Does a Product Manager Need Data Science?

Question

data mining

The fork of personal development is to buy a big expensive three-month course on Big Data or product management.
More interested in product management.
1. it is clear that there is no extra knowledge, but there is no extra money, effort and time either.
2. Is a serious immersion in data science really useful for a product manager, or is learning the basics and a few good books enough?

Answer 1

The right product manager, of course, needs data science.
Just don't buy Russian courses. At all. None.
Coursera, udacity and even youtube have a huge number of courses from reputable companies and universities for all skill levels.
First, you need to know data science in order to understand what is generally possible to learn about a product, client, process, and what is not, what can be calculated and what is not, what can be predicted and what is not, and also how, in what and how much you can and cannot be wrong.
Secondly, data science will teach you to think structurally and analytically about the client, not as a black unpredictable box, but as a subject with dynamically changing behavior that can be digitized, and therefore analyzed.
Thirdly, it will become clearly clear that you can analyze a lot, for a long time and even interesting, but if this does not translate into new actions in relation to the client, then the entire analysis and all the collected data are meaningless and useless.
