TMO+Sprint

Led multiple DAY ZERO and DAY ONE joint release executions for TMUS Release Engineering

T-Mobile U.S.

Seattle, WA

T-Mobile US and Sprint officially merged in Q1 of 2020, leading to immense technical integration complexity between the two companies. The challenge was to drive the consolidation forward with minimal business disruption across all impacted parts of the organization.

MY CONTRIBUTIONS

  • DAY ZERO and DAY ONE Release Delivery
  • Impacted stakeholder identification
  • Short-Interval Schedule planning & implementation
  • Pre-Deployment & Night of Release coordination
  • Joint SIS planning & delivery across Legacy TMO and Sprint
  • Performance test planning & execution
  • Near real-time Executive Leadership status sync
  • Issue tracking and resolution via JIRA

How I Helped

With less than 4 weeks from rolling on to Merger Approval, I quickly ramped up to understand the release scope for DAY ZERO integration.

By reaching out to impacted stakeholders, department leaderships and fellow peers - I interfaced with points-of-contacts spanning various levels to gather information necessary to building out a Short-Interval Schedule for the roll out of the "New T-Mobile" in their very first Joint-Integration Release.

This resulted in an on-time and defect-free execution of the Deployment plan on the Night of Release.

In parallel, I collaborated with the Performance Testing and Release Engineering teams to improve the way Tasks and Activities were collated and carried out for all scheduled Performance Tests, leading to a reduction in errors and issues during their Execution Runs.

Outcome

  • Collaborated with cross-organizational teams to build out End-to-End Short Interval Schedules for Night of Release execution
  • Successfully delivered all DAY ZERO and DAY ONE project releases on-time and with no defects
  • Improved Performance Testing execution with process improvement refinements
