Companies spend billions on ERP systems expecting miracles. Some get them. Others get disasters that cost hundreds of millions and make headlines. The difference between success and failure often comes down to how companies handle the implementation – not the software itself.
Walmart’s Custom-Built SAP Transformation
Walmart processes half a trillion transaction records. They’ve got 250 million customers walking through their doors every week, 11,000 locations worldwide, and 2.2 million employees to manage. Their old systems couldn’t handle this scale anymore.
Before their SAP implementation, Walmart ran on 27 different order management systems globally. Each one was heavily customized and poorly linked to headquarters in Bentonville. The company was spending millions yearly on a hybrid custom-built system that barely kept things running. These early systems were complex, costly, and took forever to execute basic tasks.
Walmart started with SAP in 2007 for back-office operations. They built a custom ERP called “FIRE” (Fast, Insightful, Reliable, and Easy) on top of SAP’s foundation. The system now integrates inventory management, supply chain, finance, and project management across their entire operation.
The results speak for themselves:
- Processing that used to take hours now happens in real-time across all 11,000 locations.
- Inventory management improved dramatically – they can track millions of products across global warehouses instantly.
- Financial processes that were manual and error-prone became automated, saving time and reducing mistakes.
- The company achieved substantial cost savings through automation and optimization of logistics.
- Customer satisfaction improved through better inventory availability and faster order processing.
Walmart Mexico implemented SAP Integrated Business Planning in 2024, eliminating system breakdowns and reliance on email exchanges and offline spreadsheets. Their quarterly revenue from just one product line jumped 345% year-over-year to $2.3 billion.
Nestle’s $325 Million Recovery Story
Nestle USA was a mess before their ERP attempt. They had 230,000 employees at 500 facilities in 80 countries, all operating independently. Different divisions used different systems – they found nine different general ledgers and 28 different points of customer entry. Each factory acted like its own company.
In 1999, Nestle started their “BEST” (Business Excellence through Systems Technology) project with SAP. The budget was $200 million. They were supposed to finish by Q1 2003. Instead, everything went sideways fast.
What went wrong:
- Nobody talked to the employees who’d actually use the system.
- Different departments fought each other instead of working together.
- They rushed the integration and skipped critical testing phases.
- Employees had no idea how to use the new system when it launched.
- The company had to halt the entire rollout midway through.
Nestle stopped everything and started over. They brought in the right people, actually trained their staff (180 hours of mandatory training for customer service reps), and took their time with the implementation. They rolled out SAP’s Apparel and Footwear Solution gradually, starting with Canada in 2000, then North America in 2002.
The turnaround was massive:
- Cost savings of $325 million by 2002.
- All USA divisions finally used the same system.
- Better sales and demand forecasting across the board.
- Standardized training and procedures company-wide.
- By 2004, 10% of Nestle’s global business operated with standard procedures and data systems.
- System recovery time dropped from six hours to under ten minutes.
- 95% of annual review processes became automated across 100+ countries.
Nike’s $100 Million Supply Chain Disaster
Nike had 27 order management systems globally by 1998. Their nine-month manufacturing cycle was getting harder to manage as the company grew. They decided to modernize with i2 Technologies’ supply chain software in 1999, paying $10 million upfront with a total project cost of $400 million.
The implementation was a complete disaster. Nike went live in 2001, right before their busiest season. The software couldn’t handle Nike’s complexity – it took up to a minute for a single entry to be recorded. Different modules used different business rules and couldn’t talk to each other properly.
The damage was brutal:
- $100 million in lost sales in Q3 2001.
- Stock price dropped 19.8% immediately after announcement.
- Quarterly profits missed by 28%.
- Nike flooded the market with unpopular shoes while popular styles sat unmade.
- Retailers couldn’t get orders filled even though inventory existed.
- i2 Technologies’ stock crashed 22.4% on the news.
Nike ditched i2’s demand planner for short and medium-range planning by spring 2001. They moved those functions into SAP’s R/3 ERP system, which focused on actual orders and invoices rather than predictive algorithms. The recovery took six years and $500 million total, but by 2004:
- Inventory levels declined steadily while margins improved.
