Lead time and cycle time are two important concepts in the business world that are often confused with one another. Lead time is the total amount of time it takes to complete a process from start to finish, while cycle time is the amount of time it takes to complete a single iteration of a process. Lead time is often used to measure the overall efficiency of a process, while cycle time is used to measure the efficiency of individual steps within the process. In the Agile methodology, lead time is used to measure the time it takes to complete a feature from the time it is requested to the time it is delivered, while cycle time is used to measure the time it takes to complete a single iteration of a feature. Lead time is often used to measure the effectiveness of a process, while cycle time is used to measure the speed of a process. By understanding the differences between lead time and cycle time, businesses can better understand how to optimize their processes for maximum efficiency.
