The required Walmart case told straight — Pactum’s ~68% (company-reported), the scrapped Bossa Nova robots, the quiet Element platform — and all five discussion questions answered.
August 2026 · Case 5 of 6
As you read — hold this question
The set case sells Walmart’s AI as a clean success. What actually happened — and when a bot negotiates with your smallest suppliers, who holds the power?
~68%
of tail-end suppliers reached a deal with Walmart’s Pactum negotiation bot — a figure that is company-reported, not audited.
This is the set case study — and the honest version is more useful than the glossy one. A real win with a caveat, a scrapped robot the slides never mention, and the quiet platform that actually mattered. Then the five discussion questions, answered.
The set case
The textbook versionQuiz: the Walmart case
Pactum, the scrapped robot, and the quiet platform
Walmart Canada ran a pilot with an AI negotiation bot from Pactum, pointed at the thousands of small “tail-end” suppliers a human team never has time to sit down with. Walmart reported that about 68% of the suppliers it approached reached a deal (Harvard Business Review, 2022). Say the word out loud: reported — it hasn’t been independently audited.
And the arc the slides skip: for years Walmart rolled out Bossa Nova shelf-scanning robots — then scrapped the contract in November 2020, because humans did about the same job for less. The real win has a boring name: Element, Walmart’s in-house machine-learning platform, which cut the time to get a model into production from weeks to under an hour. No headline; just the plumbing worth copying.
Read the caveat
“~68% reached a deal” is company-reported (HBR, 2022), not independently verified. Use it as a signpost, not proof.
The honest arc
A scrapped robot (Bossa Nova, Nov 2020), a quiet platform (Element), a real win. AI in retail ops is not a straight line of wins.

The five questions you’ll be asked
The question
An exam-ready answer
1. Can Pactum-style negotiation work for SMEs?
In principle yes — the cloud lowers the cost — but small firms lack the supplier volume and data to train it. More likely via shared platforms or marketplaces than going it alone.
2. Ethics of dynamic pricing in an emergency?
Efficient, but it risks price-gouging and unfairness in a crisis. Needs clear guardrails, caps, and transparency about when and why prices move.
3. Keeping AI decisions transparent?
Explainable models, a genuine route to appeal, and simply disclosing that an AI is doing the negotiating or the pricing.
4. Reskilling displaced workers?
Move people from chasing to judgment — exception-handling, supplier relationships, oversight — backed by real retraining, not a slogan.
5. AI for resilience against pandemics / geopolitics?
It can sense disruption earlier and re-plan faster — but it can’t replace buffers, backup suppliers and slack. (See Case 6.)
The other side — the uncomfortable question
When a bot negotiates with your smallest suppliers — suppliers who don’t have bots of their own — who holds the power? Automated negotiation is efficient. It can also quietly tilt an already-tilted table further toward the giant. Efficient and fair are not the same word.
Quick recall — without looking back
Test yourself on this case
Question 1 of 3
What did Pactum do for Walmart, and what is the essential caveat on the headline number?
An AI bot negotiated with thousands of small “tail-end” suppliers (Walmart Canada); ~68% reached a deal. The caveat: that figure is company-reported (HBR, 2022), not independently audited.
Question 2 of 3
Give the honest three-part arc of Walmart’s AI story.
A scrapped robot (Bossa Nova shelf-scanners, cancelled Nov 2020), a quiet platform (Element, weeks→under an hour to production), and a real win (Pactum negotiation). Not a straight line of successes.
Question 3 of 3
State the power-asymmetry critique of automated supplier negotiation.
When a giant’s bot negotiates with tiny suppliers who have no bot of their own, efficiency can quietly tilt an already-uneven table further toward the giant. Efficient is not the same as fair.
