Establishing a stable workflow is the key to building successful and productive teams. A stable workflow helps your organization deliver faster to market and brings greater value to your customers and organization.
But how can you measure the success rate of your workflow and improve it?
The answer is simple - by using statistically significant data. This is why most of the contemporary online Kanban solutions are equipped with powerful analytics modules, that provide you with valuable workflow data. Using Kanban metrics is necessary for understanding how your team is performing and where they need to improve.
With Kanban flow metrics, you don’t need to guess when work on a project will be done. The metrics of your workflow will give you hard data on the productivity, efficiency, and reliability of your production process.
Here is why you can consider these as team productivity metrics and process efficiency metrics.
Now, let’s discover which are the best Kanban reporting metrics that you need to know.
Lead Time and Cycle Time
Lead time and Cycle time are two of the most important and useful Kanban metrics. They can help you understand how long work items spend in your workflow until they are completed. Lead time is the total amount of time a task spends from order to delivery in your system. Cycle time is the amount of time you spend actively working on it.
People, often confuse these two, but there is a clear difference.
Basically, lead time starts from the moment a new task is requested and ends when it is done. On the other hand, cycle begins when someone actually starts working on a given assignment. In other words, cycle time starts from the commitment point.
Both metrics are very important, because they can show you how long it takes for work to flow through your value stream.
You can use lead time metrics to analyse if work items wait for too long before they enter in progress.
On the other hand, cycle time metrics help you understand the amount of time needed for the actual completion of a given task.
How to measure Cycle time and Lead time?
In order to measure the average cycle and lead time you can use a Cumulative Flow Diagram - one of the most advanced data sources for your workflow. The CFD can show you the average cycle time and lead time as well as the number of work in progress items. This way you can see how stable your workflow is and where you need to improve.

If you want to analyze the cycle time of individual work items you can use the Cycle Time Scatter Plot. It will help you spot tasks that took a greater amount of time to be completed. It will help you discover and analyze possible reasons that slows down the work process.

Additionally, you can also use the Cycle Time Histogram in order to see the most common cycle time length for your work tasks. This tool will help you monitor and control the desired pace of your team.

Throughput is the number of tasks finished per time unit. For example, completed work items per day. Throughput can be named a team productivity metric. It represents the productivity level of your team in the past.
The throughput is an important metric to track, because this way you can acquire a better understanding of the impact that your workflow has on the total business performance. The overview of total processed units can help you take important business decisions, such as to expand work capacity, to speed up production and so on.
The throughput is a tricky metric.It shows you the number of tasks that have been finished per day. However, it doesn’t show you when different tasks were started. This is why for more precise future decisions you can combine the throughput metrics with cycle time and lead time.
How to measure Throughput?
You can use the Throughput Histogram in order to see number of days that had a certain throughput or what percentage of all days had a certain throughput. It will give you a better understanding of your team’s capacity.

Work in Progress
Basically, unfinished work that is in progress cannot add value to your customers. However, it plays crucial role when you want to monitor and analyze your workflow’s capacity. This is why it is important to track work items that are in progress, but not finished yet. By doing so, not only can you determine your team’s capacity, but you can also improve the value flow.
You can easily monitor work in progress on your Kanban board. The board shows you a quick overview of all tasks that are in progress and vital information related to each task, such as assignee, deadline, description and so on.
How to measure Work in Progress?
Furthermore, by using an Aging Work in Progress chart, you can see the sum of all work items that are being processed and how much time has passed since they were started. This way you can spot tasks that have been in progress for too long and why.

Queues (The Cost of Waiting)
Queues appear in your workflow while tasks await further action. For example, a queue stage can be ”waiting for review”. Actually, queues accumulate a major part of tasks’ cycle time, because work items are often interrelated and they depend on different team members. This is why it is important to track queues and understand how they can impact your overall performance. It is reasonable to limit the number of work items that are in queues and try to move them as fast as possible.
In Lean, waiting is considered a major waste. Therefore, the longer tasks spend in queues, the higher the costs.
How to track and analyze Queues?
You can use the Heat Map to monitor and analyze queues. This tool actually shows how long your tasks have spent in each stage of your workflow. This way you can see the total amount of time work items spent in queues during a predefined time frame.
When Will It Be Done?Wouldn’t be great if your business can answer this question with certainty? Of course it would. Work estimation has always been a problem, but now you can use data-driven forecasts in order to see when your tasks will be completed. Meet Monte Carlo simulations - a statistical tool that can help you make data-driven decisions. Based on your workflow’s historical data this tool runs through a large number of random simulations to give you a probabilistic forecast when current tasks can be finished or how many tasks can be completed for a certain period of time.
