The document introduces IBM's Duplicate Code Detection (DCD) technology, which identifies and helps refactor duplicate code quickly, enhancing code readability and reducing complexity. It emphasizes the importance of addressing code duplication in large information systems to lower defect costs and improve quality. Additionally, the DCD tool supports collaboration among developers through sharing and versioning search results in various environments.

- 3. Time has changed… When daylight saving time change happens… … you pick up your clock/watch and change the time, moving forward or backward an hour.
- 4. Time needs change But you have clocks in nearly every rooms that needs to be changed… It takes time for sure, but the good news is that you know where your clocks are.
- 5. What about your Information System? What is the real cost of fixing a single defect? And would you like to reduce that cost?... What is the size of your code? millions LoC, more?... How much code one of your developer can handle?... How many duplication of code do you have in your IS? Do you have any idea where is that code duplication & how much do you have? How many defects are duplicated in your code?
- 6. But where should I start? What do I need? Need for enterprise-grade capabilities Need for handle large amount of LoC Need code duplicates discovery tooling Need for refactoring capabilities Need to leverage developers Need to empower your development teams Need to assert code quality … Ultimately, I need to be efficient
