Greater Waste Elimination vs. Preserved Process Resilience
Business Context. Lean's focus on eliminating waste often targets buffers, slack capacity, and redundant steps as non-value-adding, but removing too much buffer can leave a process fragile and unable to absorb unexpected disruption.
Process TRIZ Resolution. Rather than eliminating all buffers indiscriminately, organizations should distinguish genuinely wasteful excess from strategically placed resilience buffers, removing the former while deliberately preserving the latter at critical points in the process.
Applicable TRIZ Principles
Principle 3 (Local Quality) distinguishes wasteful excess from deliberate resilience buffers.
Principle 11 (Beforehand Cushioning) preserves strategic buffers at points where disruption risk is highest.
Principle 2 (Taking Out) removes only the excess that does not serve a resilience purpose.
Expected Outcome
Reduced genuine waste
Preserved operational resilience
Lower risk of disruption-driven failure
Sustainable lean operations
Decision Indicators
Lean initiatives have removed all buffers regardless of their purpose.
Minor disruptions now cause disproportionate process failures.
No distinction is made between wasteful excess and strategic buffer.
Resilience has declined noticeably since the last lean initiative.
Teams cannot absorb even small volume spikes without failure.
If several of these indicators are present, the contradiction is likely active and the Process TRIZ resolution above should be evaluated.
