Dear Usha Dcruz,
First and foremost, you need to establish the responsibilities and functions of each category of employee. Additionally, you should outline the expected quantitative and qualitative output or productivity from each category of employees.
Moreover, it is essential to define the policy for assessment, including who will conduct the assessment (self, supervisor, and manager), and the assessment period (fortnightly, monthly, bi-monthly, quarterly, half-yearly, or annually).
Lastly, ensure that there is adequate training and development for employees to enhance their performance and further develop their skills. You should also have a plan in place for the replacement of employees who do not meet performance expectations.
Thank you.
