Size indicators

The client description and size indicators are quoted from the source; segment, region and channels are this site's classification. [ev-1790]

Systems in scope

• Loyalty: named in the client description ("an established membership rewards program that offers discounts, point accumulation, and exclusive benefits") and the solution ("multi-device digital membership registration portal")

Problem as stated

A Japanese supermarket chain signed up members for its rewards program only on paper forms in store. Many shoppers gave up partway through the form, there was no way to register online or by phone, and store staff had no digital tool to help customers register. [ev-1790]

Staff lacked a digital tool for assisted registration (quoted from the source)

Reading notes for a buyer

This case speaks to the scenario “First outsourced QA team for a mid-size retailer” and feeds dimension D2 (Retail system coverage) of the methodology. A question to put to SHIFT ASIA:

What did the testers cover beyond registration forms, such as the link to existing membership data, and were any tests automated? [ev-1790]
