In engineering organizations, growth is strictly related to producing fast and reliable software. In the software development industry, nearly everyone, from developers and engineering managers to C-level executives, wants to deploy software more quickly, write better code, and provide end users with greater value.

A key component of Agile software development is focusing on the right metrics. As an engineering team leader, it’s your job to increase velocity by constantly improving how your team works. Regarding accelerating the software delivery process, Lead Time and Cycle Time are two essential velocity metrics to measure and monitor.

Although understanding the nuances between Lead Time vs. Cycle time is critical if you want to harness their true potential, it’s just as important to have an overview of these two velocity metrics to reduce and optimize them.

At Waydev, we understand the challenge of accurately measuring these metrics. Our platform offers you instant access to this data so that you can assess DevOps velocity and performance in no time.

The article aims to clarify the differences and similarities between Lead Time and Cycle Time, why it is essential to measure, and how to optimize DevOps processes by reducing the two metrics.

What is Lead Time for Changes?

Lead Time is a term borrowed from the manufacturing method “Toyota Production System.” It calculates the time between a customer placing an order and the time the order was shipped and received by the customer.

Lead Time for Changes is specific to software development. It is a velocity DORA metric that measures the amount of time needed to implement, test, and deliver changes to the codebase. This metric measures the time between committing the code and sending it to production. 

In other words, Lead Time for Changes calculates the time elapsed between the identification of a requirement and its fulfillment. Simply put, it is an indicator of how long it takes for a client’s requested feature to be completed. 
With Waydev’s DORA metrics dashboard, Lead Time for Changes and the other three metrics are pulled automatically in a single dashboard so you can make informed decisions based on actionable insights related to your team’s performance.

How to calculate Lead Time for Changes?

There are two ways to calculate Lead Time for Changes to spot bottlenecks and assess areas for improvement.

The traditional way means asking your developers about their average Lead Time for Changes, manually checking Jira statuses, creating reports, and holding daily standups to gather all information to obtain a clear overview.

Lead Time for Changes is then calculated by comparing the time each revision was initiated with the time at which the same revision completed the deployment pipeline’s final action. You can only imagine that this is not only a tiresome process, but also an inaccurate one that is susceptible to flaws.

Nowadays, thanks to data-driven engineering management analytics platforms like Waydev, this metric is pulled automatically due to our CI/CD integrations, such as GitHub Actions, Jenkins, and CircleCI. 

The benefit is that it reduces the deployment’s overall time by accelerating deployment through automation. With our development analytics feature, all DORA metrics, including Lead Time for Changes, are displayed and tracked automatically in an easy-to-read dashboard without requiring you to aggregate all this data manually.

What is Cycle Time?

Cycle Time is also a velocity metric in manufacturing and an important strategic tool for project management. Cycle Time measures the time an engineering team takes to finish a project. Simply put, it reflects the time spent producing a feature until it is ready for shipment. 

It is an indicator of development processes’ velocity, showing how fast an engineering team can deliver a product to customers, from when work has started until the moment it’s been delivered. It all comes down to the team’s development velocity.

As an engineering manager, you’re probably already using DevOps KPIs to measure your development pipeline and make informed purchasing and budgeting decisions. 

However, your road to success is unfinished without something to link these crucial metrics together. To differentiate yourself from the competition, use a Cycle Time analysis to make the connections between your KPIs and improve your production process.

How to calculate Cycle Time?

When calculating Cycle Time, you need to know your production time and how much of a product/feature is actually produced in this time. Cycle Time is calculated by dividing the total production time by the units produced.

You also need to consider the time when production was paused, meaning the waiting period between active production work.

At Waydev, we measure Cycle Time from the first commit until that feature is deployed to production and made available to users. Thanks to our CI/CD integrations that pull DORA metrics automatically, you’ll have access to Cycle Time and gain insights about the development processes’ velocity with no manual input.

What are the main differences between Lead Time and Cycle Time?

The main difference between Lead Time for Changes and Cycle Time is that Lead Time is measured from the customer’s perspective, whereas Cycle Time is measured from the internal process point of view.

Lead Time for Changes includes Cycle Time and depends on it, whereas Cycle Time does not have Lead Time for Changes.

Lead Time for Changes measures the time from receiving the order to delivery, while Cycle Time measures the time taken to complete the production process.

Another key difference between Lead Time for Changes vs. Cycle time is the units in which they’re measured. Lead Time is measured in elapsed time (weeks, hours, seconds), while Cycle Time is measured in time per unit/process/task.

The relationship between Cycle Time and Lead Time for Changes is described by Little’s Law as follows:

Lead Time = Cycle Time x WIP (Work-In-Progress)

Importance of measuring Lead Time for Changes and Cycle Time in Software Development

Lead Time for Changes and Cycle Time are essential velocity metrics to track in DevOps and they can help engineering managers understand the dynamics of their team’s workflow. 

These metrics give insights into the relationship between an order being placed and completed. They’re also a good indicator of your engineering team’s capability to deliver value to your customers.

By measuring Lead Time for Changes, engineering managers can understand the time it takes for their customers to receive their orders. If the Lead Time is high, it can negatively affect customer satisfaction and the overall user experience.

By analyzing Cycle Time, engineering managers can determine the overall efficiency of their production unit. With this information, they can spot the inefficiencies and bottlenecks that may slow things down.

To increase productivity, efficiency, and cut costs, Lead Time for Changes and Cycle Time should be reduced as much as possible, as this is something highly valued by customers. In a competitive environment, such as the software development industry, you must ensure that your customers receive valuable products and services in the most efficient way possible.

As an engineering manager, you’ll help increase your organization’s overall productivity and deliver a better customer experience by measuring, reducing, and optimizing Lead Time for Changes and Cycle Time.
