Agile Adoption Story in LGE (Aps2010)

Woogon Shim
Woogon Shim

This document summarizes a presentation about improving software development practices at a company. It discusses bringing in experts to teach test-driven development, refactoring, and applying agile principles like Scrum. Over several years, it shows how the company gradually adopted more practices like automated unit testing, design principles, embedded agile, and combining agile with Six Sigma. Coaching individual teams and a whole module helped advance skills and standards, but spreading the changes more widely remained a challenge.
