How to introduce a traceability system for production?

Question

Business Informatics

It has the following chain:
1. Warehouse. The warehouse stores components for assembly.
2. Case production
department 3. Product assembly department.
How to make production traceability? That is, so that I could see what came to the warehouse and what is there? And if so, how is it competent to mark or track? Is it better to use barcodes or tags? How to keep track of who assembled the case, so that the moment of marking would take as little time and effort as possible? How to track the transfer of products between departments?
There is a small point, the production output is ultimately made up of small parts that are produced in these departments.
How can you keep track of all this?
