Metaphorically a bottleneck is a section of a route with a carrying capacity substantially below that characterising other sections of the same route. This is often a narrow part of a road, perhaps also with a smaller number of lanes, or a reduction of the number of tracks of a railway line. It may be due to a narrow bridge or tunnel, a deep cutting or narrow embankment, or work in progress on part of the road or railway. Capacity bottlenecks may occur at sea ports and places like the Panama Canal. In language, a metaphor (from the Greek: metapherin) is a rhetorical trope defined as a direct comparison between two seemingly unrelated subjects. ...

More generally, a bottleneck is one process in a chain of processes, such that its limited capacity reduces the capacity of the whole chain. A related concept is critical path (see Project Management) and the Theory of Constraints (see Industrial Engineering and Operations Management). In project management, a critical path is the sequence of project network terminal elements with the longest overall duration, determining the shortest time to complete the project. ... Project management is the discipline of defining and achieving targets while optimizing the use of resources (time, money, people, materials, energy, space, etc). ... Theory of constraints (TOC) is a body of knowledge on the effective management of (mainly business) organizations, as systems. ... Industrial engineering is the engineering discipline that concerns the design, development, improvement, implementation and evaluation of integrated systems of people, knowledge, equipment, energy, material and process. ...


In computer science, some authors refer to the von Neumann bottleneck between processor and memory. Bottlenecks may arise in communication networks, thereby disrupting throughput. Computer science - Wikipedia, the free encyclopedia /**/ @import /skins-1. ... The so-called von Neumann architecture is a model for a computing machine that uses a single storage structure to hold both the set of instructions on how to perform the computation and the data required or generated by the computation. ... // Communication is the process of exchanging information, usually via a common system of symbols. ... A wide variety of systems of interconnected components are called networks. ...


Bottleneck is also a common term for slide guitar, because the broken-off neck of a bottle was and is often used to play that style of guitar. This musical form is most popular among Blues guitarists but is also found in some country and rock playing. This article needs a complete rewrite for the reasons listed on the talk page. ...


In a Surface Mount Technology (SMT) Board Assembly Line with several equipments aligned, usually the common sense is driven to set up and shift the bottleneck element towards the end of the process, inducing the better and faster machines to always keep the PCB supply flowing up, never allowing the slower one's full stop, a fact that would be heeded as a deleterious and significant overall drawback on the process.
