Definition: Bottleneck

Bottleneck is a term that means a resource or an entity in a chain that might prove to be the bone of contention in a process. It is actually an important cog in the process and hence, it is vital in the completion of the process.

It is like a constraint that takes the longest time in the process. We can explain the bottleneck with the help of a real life example. A company needs to enter a foreign market but the criteria for entering requires a certain NOC, which is difficult to obtain, and requires certain budget. This creates a bottleneck for that company to enter the foreign market.

Issues arising due to bottlenecks

The major issues arising due to bottlenecks are:

1. Lower throughput

2. Increased waiting times

3. Excessive inventory leading to higher operation cost


Prevention of bottlenecks is essential because they can help in optimizing a process and can ensure that it gets done in the shortest time frame. As we know that time is at premium in a supply-chain process, hence bottlenecks must either be prevented or circumvented.

The flow diagram exhibits how can it be done:


There is a theory known as the Theory of Constraints (TOC) that gives the various ways by which one can identify bottlenecks in a supply-chain. Some of the ways are:

1. Accumulation

2. Throughput

3. Wait times

4. Fishbone diagram
