Android = world's mobile platform leaderAndroid historically linked to the Open Source communityConcepts explored may be applied to iOS as well



Why Android on Git ?

Google's internal VC not suitable for external contributorsOpenSource VC needed– Scalable and distributed– Widely used by Linux community– Strong branch and merge capabilities

Linux kernel was on Git since 2005

ALM on Mobile needs change

• Prescriptive, PO and stories

• Time-boxed, 1 month cycle

• Locked Sprint scope

• Adaptive, feedback at 360°

• Limit WIP, release daily / weekly

• Adaptive scope with features and bug-fixes
