What is Bottleneck Analysis?

Bottleneck analysis is a systematic approach to identifying the constraint points in your operational workflow that limit the overall throughput of the system. A bottleneck is any step or resource whose capacity is less than the demand placed on it, causing work to queue up and downstream processes to sit idle. In e-commerce operations, bottlenecks commonly occur at picking, packing, quality check, or carrier pickup stages.

Why It Matters

The throughput of your entire fulfillment operation is determined by its bottleneck. Optimizing any other step without addressing the bottleneck will not increase overall output—it will only build up more work-in-progress at the constraint point. Identifying and resolving bottlenecks is the most efficient way to increase capacity and reduce order cycle times without proportionally increasing headcount or equipment.

How It Works

• Identification: Look for where work queues up. The step with the longest queue or wait time before it is likely the bottleneck. In a warehouse, if packing stations have piles of picked orders waiting while picking carts are empty, packing is the bottleneck.
• Measurement: Quantify the capacity of each step: orders per hour at picking, packing, labeling, and loading. The step with the lowest capacity is the constraint.
• Resolution: Address the bottleneck through staffing (add packers), process improvement (simplify packing), technology (automated label application), or layout optimization (reduce walking distance).
• Iteration: Once you resolve one bottleneck, a new one will emerge at the next weakest link. Continuous improvement means continuously finding and fixing the current bottleneck.

How Nventory Helps

Nventory provides operational analytics that track throughput at each stage of the fulfillment pipeline, highlighting bottlenecks in real time. The system shows where orders are queuing, how long they spend at each stage, and which steps are limiting overall throughput—giving you the data needed to make targeted improvements.
