4. Software Transformation
5. Connecting Ideas. Delivering Impact. just put AI on it
6. @duffleit Modern System ✨ Legacy System 🧟
7. @duffleit 60% of Applications are Legacy* 92% of Cost go into Maintenance if you trust Gartner

9. @duffleit Legacy System Modern System ✨ 🧟
10. @duffleit Modern System ✨ Legacy System 🧟 Take the existing COBOL system and modernize it. Autonomous AI & also here Assistive AI Help me with this task
11. @duffleit why depends whom you ask Take the existing COBOL system and modernize it.
12. @duffleit Save Costs Time To Market Rehost Replatform Rearchitect Replace Retire Revisit Reduce Risk Motivators Strategies ⬆ ⏺ ⏺ Execution
13. @duffleit Forward Engineering Reverse Engineering Rehost Replatform Rearchitect Replace Retire Revisit Execution Analyze Document Extract Specify Build Integrate Decompose Plan Test Cut Over
14. @duffleit Rehost Replatform Rearchitect Replace Retire Revisit Execution Analyze Document Extract Specify Build Integrate Decompose Plan Test Cut Over Reverse Engineering Forward Engineering Value Driven Modernization
