John Lewis Partnership’s platform engineering team discusses the metrics that they use to measure the value of their developer platform.

Google Cloud Platform provides a suite of cloud computing services for building, deploying, and managing applications and infrastructure on Google's global network. Developers can learn about cloud-native development, machine learning, and big data analytics to leverage GCP's scalable and reliable cloud infrastructure for their projects.

John Lewis Partnership's platform engineering team evolved their measurement strategy from basic lead-time tracking to a comprehensive approach combining DORA metrics with qualitative developer feedback. They implemented Service Operability Assessments, adopted the DX platform for surveying engineers, and built a Technical Health feature in Backstage to track platform adoption across four categories: technical health, operational readiness, migrations, and broader engineering practices. The team emphasizes balancing objective metrics with subjective feedback, using data to enable team improvements rather than just reporting, and adapting measurement strategies as the platform matures.
