What was the process of working on the new acceptance stage feature?

The process of working with a feature for adding a new acceptance stage typically includes the following steps:

1. Requirements gathering — discussion with the business customer or users to understand why the new stage is needed, what data and conditions it should consider.
2. Analysis and design — determining how the new stage will fit into the current acceptance process, what changes are needed in business logic and interface.
3. Development — implementing changes in the system, adding the new stage to the workflow, updating forms and business rules.
4. Testing — verifying the correctness of the new stage, including functional and integration testing.
5. Deployment and training — deploying the changes to the production environment and training users to work with the new stage.

For example, if a quality check stage is added to the product acceptance system, first, the quality parameters to be controlled are clarified, then a form for entering the inspection results is designed, the logic for transitioning to the next stage is implemented only upon successful inspection, and then everything is tested and launched into operation.
