Team Topologies in action - early results from industry - ITARC 2021 - 2021-10-18

Since the book Team Topologies was published in 2019, organizations around the world have started to adopt Team Topologies principles and practices like Stream-aligned teams, modern platforms, well-defined team interactions, and team cognitive load as a key driver for fast software delivery and operations.

We will look at examples from these organizations:

- Footasylum gives fashion-focused youth a multi-branded retail experience mixing global sportswear household names with emerging brands and its own stable of in-house labels. Founded in 2005, Footasylum now has 70 stores across the UK and a thriving ecommerce platform, with revenue of £260m per annum and over 2500 employees. Footasylum used Team Topologies patterns to revolutionize their ecommerce platform.

- PureGym is Britain’s largest gym chain - the first to gain over 1 million members. As PureGym expanded, so did the need for software to enable their members to book and manage gym sessions. Since 2019, PureGym has re-aligned its teams and team interactions based on Team Topologies patterns, helping to scale the engineering teams and improve flow.

- uSwitch / RVU, one of the UK’s leading consumer price comparison websites, has grown a modern platform from scratch, allowing stream-aligned teams to focus on consumers needs, offloading infrastructure provisioning concerns to the platform which also provides cross-cutting services around scalability, security and data management

- Wealth Wizards is a UK company making financial advice affordable and accessible to everyone through online tools and apps. The engineering division at Wealth Wizards has used the Team Topologies ideas around team cognitive load to help right-size their teams and align teams to the most important flows of business change.

For each of these examples, we explore how the ideas and patterns in Team Topologies were useful to the organization and the results of the changes.
