What is the difference between agile development and traditional development?

Before the advent of the agile development model, developers have been using the traditional development model. Then, what is the difference between agile development and traditional development mode? What are the advantages of agile development?
1 The traditional development mode is driven by documents, while agile development https://www.ciandt.com.cn/ advocates writing less documents.
Traditional development mode: After developers and project participants receive customer development requirements, they will sort out a set of development documents in advance. The development process is carried out according to this document. During the process, customers basically do not participate in the acceptance and experience of the product. Only after the finished product is released, the project is handed over to the customer. Such a development model may result in that the final product developed is not what the customer wants, and then modifying it at this time will cause great problems.
Agile development mode: Develop according to the specified mode/process, write less documents, and only write necessary documents, and the problems in the traditional development mode can be completely avoided.
2 Agile mode adopts iterative development, and traditional mode adopts waterfall development.
Agile development takes the form of iterative development, that is, each stage has products that need to be completed at each stage and can be used. In this stage, only a few functions need to be developed, and other functions are not added, and the products of these functions must be available. For use, after the completion of this stage, the product will be delivered to the customer. After the customer has no comments, the next stage of development will be carried out.
3 The traditional development model believes that the development process is predictable, while the agile development model believes that the development process has many variables.
In the traditional development model, the software development process is deterministic and measurable. As long as you try to gather the required information and make a plan at the beginning, faithfully executing the plan should be successful. In the agile development model, the world is changing and there are many uncertainties.
What? The difference between traditional development and agile development is still unclear? After reading the picture below, you can understand:
As shown in the picture above, software is more like a living plant, and software development is a gradual and orderly process from the bottom up. The growth process is similar to the natural growth of plants.
Agile development follows the objective laws of software, continues iterative and incremental development, and finally delivers products that meet customer value. Just like the plant growth process shown in the picture above, it comes stage by stage, not a one-time delivery.
