How can you use Control Charts for Kanban metrics?

A control chart is like a quality control dashboard, visualizing a process's stability over time. Center lines and control limits show the expected range of variation. Data points falling outside those limits signal potential issues needing investigation. Imagine a control chart as a watchful eagle scanning your process, highlighting red flags in the form of data points straying beyond safe zones. With different types for diverse data, be it temperature averages or defect rates, these charts empower you to diagnose problems early, nip inefficiencies in the bud, and ensure consistent quality From preventing defects to optimizing settings, control charts help improve quality, efficiency, and customer satisfaction

In Six Sigma, a control chart is a graphical tool used to monitor a process over time and determine whether it is within control or out of control. It helps in identifying and addressing variations or abnormalities in a process before they result in defects or errors.

Control Charts play a crucial role in Kanban as they enable the monitoring and enhancement of workflow. Here are some examples: 1. **Cycle Time Control Chart:** This chart allows for the tracking of the time it takes for tasks to progress through the Kanban system. By ensuring consistent and predictable delivery times, it helps maintain efficiency. 2. **WIP (Work in Progress) Control Chart:** By monitoring the number of tasks in progress at any given time, this chart aids in optimizing workflow and preventing bottlenecks. It provides valuable insights into task distribution and resource allocation.

Control chartes primarily visualize process variability, which can help us understand the predictability of our process to produce VALUE for our customers. Control charts can help in Following different Kanban metrics - 1. WIP in the system - with active, inprogress stages within the Kanban system. It also helps to monitor WIP to balance the workload and flow in the system. 2. Cycle time - Helps visualize the variability, allowing more precise planning and effective resource allocation. With this we can make adjustments in upstream or downstream processes. 3. Throughput - track overall productivity levels over time especially on bottlenecks.

Control charts in Kanban help monitor process stability and variation. Utilize them to track key metrics like cycle time or lead time regularly. Plot data points representing these metrics over time on the chart. Establish upper and lower control limits based on historical data. Analyze if data points fall within these limits; if not, investigate for potential issues. Control charts aid in identifying deviations, allowing timely interventions to maintain process efficiency in Kanban systems.

Applying control charts for Kanban metrics enable the team to autonomously take actions when things are out of control. A control chart is effective when it is paired with an Out of Control Action Plan (OCAP).

Control charts are traditionally used in Kanban to monitor process stability and identify variations. For an unconventional use, you might leverage a control chart to manage team workload by plotting the number of tasks in progress against the team's average capacity. This way, you can visualize bottlenecks or underutilization and adjust assignments accordingly to ensure a steady workflow and prevent burnout or idle time.

Below are other charts which used in Kanban Metrics: 1) Burndown Chart - this is most important metrics that project manager using Kanban should track. It’s shows number of tasks planned and completed. Also predicts future performance. 2)Lead & Cycle time chart- Here you can check average number of days that task took during specific time. It’s help to check efficiency, bottlenecks and speed of completion 3) Cumulative Flow chart: It’s help to assess the overall success of projects. It’s shows the completed assignments, what is current task going on and the task which is waiting to get started. Apart from this there is WIP, Team performances , bottlenecks and time tracking is important part of this

We use Cumulative Flow Diagram (CFD) to track the cumulative number of work items in each stage of the workflow over time. CFD provides insights into the flow of work and helps identify bottlenecks or areas of congestion in the process. Lead Time Distribution Chart displays the distribution of lead times for completing work items. It helps teams understand the variability in lead times and identify trends or patterns that may impact process efficiency. Control charts, such as the XmR chart, monitor process stability and detect any shifts or trends in performance metrics over time. They help distinguish between common cause variation (inherent to the process) and special cause variation (resulting from external factors or process changes).

If a Kanban team has elements of Scrum, it can be useful to track velocity as a metric for process improvements. Velocity helps in planning and forecasting future sprints based on past performance. By using control charts for team velocity, Agile teams can identify the velocity of each sprint over time, calculate the average velocity for a certain number of sprints, deviations from the average. It could be interesting to analyse trends in data. For example, increase in velocity can be an indicator of process improvements, and a decrease can be an indicator of complexity or lack of resources

In my previous work, rejects per hour was the monitored metric. This was calculated from data gathered during preproduction. It was a control where if the amount of rejects generated by a certain process exceeded the set limits, the line would be forced to stop while the reject cause was investigated then corrected. In machines like the heat press, tool temperature would be measured at the start of shift, then plotted on a graph. If any trends showed, or if it exceeded the control limits, the machine would be investigated and the issue solved before a more serious breakdown occurred.

Examining lead times for both internal and external customers, the impact of Kaizens, and the performance of capacity utilization are crucial factors for utilizing control charts. You can track the metrics of both Kanban and the success of ongoing continuous improvement studies.

Control charts are typically used in statistical process control (SPC) to monitor & control processes over time. KANBAN, on the other hand, is a visual management method for controlling work & inventory levels in a just-in-time (JIT) production system. While control charts & KANBAN serve different purposes, there can be situations where they complement each other, especially in a manufacturing or production environment. Control charts can complement KANBAN by providing a quantitative, data-driven way to monitor and improve processes related to KANBAN metrics. They help you detect variations, set appropriate limits, and ensure the stability and efficiency of your KANBAN system.

Besides cycle time, apply control charts to other Kanban metrics like throughput, work in progress, lead time, or defect rate. Each metric can provide unique insights into different aspects of the workflow. Utilize the control chart to identify trends, patterns, and anomalies in cycle times or other metrics. Investigating these can reveal underlying process issues or areas for improvement. Incorporate the analysis of control charts into regular team meetings or reviews. Discussing these insights as a team fosters a collective understanding and approach to process improvements.
