Bug solved method
The previous incremental software development method based on SOP has several issues:

• Inconvenient human-computer interaction. New user requirements, technical demands, bug fixes, and added design constraints are difficult to directly correspond to the relevant SOP steps for operation.
• Inflexible programming languages. The same design cannot be easily switched to different programming languages, mixed-language programming is not supported, and design solutions cannot be reused.

To address this, we propose a more practical solution.
It is an upgraded version of DI (Data Interpreter) called RoleZero, which will be released soon. It adopts the following methods to handle software development issues with real-time human-computer interaction:

1. Generate sequence diagrams from requirements. This compresses the content size of requirement descriptions and supports flexible changes in requirements and switching between programming languages.
2. Generate code from sequence diagrams rather than directly from user requirements. This approach supports design outputs reuse, can flexibly generate code in different languages, allows for additional technical requirements during code generation (such as which packages must be used, how interfaces should be utilized, etc.), and supports mixed programming languages.
3. Bug modifications can be implemented through human-computer interaction, directly targeting specific files.
4. Regarding the coding of the UI, you can use RoleZero to convert UI pictures into code, and then merge them into the backend code generated based on the sequence diagrams through human-computer interaction.

Design Outputs Demo
Here is an example of a sequence diagram generated by RoleZero based on real software development requirements giving a user requirement PDF file and an external system interface usage PDF file, to help everyone understand RoleZero's capabilities in interpreting requirements.

Subsequent issues related to new requirements or bug fixes will be consolidated under this issue for further follow-up.

although PDF is a awesome file/document format, I personally think a json or etc would be better.

Because I am scared that the pdf parser could be too complex to use/maintain (especially compatibility).

PDF is originally by adobe,so i think we must make sure the save format is https://www.iso.org/standard/75839.html

But,it's at least better than docx or .yaml.

I think we are heading to the right direction.But, this seems to only showcase the legal SOP situation with systeminterfaceusage..pdf ?

We choose to use PDF because in reality, most software requirements are archived and transferred using docx or PDF documents, so this is an adjustment based on the real-world situation.

PDF is just a file format, it does not define the content.

However, in reality, the description of software requirements often has various issues, and it needs further improvement. Compared to requirement documents, interface specifications are easier to use directly. So sometimes we do not directly use the requirement document because the requirement description in it still has problems that need to be further resolved.

i see. will wait for the release and test it out.
