Many useful software products are started with tightly coupled  “spaghetti” code that just works.   As lines of code and complexity increase, teams often struggle to make modifications and add new features without impacting the entire application.  As a result, previously successful applications start missing dates and suffering from degrading quality.  OSGi can help by introducing a modular design that decouples the architecture, separates concerns, and manages dependencies.  Unfortunately it often takes a few missed dates before a team realizes how important modularity is.  Don’t let your existing product become a victim of its own success.    Learn how to introduce modularity to existing software projects using Apache Felix.  Discover how your application can evolve into a pluggable standards driven framework.  It’s never too late to reap the benefits of modularity!
