Introduce XP Practices to a Legacy E-Commerce Codebase
Overview
What this challenge is about.
You lead a 6-week e-commerce intervention introducing TDD, mob and pair programming, then earn a verifiable certificate.
The scenario
The marketplace (around 35 engineers, mostly mid-level, ships twice a week) has tried 'we should write more tests' for 3 years with no movement — the VP is betting on changing the practice, not the policy.
The Brief
What you'll do, and what you'll demonstrate.
Introduce TDD, pair programming, and refactoring discipline to a legacy team in 6 weeks and produce honest evidence on whether to scale it.
Earning criteria — what you'll demonstrate
- Apply XP practices to a real legacy codebase, not a greenfield project
- Measure the impact of practice changes on engineering metrics honestly
- Coach a team into pair programming and TDD without coercion
- Recommend scale-out (or not) based on evidence, not enthusiasm
