Summary


OSS collaboration software services are great
tools!
Use of Web-based systems to manage software
works well



Scales from small to large projects
Facilitates an agile process
Centralizes all project information (code,
communications, coordination)
Many Government agencies using GForge
internally and externally (for OSS)
Agile languages can help ANY development
process (from simple to complex)
