Revolutionizing Food Manufacturing: The Power of Integration Over Replacement

Key Takeaways:

• Integration beats replacement: Industry experts recommend phased integrations over disruptive replacements, yielding quicker returns.
• Success requires strategy, not spending: Industry leaders like Tyson Foods and Nestlé have achieved significant gains through smart integrations rather than complete overhauls.
• The failure trap is avoidable: Many digital transformation pilot initiatives falter because integration is misinterpreted as a barrier, rather than central to the transformation effort.

Your production line might have been operational for two decades without a hitch. However, increasing pressure for “digital transformation” in boardrooms may tempt you to consider a costly overhaul. Before you finalize that multi-million dollar commitment, take note: successful food manufacturers are integrating their existing systems instead of replacing them.

According to a survey by the Institute of Food Technologists, 53% of food manufacturers face challenges in integrating legacy systems, making it the second-largest hurdle to digital transformation, trailing only behind cost. This integration hurdle isn’t merely an obstacle to be bypassed; it’s an integral part of the transformative process itself.

Understanding Pilot Purgatory: The Digital Transformation Quandary

The food industry recognizes the necessity of digital transformation but is lagging in execution. Research from TraceGains’ 2024 Digital Drag report indicates that 60% of food and beverage companies remain ensnared in implementation due to outdated methodologies and complexities. Moreover, nearly 70% of industrial enterprises struggle to move beyond the pilot phase of their transformation initiatives.

The widespread stagnation can be traced to a fundamental misapprehension of digital transformation. Instead of perceiving it as a strategic integration challenge, many manufacturers approach it as a mere technology procurement endeavor.

“The notion that every technology implementation must be a lengthy project led by external consultants is an archaic mentality,” states Paul Bradley, Senior Director of Product Marketing at TraceGains. “Time is of the essence for food and beverage brands encumbered by outdated ERP systems that fail to meet today’s dynamic market requirements.”

The costs of missteps are particularly burdensome. Given the razor-thin margins prevalent in food manufacturing, companies can ill afford prolonged pilot programs that yield no results. Additionally, compliance with the Food Safety Modernization Act (FSMA) 204 traceability rule, due by July 2028, necessitates real-time data capture that legacy systems cannot provide.

Integration Success Stories: Proven Models

Companies that have reaped significant rewards typically share a common strategy: augmenting their existing systems with modern capabilities, instead of opting for wholesale replacements.

For instance, Tyson Foods, a global meat processing giant with $53 billion in revenues in 2024, faced a crisis with unreliable legacy servers that affected production across over 100 facilities. Instead of a total replacement, Tyson opted to integrate its systems with the Google Cloud Platform, deploying numerous Internet of Things (IoT) sensors throughout its plants. The initial factory integration was completed in just 1.5 months.

“Connecting operational data to IoT data points has enabled us to future-proof and modernize simultaneously,” the Tyson Foods team highlighted in their Google Cloud case analysis.

Similarly, Nestlé undertook the world’s largest SAP S/4HANA upgrade between 2024 and 2025. However, their strategy focused on integration rather than complete replacement. The upgrade was activated for over 50,000 users in 112 countries, all while maintaining existing operations. Nestlé constructed its IoT platform atop its legacy infrastructure, connecting a range of products from Nespresso coffee machines to smart pet devices.

“A unified ERP backbone allows for a common platform, enhancing visibility across our operations,” explained Chris Wright, Nestlé’s Chief Information Officer. “With AI and automation, we can expedite product launches and boost efficiency within our entire value chain.”

Even smaller manufacturers like Uncle Crumbles, a veteran gluten-free granola producer, have achieved remarkable improvements through strategic integration, raising their Safe Quality Food (SQF) score from 87 to 99 by integrating Oracle NetSuite ERP with existing production lines rather than replacing equipment.

Unique Challenges Favor Integration

Food manufacturing facilities present distinctive challenges that inherently favor integration over replacement. Production lines represent substantial capital investments and often comprise specialized machinery tailored for specific processes. A complete overhaul could erase decades of process improvement and institutional knowledge just when the industry grapples with severe workforce shortages.

Charles A. Horth, CEO of Factora, who has two decades of expertise in implementing manufacturing execution systems (MES), strongly opposes replacement strategies. He argues that given the considerable existing investments in physical, digital, and human assets, along with the risks associated with radical transformations, the pervasive “rip-and-replace” argument for IIoT should be put to rest immediately.

Instead, successful manufacturers can benefit from a defined integration architecture. Utilizing the ISA-95 framework—which outlines a hierarchy from physical processes through enterprise planning—combined with OPC UA (Open Platform Communications Unified Architecture) as the communication backbone enables them to:

• Add IoT sensors to existing machinery without mechanical modifications.
• Link previously isolated systems through middleware acting as protocol translators.
• Collate data from diverse sources for better analysis.
• Optimize operations based on insights garnered without halting production.

As outlined in Pemeco Consulting’s 2024 analysis, typical ERP implementations have payback periods ranging from 2 to 5 years, with 2.5 years being the average. On the other hand, targeted integration projects can yield faster returns, especially when addressing specific pain points like quality tracking or predictive maintenance.

A Step-By-Step Integration Roadmap

Phase 1: Initial Assessment and Quick Wins (Months 1-3)

Conduct a network scan to identify value drivers across your facilities. Deploy core MES functionality and begin IoT sensor placement on the highest-value equipment where downtime or quality issues have the most significant effects. Focus on non-invasive methods that do not require reprogramming of existing systems.

Phase 2: Integrating Systems and Building Intelligence (Months 4-8)

Connect quality management systems with production data, implement predictive maintenance on critical machines, and deploy advanced analytics for enhanced insights. Establish one or two “lighthouse” sites to test and validate concepts before larger-scale implementation.

Phase 3: Optimization and Scaling (Months 9-12)

Enable AI-driven optimization for scheduling and resource allocation, implement digital twin capabilities for process simulation, and replicate successful strategies across your enterprise using lessons learned from lighthouse sites.

According to research by McKinsey’s Global Lighthouse Network, successful transformations require concentrating on a handful of high-impact, synergistic use cases rather than disparate pilots.

Protecting Against Cyber Threats

Legacy systems were not designed with cybersecurity in mind, resulting in vulnerabilities that integration must address. Instead of replacing vulnerable systems, focus on implementing comprehensive security strategies, including:

• Network segmentation following the Purdue model to create secure demilitarized zones (DMZs) between information technology (IT) and operational technology (OT) layers.
• OT-specific security monitoring that comprehensively understands industrial protocols.
• Implementing a zero-trust architecture with multi-factor authentication for accessing systems.
• Using compensating controls for systems that cannot be patched.

Recent breaches affecting major food companies like JBS (2021) and Dole (2023) underscore the real and growing threat. The Elisity 2025 cybersecurity report emphasizes that food manufacturers are particularly susceptible due to the mix of legacy systems, narrow profit margins, and the critical nature of the food supply chain.

Transforming Integration from an Obstacle to a Solution

A successful digital transformation does not necessitate complete replacement. Instead, effective integration of your existing systems with necessary modern capabilities can help enhance performance, regardless of budget constraints. While it may seem that connecting legacy systems to contemporary platforms is merely a prelude to digital transformation, in reality, it is the transformation.
