Problem as stated

The retailer was running a digital transformation that tied many downstream applications together, including warehouse and delivery integrations. It also replaced its legacy POS estate in 150 stores while the old system stayed in support. It sold through a website, stores, home delivery and Click & Collect, and needed a test program and strategy run by an outside partner. [ev-1213]

Reading notes for a buyer

Over what period and how many releases were the integration-stage defect and live defect figures measured? [ev-1213]
