In production and project management, a bottleneck is a process in a chain of processes, such that its limited capacity reduces the capacity of the whole chain. The result of having a bottleneck are stalls in production, supply overstock, pressure from customers, and low employee morale. [1] There are both short and long-term bottlenecks.
In engineering, a bottleneck is a phenomenon by which the performance or capacity of an entire system is severely limited by a single component. The component is sometimes called a bottleneck point. The term is metaphorically derived from the neck of a bottle, where the flow speed of the liquid is limited by its neck.
In streamline manufacturing, the bottleneck is the station of a production line where greatest limiting factor lies. It is generally the station with the greatest amount of work in process at the work station. Bottlenecks often results in slow production times, surplus of raw material and low employee morale.

The Shifting Bottleneck Heuristic is a procedure intended to minimize the time it takes to do work, or specifically, the makespan in a job shop. The makespan is defined as the amount of time, from start to finish, to complete a set of multi-machine jobs where machine order is pre-set for each job.
A system or application will hit a bottleneck if the work arrives at a comparatively faster pace relative to other processing components. [3] According to the theory of constraints , improving on the occurrences of hot-spot point of the bottleneck constraint improves the overall processing speed of the software. [ 4 ]
The term "bottleneck" is explained by a common type of application of the problem, where the cost is the duration of the task performed by an agent. In this setting the "maximum cost" is "maximum duration", which is the bottleneck for the schedule of the overall job, to be minimized.
In such context, a bottleneck link for a given data flow is a link that is fully utilized (is saturated) and of all the flows sharing this link, the given data flow achieves maximum data rate network-wide. [1] Note that this definition is substantially different from a common meaning of a bottleneck. Also note, that this definition does not ...
