Retail QA case studies, analysed with one fixed skeleton

Terms used in the systems column and filters: POS (point of sale: the till software and hardware that rings up store sales, takes card payments and prints receipts.), OMS (order management system: software that routes, splits and tracks customer orders across stores, warehouses and carriers.), WMS (warehouse management system: software that runs receiving, storage, picking and shipping inside a distribution center.), D2C (direct to consumer: a brand that sells its own products online to shoppers without a retailer in between.).

6 further verified cases count toward D1 but have no page, because the site gives at most 8 pages per vendor; they are in the case-studies.json download. Every case is a real case study published by the vendor, opened and checked on the date shown on its page. The site writes no cases of its own and does not name clients the vendor kept anonymous.
