Hi Ashok.
It's okay if you don't have a background in Product Management and you can switch to careers in the same.
You need the relevant skill sets, management abilities, multitasking abilities, and know market research.
The role of product managers includes conducting research, structuring the strategy or plan, communicating the plan within the organization, moving towards the decided plan or strategy then finally analyzing what worked and what didn't work.
To go ahead with a career in Product Management; firstly, acquire the relevant skills, take up projects and make a portfolio.
