Harnessing Flow Metrics to Enhance Scrum Practices


Scrum and Kanban are often seen as competing approaches in agile working methods. This blog post will explore how flow metrics can enhance Scrum practices, busting the myth that Scrum and Kanban are legendary enemies.

Understanding Flow Metrics

Flow metrics are performance indicators that help teams understand and improve workflow through their processes. Some essential flow metrics include cycle time, throughput, and work-in-progress (WIP) limits.

Cycle Time

Cycle time represents the total time for a work item to move from start to completion. By measuring cycle time, teams gain insights into the efficiency of their processes, identify bottlenecks, and make data-driven decisions to optimise workflow.


Throughput measures the rate at which work items are completed over a given period. It provides an understanding of a team’s capacity to deliver value. Tracking throughput enables teams to improve forecasting, plan future sprints, and assess the impact of process changes.

Work in Progress (WIP) Limits

 WIP limits help control the work in progress at any given time. By setting WIP limits for each workflow stage, teams prevent overloading, reduce context switching, and maintain focus. In addition, WIP limits create a visual signal that prompts teams to collaborate, prioritise, and complete work before starting new tasks.

Applying Flow Metrics in Scrum

Integrating flow metrics into Scrum practices can significantly enhance a team’s effectiveness and self-management. Here’s how:

  1. Optimising Cycle Time: By measuring cycle time, Scrum teams can identify bottlenecks and areas of improvement. Through continuous refinement, they can streamline processes, remove impediments, and reduce cycle time, leading to faster delivery and improved customer satisfaction.
  2. Forecasting and Capacity Planning: Throughput metrics enable Scrum teams to forecast how much to pull from the backlog items. By understanding their throughput trends, teams can make more reasonable capacity plans in sprints, ensuring a realistic allocation of work and avoiding over-commitment.
  3. Managing WIP: While Scrum focuses on delivering increments of value within sprints, incorporating WIP limits from Kanban helps maintain a balanced workload. Setting appropriate WIP limits for each stage of the Scrum workflow prevents work bottlenecks, reduces multitasking, and fosters a smoother flow of tasks.
  4. Continuous Improvement: Flow metrics provide objective data for retrospectives and constant improvement. For example, Teams can use cycle time and throughput data to identify patterns, experiment with process changes, and assess the effectiveness of their adaptations. This data-driven approach fosters a culture of continuous learning and innovation within the Scrum framework.


The belief that Scrum and Kanban are legendary enemies fails to recognise the complementary nature of their practices. By incorporating flow metrics into Scrum, teams can harness the power of data-driven decision-making, enhanced efficiency, and continuous improvement. Flow metrics such as cycle time, throughput, and WIP limits enable Scrum teams to optimise their processes, forecast better, and manage workloads effectively. Furthermore, by leveraging flow metrics within the Scrum framework, teams can enhance their agility, predictability, and overall success. So, rather than pitting Scrum against Kanban, let’s embrace the best of both worlds to tailor an agile approach that fits our context.
