How PepsiCo South America Cut Its Accident Ratio 50% in 6 Months by Changing Leadership Routines

The ILO estimates nearly three million work-related deaths each year, which is why a 50% drop in one operation matters only when the leadership system behind it also changed. The PepsiCo South America result matters for that reason. It was not a poster campaign, and it was not a training burst. It was a leadership reset that made field decisions harder to hide and easier to challenge.

Across 25+ years leading EHS in multinationals, Andreza Araujo has seen that organizations rarely fail because nobody cares. They fail because the work system rewards convenience, and the people closest to the hazard learn to survive by adapting. In Safety Culture: From Theory to Practice, Andreza argues that culture is visible in repeated choices. In The Illusion of Compliance, she shows why a clean record can still hide weak control.

Initial scenario

The raw problem was not a lack of rules. PepsiCo South America already had a large enterprise, a mature brand, and enough management structure to produce reports, campaigns, and inspection files. The real problem was that the organization still had to make risk visible in a way that local leaders could not ignore, because a paper trail does not stop a shortcut by itself.

That is where the case becomes useful for executives. Many companies ask whether they have enough training, but the better question is whether the leadership rhythm actually notices drift before the drift becomes routine. The related article on safety culture survey vs maturity vs field evidence explains why perception data alone cannot answer that question. A case like this one shows why field proof matters more than comfortable averages.

The practical aim was simple to say and hard to execute. The site had to stop treating safety as a specialist message and start treating it as a line-management decision. Once that shift is real, the result can move quickly. When it is only verbal, the dashboard improves while the work stays the same.

Decision

The key decision was to stop asking the organization for another safety push and start asking leaders to own the way work was actually being decided. Across 25+ years in executive EHS, Andreza Araujo has seen that the fastest gains come when leaders change the routine that produces the risk, not when they ask workers to care harder.

That means the leadership question changes. Instead of asking who needs more awareness, the business asks which decision keeps repeating the same exposure, who owns that decision, and what field evidence will prove the decision changed. James Reason's latent-failure lens fits this case because the visible symptom sits on top of earlier choices about planning, supervision, escalation, and verification.

The article on how to build a safety decision rights matrix in 30 days is the closest operational companion here. A case study like PepsiCo South America only becomes repeatable when line leaders can see where they are expected to decide, where they must escalate, and where they are no longer allowed to improvise.

How the work changed

The result did not come from a single slogan. It came from a cluster of leadership choices that made the field harder to fake. Supervisors were expected to verify what they could actually see, local leaders had to answer to the quality of the decision rather than the volume of the report, and weak signals were treated as a management duty instead of a background complaint.

That is the point where many organizations miss the mechanism. They celebrate the reduction, but they do not name the habits that produced it. In this case, the shift was toward visible responsibility, tighter escalation, and more direct challenge to the kind of normal workarounds that quietly grow into serious exposure.

As described in Safety Culture: From Theory to Practice, culture becomes measurable when the same decision is repeated under pressure. That is why the PepsiCo South America result is more useful than a generic success story. It shows that a company can move the work if the line leaders change what they verify, what they tolerate, and what they stop.

The article on risk review cadence how to build it in 30 days fits here because a good result needs a rhythm. If leaders do not review the right evidence on a fixed cadence, the organization drifts back to what is easiest to measure rather than what is safest to run.

What the six-month window actually changed

The six-month window mattered because it was short enough to expose whether the change had teeth. A 50% reduction in accident ratio during that period suggests that the organization did more than improve language. It changed how risk was being handled in daily operations, which is where the signal becomes credible.

The better reading is not that the site became perfect. The better reading is that the site changed enough of the management chain to reduce exposure at speed. In more than 250 cultural transformation projects supported by Andreza Araujo, that is usually the difference between cosmetic progress and a result that survives the next production push.

That table is the real lesson. A company can show certificates, dashboards, and attendance, yet still fail to prove that the work changed. The case only matters because the operating logic changed enough for the metric to follow.

Generalizable lessons

The first lesson is that training alone was never the engine of the result. Training can help, but only if the field conditions, the supervisor routine, and the escalation path also change. Otherwise the organization teaches the same people how to survive inside the same weak system.

The second lesson is that visibility beats reassurance. If a leader can see the same risk in the same place on every walk, then the organization is not learning. It is accommodating. In Patrick Hudson's maturity language, that is the difference between dependent compliance and a more distributed sense of ownership, and the practical test is whether the site can sustain challenge when the schedule tightens.

The third lesson is that the result becomes repeatable only when line leaders own it. EHS can support, coach, and verify, but EHS cannot substitute for the person who runs the work. If the supervisor is not the owner of the next decision, the improvement is too fragile to survive the next busy week.

The fourth lesson is that a strong case study needs a stronger operating loop. The article on safety decision rights matrix helps explain why. Once a company can name who decides, who verifies, and who escalates, the same kind of 50% result becomes less dependent on heroics.

Common traps leaders still repeat

The first trap is to celebrate the number and ignore the mechanism. A lower accident ratio is useful only if the organization can explain what changed in supervision, escalation, and verification. Without that explanation, the result is a lucky snapshot instead of a capability.

The second trap is to hand the story back to EHS. That feels tidy, because EHS is the safety function, but it misses the point. In this case, the real shift belonged to leadership routines, which means the improvement must be owned where the work is actually decided.

The third trap is to treat a good six-month result as proof that the system is now mature. It is better to treat it as proof that the system can change when leaders focus on the correct decisions. Maturity is not a claim. It is repeated performance under pressure.

The fourth trap is to let the result become a marketing line. The Illusion of Compliance is the right warning here, because paperwork can look elegant while the field continues to absorb the same risks. If the story becomes a slogan, the next weak signal will arrive in the same old way.

What to apply in your operation

If you want to apply the same logic, start with one question. Which leadership decision in your operation keeps reproducing the same exposure? Do not start with a campaign. Start with the decision, the owner, the proof, and the review date.

Then use the next shift to test the answer in the field. Ask supervisors what they actually verify, ask operators what they feel allowed to stop, and ask managers which weak signal would force them to change the plan before an injury occurs. That is the kind of operational conversation that turns a case study into a control system.

The article on stop work authority 6 myths that keep crews silent gives the next step once the decision is clear. A strong stop-work rule keeps the change alive after the initial excitement fades, which is when many good stories are otherwise lost.

If your operation needs a practical reset, start with Andreza Araujo's books, then move to the field. Safety Culture: From Theory to Practice gives the logic, and The Illusion of Compliance shows why the logic must be tested where work is done. For leaders who want the process turned into a real diagnostic, the fastest next step is to request help from Andreza Araujo.
