The Theory of Constraints (TOC) is a framework of interdisciplinary knowledge, methods, and management tools for organizations. It starts from the premise that imbalance is inevitable but also desirable. The flow management method of the Theory of Constraints, called Drum – Buffer – Rope, involves pacing the release of manufacturing orders to the pace of the bottleneck to avoid excess work in progress and reduce cycle times, while ensuring that parts arrive sufficiently early to never stop the same bottleneck. The five key implementation steps of the theory of constraints are: 1, identify the constraint; 2, exploit the constraint (increase its utilization and efficiency); 3, subordinate all processes to the constrained process; 4, elevate the performance of the constraint (if necessary); 5, repeat from step 1.

Almost 10 years after a Qeqertarsuatsiaat that opened up vast acoustic spaces for them, and after more electric and even sporty explorations, Jérémie Ternoy, Ivann Cruz, and Peter Orins return with their drums, buffers, and ropes to play the tightrope walkers on their instant constraint flows, always seeking compulsive stubbornness and sonic stacking.
