Why Digital Transformation Succeeds When People Investment Outweighs Technology Spending

By Staff Writer | Published: March 27, 2026 | Category: Strategy

Leading manufacturers invest roughly four times as much in process and people enablers as they do in new technology. Heres why that ratio matters and what it means for your transformation strategy.

Title: Why People and Process Matter More Than Tech in Digital Transformation

The numbers tell a striking story. For every two dollars that successful manufacturers spend on technology innovation, they allocate three dollars to reducing process debt and five dollars to scale and adoption. This 4:1 ratio of people and process investment to technology spending represents perhaps the most significant finding from McKinsey’s latest analysis of the Global Lighthouse Network, a World Economic Forum initiative tracking nearly 200 exemplary manufacturing sites across 33 countries.

The implications challenge much of the conventional wisdom surrounding digital transformation. While technology vendors and many consultants continue to emphasize the latest tools and platforms, the evidence suggests that sustainable competitive advantage comes not from the technology itself but from how organizations prepare their people and processes to extract value from it.

The Real Cost of Technology-First Approaches

The article by Dinu de Kroon, Enno de Boer, and Rahul Shahani introduces an important concept for operations leaders: process debt. Just as chief information officers have learned to manage technical debt—the accumulation of disjointed systems requiring eventual integration and reconciliation—chief operating officers now face an analogous challenge when deploying new technologies without corresponding process redesign.

Process debt represents the efficiency tax organizations pay when they layer new capabilities onto fundamentally unchanged workflows. A predictive maintenance algorithm deployed into a reactive maintenance culture generates alerts that go unheeded. An advanced production scheduling system feeding into manual handoff processes creates bottlenecks rather than relieving them. Real-time quality monitoring tools lose their value when quality engineers lack authority or processes to act on the data.

This phenomenon helps explain why Harvard Business Review research continues to show that approximately 70% of digital transformation initiatives fail to achieve their objectives. The failure lies not in the technology, which typically performs as designed, but in the organizational context receiving it. Without deliberate process redesign and workforce enablement, even the most sophisticated digital tools generate limited value.

The Lighthouse companies demonstrate a different approach. They invest first in streamlining the interactions between people and material flows, ensuring that data generated by new sensors reaches employees positioned to act on it. They redesign data flows to enable both people and material movements, recognizing that clean, well-structured data reflecting actual physical processes delivers more value than sophisticated algorithms operating on messy, inconsistent inputs.

Building Capability Rather Than Buying Solutions

A notable shift has emerged in how leading manufacturers approach digital capability development. The McKinsey analysis shows that Lighthouse companies now develop solutions in-house 37% more often than they did from 2019 to 2020, with particular emphasis on roles related to artificial intelligence architecture, design, and integration.

This trend toward insourcing reflects several strategic considerations. As AI tools become increasingly commodified, differentiation shifts from the tools themselves to how they are configured, integrated, and deployed within specific operational contexts. Generic solutions purchased from vendors rarely account for the nuances of individual production environments, supplier relationships, or workforce capabilities that determine whether a digital solution delivers transformational value or becomes shelfware.

Moreover, owning the information value chain provides strategic flexibility. Organizations that depend entirely on external vendors for digital solutions face ongoing licensing costs, limited customization options, and restricted ability to integrate across systems. By developing internal capabilities, Lighthouse manufacturers can modify solutions rapidly as conditions change, integrate across previously separate systems, and capture learning that informs future innovation.

This approach requires significant investment in talent. The research shows that Lighthouse companies hire an average of 25 new transformation roles per 1,000 factory full-time equivalents. Critically, nearly half of these roles focus on business and operations rather than pure technology functions. The mix includes agile coaches, business owners, business translators, product managers, and transformation leaders alongside automation specialists, data engineers, and data scientists.

This balance reflects a crucial insight: digital transformation is fundamentally a business transformation enabled by technology—not a technology project with business implications. The most sophisticated algorithm provides zero value if business leaders cannot articulate the right problem to solve, if process owners cannot redesign workflows to leverage the insights generated, or if frontline workers cannot interpret and act on the recommendations produced.

The Power of Composable Assets

Lighthouses have learned to navigate a critical tension in digital transformation: every operation is unique, requiring customized solutions, yet economies of scale demand standardization. The resolution comes through composability, a design principle emphasizing the ability to assemble and reassemble modular components.

The software industry pioneered this approach decades ago through practices like microservices architecture, application programming interfaces, and containerization. Leading manufacturers now apply these same principles to operational technology, creating flexible, reusable assets that can be rapidly configured for local contexts while maintaining consistent underlying foundations.

Consider predictive maintenance as an example. Rather than building completely custom solutions for each piece of equipment, Lighthouse companies create composable assets including standardized data models, sensor integration protocols, machine learning pipelines, and user interface components. Local teams can then assemble these components into configurations matching their specific equipment, maintenance processes, and workforce capabilities without rebuilding from scratch each time.

This assetization approach accelerates deployment dramatically. The article notes that nearly every new Lighthouse in 2024 has solutions for production scheduling, predictive maintenance, or facilities management among their top five applications. These use cases have matured to the point where proven playbooks exist. The competitive advantage comes not from solving these problems for the first time but from solving them faster, at greater scale, and with better adoption than competitors.

