Executive Summary
In July 2019, T-Mobile’s Commercial Strategy & Decision Analytics team, under Julie Liabraaten, collaborated with Kumu Agency to transform the brand's digital ecosystem. With the Sprint integration on the horizon, the team evaluated digital channel maturity against key competitors, identified internal governance roadblocks, and built an actionable Digital North Star framework.
Key Findings & Internal Audit

| Navigation | Site structure failed to match actual customer lifecycle tasks. |
| Competitive Gaps | Lagged behind Verizon and AT&T in plan comparisons and trade-in flows. |
| Governance | Priorities were set by internal consensus rather than customer data. |
| VOC Data | Fragmented feedback loops without a unified taxonomy or mapping framework. |