- Gross margins increased from 39.9% to 42.9%.
- Design and manufacturing became quicker and more responsive.
- The project was 80% complete and delivering real benefits.
- All regions successfully migrated to the new system without disruptions.
Hershey’s Halloween Nightmare
Hershey wanted their new ERP system ready before Y2K. They gave themselves 30 months instead of the recommended 48 months. They picked three systems – SAP’s R/3 ERP, Manugistics’ supply chain management, and Siebel’s CRM – and decided to launch all three simultaneously in July 1999.
July 1999 was when Hershey received most of their Halloween and Christmas orders. The timing couldn’t have been worse. The rushed implementation meant they skipped critical testing phases. When the systems went live, orders couldn’t flow through properly.
The failure was spectacular:
- $100 million worth of Kiss and Jolly Rancher orders couldn’t be fulfilled.
- Products sat in warehouses while store shelves stayed empty.
- Q3 1999 profits dropped 19%.
- Stock price fell 8% immediately.
- The disaster made the front page of the Wall Street Journal.
- Revenue dropped 12% compared to Q3 1998.
- Analysts lost confidence in the company for nine months.
Different departments fought with each other during implementation. Systems testing failed. Data migration had errors. Employees received inadequate training – they didn’t know how to use the system when it launched during the company’s busiest period.
Coca-Cola’s Global Integration Success
Coca-Cola operates in over 200 countries with 3,900 different beverage products. Before SAP, they ran on legacy systems with fragmented data, delayed reporting, and no real-time insights. Manual order processing was slow and error-prone. Each bottler operated independently with different systems.
Coca-Cola implemented SAP ERP systematically, focusing on specific objectives:
- Automate the entire order lifecycle from entry to fulfillment.
- Get real-time visibility into inventory and production.
- Integrate financial processes across all markets.
- Standardize operations across bottlers globally.
Coca-Cola Hellenic Bottling Company (their European bottler) saw dramatic improvements after implementing SAP:
- Reduced time spent on administrative tasks by 30-50%.
- Automated 95% of review processes across 15,000 managers in 100+ countries.
- Cut daily batch workload from 300 to 180 jobs.
- System recovery time dropped from six hours to under ten minutes.
- Successfully expanded to 26 countries with 1,200 additional users.
The implementation worked because Coca-Cola took a phased approach. They started with pilot programs, trained employees properly (unlike Hershey and Nike), and didn’t rush the timeline. They also kept their existing systems running during the transition, avoiding the “big bang” disasters that hit other companies.
What Actually Makes the Difference
Looking at these five companies, the pattern is obvious. Success or failure had almost nothing to do with which ERP system they picked. Walmart, Nestle, Nike, and Coca-Cola all ended up with SAP. Hershey failed with SAP too, at least initially.
The companies that succeeded:
- Took their time with implementation (Coca-Cola, Walmart).
- Trained employees thoroughly before going live.
- Ran pilot programs and fixed problems before full rollout.
- Kept old systems running during transition periods.
- Had strong project management and clear communication.
The companies that failed:
- Rushed implementation to meet arbitrary deadlines.
- Launched during busy periods (Hershey, Nike).
- Didn’t test systems properly before going live.
- Failed to train employees adequately.
- Had poor communication between departments.
Even the failures eventually recovered. Nestle turned their disaster into $325 million in savings. Nike rebuilt their supply chain stronger than before. But they all paid heavily for their mistakes – in money, time, market share, and reputation.
The real lesson?
ERP software is not a one-size-fits-all solution; it’s typically customized to fit the unique needs of each business, and a quality ERP software company can offer tailored solutions. Whether it’s for a manufacturing giant or a small retail chain, ERP systems are designed to scale and adapt to different industry requirements. This adaptability ensures that businesses can mold the software to their specific workflows, thereby maximizing its effectiveness.
ERP implementation isn’t about the software. It’s about how you manage the change. Companies that respect the complexity, invest in their people, and take the time to do it right succeed. Those that rush, cut corners, and ignore their employees end up as cautionary tales in business school case studies.
