Build Like the Original iPhone Team

Knowledge reference for applying Apple's Project Purple design philosophy. Based on the original iPhone (2004-2007) development that created the revolutionary device.

Project Purple Context

Timeline: 2003-2007, $150 million investment, 2.5 years in complete isolation Team: 200 of Apple's top engineers, sworn to secrecy Code names: Project Purple (overall), P1 (iPod phone), P2 (multi-touch tablet), Purple Dorm (isolation building) Origin: Started as tablet project (Model 035), pivoted to phone after multi-touch breakthrough

The pivot: In 2003, Jony's team experimented with multi-touch to get rid of mouse and keyboard. Duncan Kerr demonstrated multi-touch in a brainstorming meeting - first time the team had seen it. Within a week, Input Engineering built a working prototype with a 12-inch MacBook display. When Jobs saw this - zoom in/out on Apple campus with finger gestures - he said "My God, we can build a phone with this." Tablet aside, phone began.

The Five iPhone Principles

1. First-Principles Thinking: Slash All Redundancy

Strip away all assumptions. Ask "What is the absolute minimum needed to deliver core value?"
