T-Mobile revolutionizes initiative approvals across departments

T-Mobile, one of the largest wireless carriers in the US, faced significant bottlenecks in initiative approvals due to complex, multi-departmental workflows and lack of a centralized system. Relying on tools like Excel, the manual process was slow, cumbersome, and error-prone. To overcome these obstacles, T-Mobile adopted Microsoft Power Platform, building the 'Orbit App' using Power Apps (canvas and model-driven), Power Automate, Power BI, Dataverse, and Microsoft Teams integration. The application centralized all initiative requests, approvals, and documentation, supporting executive, project member, and team lead collaboration. The app supports a multistage approval process, with input forms that dynamically adjust based on the type of promotion or initiative. Data-driven dashboards, embedded Power BI analytics, and adaptive Teams cards enhance visibility and process flow. Orbit scaled to accommodate a 150% annual growth in initiatives, especially following T-Mobile's acquisition of Sprint. The integration of RPA via Power Automate facilitated real-time synchronization of disparate systems. Role-based security and permissions provide granular control. Since the rollout, error rates dropped from 7% to 0%, process throughput improved 11x, and the organization saved $4M and over 97,000 hours. The solution also enabled rich document management, secure attachments, versioning, and automated workflow triggers. Orbit has been available to over 40,000 T-Mobile employees, with 250+ daily users and up to 600+ active each month. The initiative illustrates how low-code platforms can enable both professional and citizen developers to rapidly build and maintain mission-critical workflows. The Orbit solution’s architecture leverages custom connectors and Dataverse APIs to blend both canvas and model-driven app benefits in a single cohesive solution.