Low-code and no-code platforms play an increasingly central role in this strategy. Seventy-six percent of the 2024 Lighthouse cohort has deployed these technologies, enabling frontline workers without programming expertise to create, modify, and optimize applications. This democratization of development capability addresses a critical bottleneck: many pain points in production are hyperlocal, understood deeply only by on-site operators who work with specific equipment daily. Empowering these workers to make direct adjustments captures knowledge that would be lost or distorted through multiple layers of translation to remote development teams.

Human-Centric Design as Competitive Advantage

Perhaps the most significant mindset shift distinguishing Lighthouse companies involves their approach to workforce engagement. Rather than viewing digital transformation as something done to workers, these organizations treat it as something done with workers, designing systems that augment human capabilities rather than replacing them.

The data supporting this approach is compelling. Since 2020, Lighthouses have dedicated an average of 10% of their use case portfolio specifically to workforce priorities including worker experience, skill development, safety, skill augmentation, and work augmentation. More than 75% deploy solutions spanning all dimensions of the frontline experience. The returns include 10% to 20% reductions in non-value-added tasks and 25% to 30% improvements in labor productivity.

These results stem from deliberate design choices. Lighthouses rebalance the typical mix of tasks to emphasize technical and reasoning skills while automating away tougher, non-value-added, or dangerous work. They design out hazards and workplace barriers, creating more inclusive environments. They equip frontline operators with user-friendly decision-making and troubleshooting tools, recognizing that what matters most is not the sophistication of the model but how effectively the intended user interacts with it.

The role of change agents proves particularly critical. These individuals function as bidirectional conduits between frontline workers and management. They deliver key messages from leadership, address questions, and support peer education. Conversely, they relay frontline ideas, feedback, and sentiment back to transformation leadership, shaping implementation approaches to fit local contexts. For Lighthouse companies, change agents participate in technology demonstrations, deliver incentives and awards, lead ideation sessions, and speak at town halls.

This investment in change management reflects an understanding that user adoption and model adoption must develop in tandem. It is insufficient for solutions to work once; they must demonstrate ongoing value to operators, or they will be abandoned. Sustainable impact requires that frontline workers not only understand how to use new tools but also trust that the tools actually help them perform their jobs more effectively.

Challenging the Conventional Wisdom

The Lighthouse findings invite scrutiny of several prevailing assumptions in digital transformation discourse:

Implementation Considerations for Business Leaders

For executives evaluating their own digital transformation strategies, several implications emerge from the Lighthouse research:

The Broader Context of Manufacturing Transformation

The Lighthouse findings align with broader research on organizational change and technology adoption. MIT Sloan Management Review research identifying culture and people challenges as primary barriers supports the emphasis on workforce investment. Gartner’s work on technical debt validates the concept of process debt and the importance of addressing it proactively. BCG’s research on human-machine collaboration reinforces the value of augmentation over replacement approaches.

However, it is worth noting tensions in the research literature. Some scholars argue that in rapidly changing environments, the optimal strategy may involve rapid experimentation with multiple technologies followed by selective scaling—accepting that some investments will fail but prioritizing speed to learning over efficiency in deployment.

Additionally, the emphasis on in-house development may not be feasible or optimal for all organizations. Smaller manufacturers may lack the resources to build sophisticated internal capabilities. Companies in industries where technology provides limited differentiation may reasonably choose to rely more heavily on vendor solutions. The key is making these choices deliberately based on strategic considerations rather than defaulting to whatever approach seems most common.

Looking Forward

The continued growth of the Global Lighthouse Network from 16 sites in 2018 to nearly 200 today demonstrates that sustainable, scalable digital transformation is achievable. The consistent patterns emerging across these exemplary sites provide validated playbooks that other organizations can adapt to their contexts.

What remains clear is that technology alone will never be sufficient. The manufacturers achieving transformational results are those that invest as heavily—or more—in the people who will use technology and the processes that will be transformed by it. They resist the temptation to chase every new trend, instead focusing on solving real business problems with appropriate tools. They build internal capabilities while partnering strategically with external providers. They design composable assets that balance standardization with flexibility. They treat frontline workers as transformation partners rather than transformation subjects.

For business leaders navigating digital transformation, the message is both challenging and encouraging. Challenging because it means that sustainable transformation requires more than technology budgets; it demands fundamental reconsideration of how work is organized, how capabilities are developed, and how people are engaged. Encouraging because it means that lasting competitive advantage comes not from access to technology, which competitors can also purchase, but from organizational capabilities that are far more difficult to replicate.

The 4:1 investment ratio serves as a useful rule of thumb, but the deeper insight is that digital transformation succeeds when organizations recognize it as fundamentally an exercise in organizational change enabled by technology rather than a technology project with organizational implications. Those who grasp this distinction and invest accordingly are the ones who will join the ranks of the Lighthouses, while those who continue to focus primarily on technology will likely join the 70% whose transformations fail to deliver expected results.

The choice for business leaders is clear: invest in your people and processes at least as much as in your technology, or prepare to explain why your digital transformation delivered disappointing returns despite deploying all the latest tools. The evidence from nearly 200 sites across 33 countries points to which approach delivers sustainable competitive advantage.
