performance Expectation Level" of employees in a Business Establishment from the Marketing point of view?

I believe the the yield expected from an employee from marketing perspective should be:

S M A R T =SPECIFIC,MEASURABLE,ACHIEVABLE,RELEVANT,TIME BOUND.

TARGETS VS ACHIEVEMENTS ==== ATTITUDE ==== PARTICIPATION IN THE IMPLEMENTATION PART === PRESENTATIONS ==== KNOWLEDGE ETC

There has to be a scientific approach, realistic, achievable and mutually agreed upon. Quantitative and qualitative factors have to be kept in mind and all parameters with time specific. Contributions made in terms of creativity and ideas also determines the employees' knowledge used creatively.

Agree with both answers given by Mr.:Zafar & Mr.:Rafaat  too

Agreed with all above.

Through well-defined KPIs, particularly:

1- Number of potential customers.

 2- Demand and supply management.

Agree to S M A R T
