Preply is a global language learning marketplace, connecting 50,000+ tutors with millions of learners from all over the world. Since the company launched in 2012, students have signed up for more than 15 million lessons. The engineering organization has grown from a team of 20 to more than 100 throughout its journey, and the company has received over $100M in funding.
The start-up mindset is a crucial part of Preply's culture. This means delivering new features as fast as possible for the engineering organization.
It was in 2021 when Preply's engineering leaders learned about the benefits of measuring DORA metrics to improve their performance. The first step was to understand where they stood.
"By the beginning of 2022, we were measuring three DORA metrics, but Lead Time was not one of them. It turns out it was crucial for us to understand where we were on this metric, so we made it our main goal to start measuring, understanding, and eventually improving it."

Preply chose Athenian as their partner because of the platform's rich interface, the number and quality of metrics provided, and the help provided by Engineering Success with implementing, understanding, and improving those metrics.
And soon they saw that their Lead Time was 40 hours.
"Engineering Success guided us by asking the right questions and pointing us in the right direction to improve the team's performance and the communication between the EngOrg and management." Igor Kasianov - Head of Platform
With the support from Engineering Success and the focus on the right metric, the organization set the goal of reducing its Lead Time to 24 hours in three months without sacrificing the quality of the work.
At Athenian it's possible to see the data for each stage of the Delivery Pipeline and filter by teams, repositories, timeline, and more. Because of this break down, Preply could check which teams were impacting the overall Lead Time the most and which stage was being more affected.
More than that, the organization realized that the teams were working in silos, which could be why Lead Time was so high.
After the analysis, they decided to implement two main process changes:
"The conversations were about finding the blockers for engineers and eliminating them, which helped developers understand that it was not about sacrificing quality over speed and that we could push for faster shipping." Igor Kasianov - Head of Platform
With Athenian, Preply created an action plan thanks to the platform's visibility. The access to the metrics enabled the organization to focus on what mattered to achieve its goals. Developers started to understand they could improve Lead Time with no fear of harming code quality.
Preply's results were impressive: they managed to blow up their goal and reduce Lead Time to 15 hours in only two months.
"Having an experienced team at Athenian to help us through this journey was crucial to make the improvements we made." Igor Kasianov - Head of Platform
The impact was seen all across the company:
