A data product manager should ideally have a background in data science, as they will be responsible for overseeing the development of data products from start to finish. They should also be well-versed in the latest trends and technologies in the data product space, as this will help them to make informed decisions about which products to develop and how to best market them. In addition, a data product manager should have strong project management skills, as they will be responsible for ensuring that data products are developed on time and within budget.
