Do You Measure Kanban Throughput? – Aditi Agawal


What is Kanban throughput? What’s the very best method to determine it? This short article reviews these concerns and offers a point of view to track a Kanban group’s efficiency in an efficient method.

What Is Kanban Throughput?

Kanban Throughput is specified as the typical variety of products or cards going through the circulation within a particular time period supplied that the workload remains uniform throughout that duration. It is normally utilized to track group’s efficiency. Throughput irregularity shows the distinction in size, intricacy, and group abilities.

According to the Little’s Law:

Throughput = Overall WIP/ Typical Preparation

Determining What Matters: Kanban Throughput

The very best method to determine throughput in Kanban is with the CFD (Commulative Circulation Diagram). The Cumulative Circulation Diagram is the graph of the cards as they move from one column or state to another on a Kanban board. The CFD plots the variety of cards at each phase at an offered time.

Below is a sample CFD for your recommendation:

The various colors on this diagram represent the numerous states in the circulation. The height of each color band shows the variety of cards because state at that point in time.

The CFD offers you with an insight on the number of cards moved from one state to another in a particular time period. Usually, the CFD is outlined for each day, nevertheless, if there are a lot of moving cards in a day, it can be outlined on a per hour basis too. Below is a sample CFD when outlined for each hour in a working day.

Additionally, the CFD offers important information on preparation and cycle time patterns. Both lead time and cycle time signify the time a work product invests in the workflow up until they are total. Preparation is the time that a card draws from start to end up. Cycle time is the time an engineer invests to actively deal with it. In a CFD, both preparation and cycle time metrics are determined along the horizontal axis

The Cumulative Circulation Diagram (CFD) likewise shows overall cards throughout various columns i.e. overall WIP. This information is determined along the vertical axis of the CFD diagram.

Below is a sample CFD that portrays preparation, typical cycle time, and the overall WIP.
