Kitsenduste

Kitsenduste is the Estonian term for bottlenecks or constrictions that limit performance in a system. The plural/genitive form "kitsenduste" is used when referring to multiple such constrictions. The concept spans several fields, including engineering, information technology, economics, logistics, and biology, where a single constriction can determine overall throughput.

In practice, identifying kitsenduste involves examining flow, capacity, and demand. Common indicators include rising wait times, high resource utilization around a point, or disproportionate cycle times. Techniques such as bottleneck analysis, queueing theory, and throughput modeling are employed to locate the constrictions.

In manufacturing and supply chains, a system's throughput is limited by the slowest operation; in software, a service or database layer with limited parallelism can become a bottleneck. In biology or medicine, stenosis of vessels or ducts can act as bottlenecks, restricting flow and causing symptoms.

Mitigation strategies include redistributing work, adding capacity at the bottleneck, removing non-value-adding steps, or rearchitecting the process to parallelize work. The Theory of Constraints (TOC) places emphasis on identifying the bottleneck and elevating its performance before addressing other steps.

Etymology and usage: In Estonian, kitsendus denotes constriction or bottleneck, and kitsenduste is its plural/genitive form used in formal writing to describe multiple such constraints.
