In the previous production process of Internet companies, we can macroscopically divide the R&D team into two parts: the front-end and the back-end.
The so-called front desk is the part of the product that users directly contact, such as apps that can be downloaded in the app store, such as WeChat, Douyin, Taobao, or websites that can be used.
The user's cognition and experience of the product are also born from this. For example, everyone's understanding of WeChat is what the front-end APP shows for everyone: an application with a green icon, which contains my friends A, B, and C.
The background consists of two parts:
The general term for the internal management services of the enterprise, such as: internal CRM, ERP, etc.;
Provide service capabilities for the foreground, such as: data compression capabilities, concurrency, etc.
The most important feature of the background is phone number list that the services it provides are not perceived by ordinary users, just like users will not remember the WeChat brand because of the concurrency and transmission speed of applications.
After figuring out the concepts of front-end and back-end, we can use a picture to describe the product service model of the front-end and back-end models:
In general, it provides capabilities and calculations in the background of the application, and the foreground encapsulates the capabilities of the background and displays it to users in a graphical form, so that users can more easily use the services provided by the company to solve their personal needs.
