“Software is eating the world”
– M. Andreesen
Your software sourcing & crafting strategy says which
ecosystems you will be part of
Agility (both speed and flexibility) is determined by your software strategy

Constantly Changing SoftwareConstantly Changing Software
Requires New MethodsRequires New Methods
Source code becomes more important
(shown, shared and modified)
Since building is a constant task,
the process becomes more important than the result
The heart of the game is to constantly learn new skills

Platforms, APIs & Open Source PracticePlatforms, APIs & Open Source Practice
White-box integration with source code
There is a treasure trove of value in the existing open source communities
APIs is a service architecture game :
modularity, event-oriented architecture, data exposition
Good software is built incrementally through feedback
