What kind of website development process do you need?

I wouldn't say I have super rich experience in website product planning, but from the perspective that a product manager is the soul of a product, I still hope to have an understanding and control over any aspect of the product. To understand the whole picture, one needs a relatively clear recognition process. The development process of a website may be known by everyone in this industry, but the extent to which each person knows it might be different. Therefore, I still made a rough sketch to give a basic description of my understanding of the website product development process for friends to refer to.
