1. First of all, the product manager's understanding and familiarity with the business is very important.
Currently common systems are:
Account system,
order system,
point system,
data analysis & visualization system,
anti-spam system,
billing system,
content management system (tags, SKUs, categories, articles, etc.)
Third-party authorization system.
According to the business logic, these systems are assembled together like components to complete the product architecture.
For example, there are SKU management, category editing, order system, reconciliation, etc. in e-commerce. There are exchange rates, bill cutting, customs clearance, etc. in Haitao. In the advertising industry, what are CPD, CPC, CPM, CPA, DSP, and DMP, and how do they work? In catering, what are pre-dinner, post-dinner, and in-meal marketing?
These things need to be learned. Books, blogs, Zhihu, seniors, and competing products can all provide very good references.
In the end, it takes practice to go to the pit.
When you are familiar with the various aspects of this industry, understand the position of your company in the industry, and have accumulated a large number of standard systems, the product architecture capability will naturally improve.
