A systematic method for identifying and analyzing constraints that limit system performance or process flow.

Bottleneck Analysis

Bottleneck analysis is a critical methodology in systems thinking used to identify and address points of congestion or constraint that limit the overall performance of a system, process, or operation.

Core Concepts

Definition and Characteristics

A bottleneck represents the point in a system where:

Flow capacity is most restricted
Work accumulates or queues form
Overall system throughput is limited
Resources experience highest utilization

Types of Bottlenecks

Static Bottlenecks
- Fixed constraints that consistently limit system performance
- Often related to physical constraints or infrastructure limitations
- Example: Machine processing capacity in manufacturing
Dynamic Bottlenecks
- Temporary or shifting constraints
- Can move between different process steps
- Influenced by variability and system conditions
