Guide to Lead Time for Scrum Performance Metrics
Lead Time is a crucial performance metric in Scrum that helps to understand how long it takes for a work item to go through the whole process, from the time it is requested until it is fully executed.
Importance of Lead Time:
The significance of Lead Time resides in its capacity to reflect the efficiency of a Scrum team. It provides transparency into the workflow and helps to identify potential bottlenecks, leading to improved project management and better quality deliverables.
Understanding Lead Time:
Lead Time begins when a new item enters the system (a request has been placed or a task has been added to the backlog) and ends when this item is finished. This timeframe includes both working time and wait time.
How it works:
Measuring Lead Time involves tracking each task from the moment it enters the backlog until it's completed. It is calculated as: Lead Time = End Time - Start Time.
Exam Tips: Answering Questions on Lead Time:
When answering questions about Lead Time, remember to clearly outline its purpose and importance. Be sure to understand and explain the difference between Lead Time and Cycle Time. Discuss its benefits and limitation. Finally, be prepared to calculate Lead Time using given data in hypothetical scenarios.
