- Industry 4.0 in discrete manufacturing could unlock about US$3.7 trillion by 2025, but only ~30% of companies are capturing value at scale.
- McKinsey segments factories into small-lot, mass-customized, and high-volume archetypes, each with distinct value drivers and use-case priorities.
- Scaling beyond pilots requires a value-first roadmap, strong leadership and capability building, and a modular IT/OT and data infrastructure with a clear target picture.
- Market tailwinds remain strong, with Industry 4.0 spend projected to rise from roughly US$655B in 2025 to about US$1.6T by 2030 (~19% CAGR).

The McKinsey report “Capturing value at scale in discrete manufacturing with Industry 4.0” (September 2019) remains foundational in understanding how discrete manufacturers can move from pilot experiments to scaled transformations. Key insights remain broadly validated by more recent market data.
Value Potential vs. Realization Gap. McKinsey estimates that discrete manufacturing could generate US$3.7 trillion of combined value by 2025 for manufacturers and suppliers, yet only ~30 percent of companies are actually capturing these benefits at scale. This suggests a large latent gap—most firms have pilots or point initiatives, but scaling remains elusive.
Factory Archetypes and Specific Value Drivers. The report categorizes factories along two dimensions—variant count and lot size—leading to three archetypes: ‒ small-lot manufacturing (variation high, lot size low) ‒ mass-customized production (moderate variation, medium to high throughput) ‒ high-volume production (low variation, large lot sizes). Each archetype faces different pressures: for small-lot, flexibility and craftsmanship; for mass-customized, throughput + quality + agility; for high-volume, automated efficiency, OEE, and traceability.
Scaling Mechanisms. McKinsey recommends three strategic principles to escape pilot purgatory: (i) reverse the logic to focus on value first rather than leading with technology; (ii) adopt people-centric transformation—capability building, leadership commitment, and organizational anchoring; (iii) build an infrastructure (IT/OT, data model, modular automation) with a clear target picture and enabling for local before global rollout.
Recent Market Trends. More recent data from 2024–2025 confirms accelerated demand and spending: the global Industry 4.0 technologies market is forecasted to grow from ~US$655.2 billion in 2025 to ~US$1.6 trillion in 2030, implying a ~19.4 percent CAGR. Additional analysis estimates that full-sector digital transformation could deliver returns to shareholders worth US$0.8–2 trillion over time in existing industrial companies, driven by revenue growth (new services, better customer insights) and margin expansion (automation, efficiency).
Strategic Implications.
- Leaders should perform “network scans” to find high-value use cases and critical factories that represent major portions of value. McKinsey found in some cases just a handful of sites represent ~80 percent of opportunity and that 10 out of ~17 use cases represent ~75 percent of impact [0search0].
- Investment needs to be pushed into skills and change‐management to enable scaling; top management must own the transformation, avoid tool benchmarking, and ensure clear governance.
- Infrastructure design must balance local (factory‐level) flexibility and global (network) standards—modular IT/OT stacks, integrated product data models, traceability systems, closed-loop quality control etc., become foundational assets.
- Market tailwinds (automation cost decline, robotics, AI capabilities, sustainability pressure, supply chain demands) amplify the urgency; firms that fall behind risk losing competitive positioning.
Open Questions & Risks.
- How will sustainability, supply chain shocks, and geopolitical reshoring affect the archetypes’ viability, especially for high-volume and mass-customized producers?
- What level of investment in cybersecurity, data privacy, and standards harmonization will be needed to ensure scalable, secure operations?
- How to address the skill gap, especially with temporary, contract, or low-skilled labor in small-lot and high-variance settings?
- Return horizons vs. capital intensity: can firms sustain long implementation periods before hitting scaled value?
Supporting Notes
- McKinsey projects US$3.7 trillion of value in 2025 for manufacturers and suppliers via Industry 4.0, yet only about 30 percent of companies are capturing value at scale today due to hurdles like unclear value focus and scaling difficulties.
- The factory archetypes—small-lot, mass-customized, high-volume—are differentiated by variant count and lot size; each archetype has specific key drivers like product data models, automation, or closed quality loops.
- Machinery (small-lot): value through digital enablement of workers, integrated product data, OEE optimization especially for heavy internal machining.
- Automotive (mass-customized): value through flexible routing/scheduling, in-line sensor quality control loops, and automation including co-bots for final assembly.
- Consumer electronics (high-volume): key drivers include automation in final/preassembly, closed control quality loops, component and product traceability for yields, waste, sustainability.
- Scaling requires three principles: think value backward (value‐first vision), people centric (skills, leadership), innovate infrastructure (modular, local scalable globally).
- Market projections: global Industry 4.0 technologies market value forecasted to grow from ~US$655 billion in 2025 to ~US$1.6 trillion by 2030; CAGR ~19.4 percent.
- Analysis of industrial sector suggests transformations across product, delivery, and operations could yield shareholder returns in the range of US$0.8-2 trillion via revenue growth (3-10 percent) and margin expansion (4-9 percent).
