01The brief

A hypermarket strategy that needed the customer's voice, at scale

Pick n Pay's Customer Insights team runs research on shoppers, store formats and brands for the wider business. In late 2025 it came back to Yazi, after an earlier project together, to help the Hypermarkets division understand its customer value proposition: why shoppers choose Pick n Pay Hypers, and why others shop elsewhere.

The study had to give stakeholders the sample they look for: in Customer Insights Manager Leilah Pandit's words, a good couple of hundred people, and a couple of thousand is even better. And it had to reach people who don't shop at Pick n Pay Hypers as well as those who do.

02The challenge

Large samples and real reasons rarely come from the same study

Shoppers and non-shoppers

Reaching people who shop elsewhere is harder than surveying loyal customers.

Sample size matters

Senior stakeholders trust findings from hundreds or thousands of people, not a few focus groups.

The reasons behind the choice

A tick-box survey shows where people shop. The team needed to hear why.

Ready for decision-makers

The findings had to be clear enough for the Hypers marketing lead to act on.

03The approach

AI interviews on WhatsApp, for shoppers and non-shoppers alike

Yazi ran the study as an AI interview on WhatsApp, alongside a short profile survey. Participants answered at their own pace, and the AI Interviewer followed up on each answer to get to the reason behind it: what draws people to a hypermarket, what brings them back, and what sends them elsewhere.

One conversation per shopper

Every participant got a follow-up question, not just the ones a researcher had time to call.

1
Profile. A separate short survey captured who participants are and where they shop.
2
Interview. The AI Interviewer explored the hypermarket experience by text or voice.
3
Follow up. Thin answers got a follow-up question instead of a skip.
4
Report. Yazi analysed the interviews and reported findings by shopper group.

Straight into the strategy session

The Hypers marketing lead used the findings in his strategy session at the end of February 2026. The study reinforced the operational strategy already in planning, highlighted opportunities for the year ahead, and surfaced a competitor trend that wasn't on the team's radar, which is now part of the Hypers strategy.

“Our stakeholders always want a good sample, a couple of hundred, a couple of thousand is even better, and I'm extremely happy with that.”

Leilah Pandit, Pick n Pay

“It reinforced the operational strategy and highlighted a few opportunities for what we need to do going forward, which was extremely valuable to him.”

06Impact

A strategy backed by more than 1,300 voices

For Pick n Pay

A marketing strategy for Hypers backed by the voices of more than 1,300 people, and a competitor trend spotted early enough to act on.

For shoppers

People shared what they want from a big shop in a few minutes on WhatsApp, in their own words, without a phone call or a long online form.

“

Overall it was a very good piece of work. He used it in his strategy session at the end of February, so from a marketing standpoint he has a clear direction on what he needs to do, and it's backed up by the voice of the customer.

Leilah Pandit, Customer Insights Manager, Pick n Pay
07Conclusion

Big samples and real reasons, in the same study

Retail strategy teams usually choose between a large survey and a handful of focus groups. Pick n Pay's Hypers study had both: a sample big enough for its stakeholders, and a conversation with every participant about why they shop where they do.
