Cycle Time
Cycle Time
Cycle Time is an important Agile metric that measures how long it takes a team to complete a piece of work after they begin actively working on it.
Unlike Lead Time, which measures the total time from customer request to delivery, Cycle Time focuses only on the period when the team is actively working on the task.
Cycle Time helps Agile teams understand their efficiency, identify bottlenecks, and improve the speed of delivering work.
Definition of Cycle Time
Cycle Time is the amount of time between the moment work starts on a task and the moment that task is completed and delivered.
Cycle Time measures how long it takes to complete work once development has started.
Cycle Time Formula
The result is typically measured in hours, days, or weeks depending on the team's workflow.
Example of Cycle Time
Suppose a user story enters development on June 5 and is completed on June 20.
| Event | Date |
|---|---|
| Work Started | June 5 |
| Work Completed | June 20 |
Cycle Time = June 20 − June 5 = 15 Days
Therefore, the team required 15 days to complete the work after starting development.
Visualizing Cycle Time
| Stage | Duration |
|---|---|
| Analysis | 2 Days |
| Development | 8 Days |
| Testing | 4 Days |
| Deployment | 1 Day |
| Total Cycle Time | 15 Days |
The Cycle Time includes all activities that occur after work starts until the work is considered complete.
Why Cycle Time Matters
Cycle Time provides insight into how efficiently a team completes work. A shorter Cycle Time usually indicates a faster and more efficient development process.
Teams use Cycle Time to improve predictability and identify areas where work gets delayed.
Benefits of Measuring Cycle Time
- Measures team efficiency.
- Improves delivery predictability.
- Identifies workflow bottlenecks.
- Supports continuous improvement.
- Helps optimize development processes.
- Provides data for future planning.
Cycle Time vs Lead Time
Although Cycle Time and Lead Time are related, they measure different aspects of the workflow.
| Cycle Time | Lead Time |
|---|---|
| Starts when work begins. | Starts when the request is created. |
| Measures team efficiency. | Measures customer wait time. |
| Excludes backlog waiting time. | Includes backlog waiting time. |
| Focuses on execution. | Focuses on overall delivery. |
Lead Time and Cycle Time Example
| Event | Date |
|---|---|
| Feature Requested | June 1 |
| Development Started | June 5 |
| Feature Delivered | June 20 |
Lead Time: June 1 → June 20 = 19 Days
Cycle Time: June 5 → June 20 = 15 Days
The four-day difference represents the time the work item spent waiting before development started.
Factors That Increase Cycle Time
| Factor | Impact |
|---|---|
| Large User Stories | Take longer to complete. |
| Too Much Work in Progress | Creates bottlenecks. |
| Manual Testing | Slows completion. |
| Technical Debt | Reduces development speed. |
| Dependencies | Teams wait for other teams. |
| Frequent Interruptions | Reduces productivity. |
How Scrum Masters Can Improve Cycle Time
- Encourage smaller user stories.
- Limit Work In Progress (WIP).
- Remove impediments quickly.
- Reduce team dependencies.
- Promote automated testing.
- Improve collaboration among team members.
- Address technical debt regularly.
Cycle Time in Scrum
Scrum teams often monitor Cycle Time to determine how efficiently work moves through a sprint.
A consistently low Cycle Time indicates that the team is capable of delivering work quickly and predictably.
Significant increases in Cycle Time may indicate workflow bottlenecks, unclear requirements, resource constraints, or technical challenges.
Cycle Time in Jira
Jira automatically tracks issue status changes, making it easy to calculate Cycle Time.
Scrum Masters can use Jira reports and dashboards to monitor Cycle Time trends and identify opportunities for improvement.
Real-World Example
Consider an Agile team developing a new search feature for an e-commerce website.
| Activity | Duration |
|---|---|
| Requirements Analysis | 2 Days |
| Development | 5 Days |
| Testing | 3 Days |
| Deployment | 1 Day |
| Total Cycle Time | 11 Days |
The team took 11 days to complete the feature after work began. By analyzing this Cycle Time, the team can identify areas where improvements can reduce future delivery times.
Best Practices for Managing Cycle Time
- Break large stories into smaller tasks.
- Review bottlenecks regularly.
- Automate repetitive activities.
- Reduce handoffs between teams.
- Improve Definition of Done.
- Monitor Cycle Time trends continuously.
Key Takeaways
- Cycle Time measures how long work takes after development begins.
- It reflects team efficiency and workflow effectiveness.
- Cycle Time excludes backlog waiting time.
- Shorter Cycle Times generally indicate better performance.
- Scrum Masters use Cycle Time to identify bottlenecks and improve delivery speed.
- Cycle Time is a critical metric for continuous improvement in Agile teams.
Conclusion
Cycle Time is a powerful Agile metric that helps teams understand how efficiently they complete work. By monitoring Cycle Time, identifying bottlenecks, and continuously improving processes, Agile teams can increase productivity, improve predictability, and deliver value to customers more quickly.
