Bottleneck Analysis

Turns workflows, data, causes, and improvements into a tangible result by mapping the process flow, measuring waiting time and WIP, and re-evaluating the bottleneck after changes.

Core question
Where does work accumulate in the process, which step limits overall throughput, and which escalation level, utilization, subordination, or elevation, is the next effective move?
MediumWorkshop + async1-3 h
Purpose

The method helps clarify workflows, data, causes, and improvements in a concrete way. It looks for patterns, causes, weak spots, or bottlenecks and derives actions. The result is captured as a bottleneck map, flow metrics, and improvement options.

How it works

The team follows the steps: map the process flow, measure waiting time and WIP, identify the bottleneck, develop relief options, and check the impact while re-evaluating the bottleneck. Each step is captured visibly. At the end, a bottleneck map, flow metrics, and improvement options are available so decisions, tests, or actions can follow directly.

Ideal for

  • Throughput problems
  • Kanban and delivery processes
  • Operational overload

Not good for

  • One-off tasks
  • Problems without process flow
  • Pure root-cause analysis without flow data

Deep dive

In detail

Bottleneck Analysis sees a system as a chain whose performance is set by the slowest or most constrained point. The method looks for queueing, waiting, high utilization, and growing work in progress. Once the bottleneck is identified, measures are aimed at protecting it, relieving it, or increasing capacity. After that, the team checks whether the bottleneck has moved.

Facilitation

Collect data on waiting time, throughput, utilization, and inventory. Visualize the flow and ask where work regularly gets stuck. Avoid measures at convenient but non-constraining points and verify the new system bottleneck after changes.
