Cycle Time

Cycle Time is a performance metric that measures the time it takes to complete a single work item or task from the moment it enters an active, work-in-progress state until it reaches completion. It is a key concept in Lean, Agile, and Kanban methodologies and is used to assess the efficiency and effectiveness of a team’s workflow.

Key points about Cycle Time include:

  1. Focus on Active Work: Cycle Time specifically measures the time taken for active work on a task or work item. It does not consider waiting or idle time in queues before the work starts.
  2. Individual Work Items: Cycle Time is calculated on a per-task or per-work item basis. It provides insights into the lead time for individual tasks within the workflow.
  3. Continuous Flow: Cycle Time aligns with the principles of continuous flow, where work items are completed and delivered in a steady, ongoing manner.
  4. Predictability: By analyzing historical Cycle Time data, teams can establish a predictable flow of work and estimate how long similar tasks might take in the future.
  5. Process Efficiency: Shorter Cycle Times often indicate higher process efficiency, as work items are completed more rapidly and move through the workflow smoothly.
  6. Variability: Cycle Time can vary depending on the type, complexity, and size of work items. Understanding this variability can help teams set appropriate expectations and identify potential areas for improvement.
  7. Cycle Time vs. Lead Time: Cycle Time is a component of Lead Time. While Cycle Time focuses on active work, Lead Time includes the time spent waiting in queues or in the backlog before work begins.

Cycle Time is typically measured using the following steps:

  1. Start the Timer: When a work item or task is actively picked up by a team member and work begins, start the timer.
  2. Stop the Timer: When the work item is complete and ready for delivery or deployment, stop the timer.
  3. Record the Time: Calculate the time elapsed between starting and stopping the timer to determine the Cycle Time for that specific task.
  4. Analyze and Improve: Collect and analyze Cycle Time data to identify patterns, areas for improvement, and opportunities to optimize the workflow.

Cycle Time is a valuable metric for teams practicing Agile, Kanban, or other iterative approaches to software development or project management. It provides teams with insights into their productivity, helps identify potential bottlenecks, and supports continuous improvement efforts to enhance overall workflow efficiency. Additionally, shorter Cycle Times contribute to faster delivery of value, increased customer satisfaction, and more predictable project outcomes.
