Business challenge

What needed to be solved

Modernize critical switching infrastructure while protecting business continuity for a 500+ user enterprise environment.

My leadership

How I created delivery control

Owned the integrated plan, maintenance-window governance, RAID management, stakeholder readiness, vendor coordination, change approvals, cutover checkpoints, and rollback readiness.

  • Established scope, success criteria, dependencies, and accountable owners.
  • Sequenced three controlled change windows with formal entry and exit gates.
  • Maintained RAID, executive reporting, communications, and rollback readiness.
  • Coordinated technical validation, business readiness, and post-cutover stabilization.
Measured outcome

Business and delivery impact

Six Cisco Catalyst 9300 switches were replaced with Catalyst 9407 platforms across three controlled windows with zero unplanned downtime.
