Sprint 3 was used to implement a lot of the missing features as well as expand and polish the existing ones. The order picking feature was expanded with:

• Support for serial numbers
• Multiple barcodes in one scan
• General UI polishing
• Getting product images per order item

Two other features were also added:

• Stock mutation feature
• Stock transfer feature

With this I was finally able to cross off most of the "must" requirements though sadly not all. Time was starting to run low so the focus had to be shifted to polishing and documenting after this sprint concluded.
