5. AT&T Agile Implementation Approach
“Sandwich” approach
• Top-down (management track) and bottom-up (team track)
Loosely-coupled approach
• Independent implementation per each LOB
• Aligned terms, concepts and re-use of learning
Optimizing the whole
• Focusing on the end to end process (not just development)
• Discovery team approach: Idea to Cash
• E2E agile lifecycle management tool from day 1
