How do you manage a project that has dependencies across multiple technical teams, such as network engineering, IT, and a business unit, especially when those teams have different priorities and release schedules?

Situation

I was tasked with launching a new digital prepaid reload channel that required back-end API integration with IT, network capacity provisioning from engineering, and a marketing rollout from the business unit.

Task

My responsibility was to align the disparate roadmaps of these three teams into a single, deliverable project plan that met the business's go-to-market deadline.

Action

I first facilitated a 'dependency mapping' session where each team lead laid out their key milestones and critical dependencies in a shared timeline. I then set up a weekly 30-minute cross-functional stand-up strictly focused on dependency hand-offs, not status updates, to catch blockers early. I created a shared risk register that highlighted each dependency as a 'high' priority item, and I personally confirmed all hand-off acceptance criteria with each team. For the IT API release, I negotiated a feature freeze window that allowed Engineering to test the capacity load during dry runs without interference from other projects.

Result

The project launched on the target date with zero revenue loss from the first day. The cross-functional stand-up became a template that the program manager later adopted for other inter-departmental projects.
