Hi,
for starting a new department, you can follow the below basic steps:
1)decide on various functions in HR for which you want to hire. Eg: on the basis of the employee strength, you can keep 1 person for recruitment, onboarding and employee relations.
I suggest, for statutory and payroll, you can keep one employee.
2)once you decide on the roles, please define the job description of each position. It is very important to demarcate the work and the roles as it reduces ambiguity.
3)prepare a vision and mission for HR which should be derived from the Organisation mission.
4)broadly, in an employee life cycle, you see the activities- recruit, Induct, Assess, develop, retain, exit.
considering these broad topics, prepare processes for each activity.
Remember, it is always easy to follow documented procedures.
The list can be endless. In case you require any help, feel free to mail me on ruchikas.sharma@gmail.com
Best of Luck
