With two unreleased platforms, dispersed vendors, and a hard deadline tied to the tournament schedule, the early instinct was to load the experience with features gesture controls, social annotations, multi-angle viewing. I pushed back: for a live sports event, the core need is simple see the game clearly without the experience breaking. So we prioritized ruthlessly around three pillars: streaming quality (4K, low latency, reliable bitrate adaptation), spatial audio (stadium-grade immersion), and reliability (zero crashes or buffering during key moments), deliberately deferring gesture controls and social features rather than risk a flaky first impression. The PoC shipped on time with zero major issues, proved the concept to Deutsche Telekom's executive team, and laid the foundation for AR live sports viewing as a viable product line validating that for a PoC, quality and reliability beat feature breadth.
