TL;DR
Samsung's first Tizen phone (the Z1) was a make-or-break bet for a non-Android platform in price-sensitive markets. I coordinated 350+ engineers across geographies to ship it on time — and it sold 1M units in five months.
The Problem
The Z1 targeted emerging markets like India, where Android already dominated. Success could prove Tizen viable; failure could kill it. The hardest part was scale and alignment: 350+ engineers across R&D centers in Korea, India, and beyond, each with their own way of working — and issues took too long to travel up through leadership before reaching the right team, risking fragmented features and launch delays.
The Approach
I consolidated requirements for core apps like video telephony and media playback so they worked reliably across networks and markets, and I made coordination the product. Knowing the full org chart, I acted as a high-speed routing channel between QA and engineering — re-routing tickets straight to the right owners instead of waiting for escalation, cutting days off resolution.
The Solution
I bridged R&D centers with joint reviews, resolved ownership conflicts, kept everyone aligned on dependencies, partnered with QA to define test cases reflecting real-world conditions (not just lab scenarios), and worked with marketing so the go-to-market plan matched what we could actually ship.
The Impact
The Z1 launched on time with all critical features and sold 1M devices within five months in price-sensitive markets — proving Samsung could execute a non-Android smartphone program and giving leadership confidence to expand Tizen.
