Role Overview & Strategic Importance

The Core Transformation Management Office (TMO) within McKesson’s Medical‑Surgical business is seeking a Portfolio Manager to play a critical role in driving enterprise transformation initiatives with significant financial and organizational impact.

The Transformation Portfolio Manager (P4) is responsible for initiative-level governance, readiness, and value tracking across a defined subset of enterprise transformation initiatives.

Operating within the Transformation Management Office (TMO), this role stays close to assigned initiatives to ensure they are clearly framed, analytically sound, and progressing toward milestones with accurate visibility into scope, value, risks, dependencies, and decision needs. The Transformation Portfolio Manager partners directly with initiative owners and business stakeholders to surface red flags early, validate assumptions as work progresses, and ensure changes in effort, complexity, or value are identified and escalated before initiatives fall off track.

A core focus of this role is enabling timely leadership decisions by helping initiative teams frame issues and options in a decision-ready format — including clarifying tradeoffs, pros/cons, financial implications, and recommended paths forward — so TMO leadership and the P5 can effectively funnel the right topics into governance forums such as the ELT/PMO stand-up.

This role acts as a connector and integrator at the initiative level, enabling the TMO to maintain comparability, transparency, and readiness across initiatives without becoming a delivery organization or an ad-hoc analytics team.
