• Obtain the Global Visibility
– Modeling Development Lifecycle
• Intuitive Integration
– How to propagate the changes
• Unified Development Capability
– Same working environments (Tools, Interface and Process)

8. Stream helps us
#
• Benefits of Stream
– Codeline management (main/dev/rel types)
– Modeling development cycle
– Intuitive developer actions (green, gray and red arrows)
– Easy workspace management (One workspace)
– Inheritance of parent stream attributes

9. #
 Stream Depots
 Collaboration with Legacy Depot
 Two layer Depth
- Easy to find the target/source
 Stream Type
 Main / Dev / Rel / Virtual

10. Stream Naming Conventions (ex..)
#
• For Release Stream
– Prjname_CustomerName_Rev#
• For Dev Stream
– Target_Purpose ( No restriction )
• For Virtual Stream
– Prjname_CustomerName_Rev#_bin

11. #
• Global Collaboration
– Seamless distributed working sites
• Visualization of Project Roadmap
– Lifecycle management from Dev to Rel
• Increasing the Productivity
– Same tools in everywhere
