Enterprise BSS transformation
CBS Upgrade
Holding 15 customer channels together while the billing core changed underneath them.
The product context
What had to work beyond the project plan
A core billing upgrade is not one release. It is a coordinated change across middleware, customer channels, third parties and business owners, with every dependency converging on the same cutover window.
Made readiness visible
Converted a complex integration landscape into channel-level checkpoints, owners, risks and acceptance decisions that could be reviewed without losing the technical reality.
Governed the seams
Focused the cadence on the places large programmes fail: middleware dependencies, third-party deliverables, test evidence, unresolved decisions and cutover ownership.
Kept the programme moving
Used RAID governance and escalation paths to protect the go-live date while organisational change was happening around the programme.
Delivery system
The path from complexity to outcome
My PMO role was to make the handoffs visible, decisions timely and readiness testable.
