What is one quality practice for software development?

Refactoring is the process of improving the design and structure of existing code without changing its external behavior. It is a quality practice for software development because it helps to reduce technical debt, improve maintainability, readability, and testability, and enable faster delivery of value. Refactoring is one of the core engineering practices in SAFe, along with Test-First, Continuous Integration, and Pair Work. References: SAFe for Teams - Know Your Role on an Agile Team, Exam Study Guide: SP (6.0) - SAFe® Practitioner, SAFe for Teams | SAFe Practitioner (SP) Certification, Built-in Quality
