Process Power
Evolve processes so complex and tacit that competitors cannot replicate them in time
Process Power exists when embedded company organization and activity sets enable lower costs or superior product, and can be matched only by an extended commitment. This is the rarest of the seven Powers because while the Benefit -- evolutionary bottom-up improvement -- is extremely common (it is the heart of operational excellence), the Barrier -- an unyielding long-time constant that prevents competitors from replicating improvements regardless of investment -- is exceedingly rare.
Helmer agrees strongly with Michael Porter's assertion that operational excellence is not strategy. The vast majority of process improvements can be mimicked by capable competitors through normal competitive arbitrage. Process Power exists only in those rare cases where two conditions create hysteresis: Complexity (the process touches so many interconnected parts that reproducing it quickly is impossible) and Opacity (the knowledge is tacit rather than explicit, developed bottom-up through decades of trial and error, and not fully understood even by the company that created it).
The Toyota Production System is Helmer's central example. Despite full transparency -- Toyota welcomed hundreds of thousands of executives to tour their plants -- GM could not replicate TPS results even through the NUMMI joint venture. Toyota's manager at NUMMI explained: 'I think they recognized we were asking all the wrong questions.' The TPS was not a set of copyable procedures but an emergent system so deeply embedded that even Toyota took fifteen years to transfer it to their own suppliers.
- Process Power = operational excellence + hysteresis (an inherent speed limit on replication)
- The Benefit (bottom-up process improvement) is common; the Barrier (hysteresis preventing replication) is extraordinarily rare
- Two factors create hysteresis: Complexity (many interconnected process touchpoints) and Opacity (tacit knowledge that cannot be fully articulated or documented)
- Process Power becomes available only in the stability stage because it requires decades of sustained evolutionary advance
- The Experience Curve shows that improvements over time are common, but tells nothing about relative position between firms -- it testifies to the ubiquity of competitive arbitrage, not to Power
- Even full transparency does not break Process Power -- Toyota opened its plants to visitors and still could not be copied
- Commit to decades of bottom-up evolutionary process improvementProcess Power cannot be designed top-down or achieved through a single initiative. Toyota spent from 1950 to 1980 developing TPS before its effects became dramatically visible in market share. Embed continuous improvement into your organization's culture and sustain it through leadership transitions, market cycles, and competitive pressures.
- Develop processes that span the full complexity of your value chainTPS was not just about assembly line procedures. It encompassed the entire supply chain backward to suppliers and forward through distribution. The complexity of these interconnections is what creates hysteresis. GM's NUMMI manager realized too late: 'All of our questions were focused on the floor. That's not the real issue. The issue is how you support that system with all the other functions.'
- Allow tacit knowledge to accumulate rather than forcing premature codificationThe opacity of TPS was essential to its inimitability. The system was fashioned bottom-up through decades of trial and error, never formally codified, with much organizational knowledge remaining tacit. Do not assume that documenting every process in a manual makes it transferable. The most valuable process knowledge is often embodied in organizational routines that resist articulation.
- Test whether your process advantages have genuine hysteresisAsk: if a well-funded, motivated competitor studied our processes with full access, could they replicate the results within 3-5 years? If yes, you have operational excellence but not Process Power. GM had full access to TPS through NUMMI and could not replicate it in their other plants over decades. That is genuine hysteresis.
From Eiji Toyoda's 1950 Ford plant visit, Toyota spent decades evolving TPS through bottom-up trial and error. The system's surface techniques -- just-in-time, kaizen, kanban, andon cords -- appeared straightforward. But they manifested a deeper system of such complexity and tacit knowledge that replication proved impossible. GM's 1984 NUMMI joint venture achieved Toyota-quality results at one plant, but despite Toyota's full transparency, GM could not transfer the practices to any of its other facilities. Harvard Business Review noted that 'few manufacturers have managed to imitate Toyota successfully even though the company has been extraordinarily open about its practices.'
Helmer traces the Toyota Production System from Eiji Toyoda's 1950 visit to Ford's River Rouge Plant, where he was unimpressed by wasteful deep inventories but inspired by American supermarket restocking practices. Over decades, Toyota developed what became TPS -- just-in-time production, kaizen, kanban, andon cords -- bit by bit through evolutionary bottom-up refinement. From a 0.1% US market share in 1969, Toyota pulled nearly even with GM and Ford by 2014. GM's desperate attempt to replicate TPS through the NUMMI joint venture succeeded in producing high-quality cars at one plant but failed utterly to transfer the knowledge to GM's other facilities.
