A workflow bottleneck occurs when a specific step in a process restricts the overall speed of the workflow. Even if other parts of the process operate efficiently, work cannot move faster than the slowest or most constrained step.
Bottlenecks often form when too many tasks depend on a single decision point, system, or individual. This creates a buildup of work waiting to move forward, which increases delays and reduces overall throughput.
Common causes include approval requirements that concentrate decisions with a small number of people, reliance on specialized knowledge held by one individual, overloaded or outdated systems, and unclear ownership of decisions or next steps.
Over time, bottlenecks can slow the entire workflow, increase cycle times, and create downstream issues such as rework, missed deadlines, or excessive coordination between teams trying to move work forward.
Identifying bottlenecks is often one of the first outcomes of a workflow diagnostic. Once identified, these constraints can be redesigned, redistributed, or removed to improve flow and increase overall efficiency.
