Job Description

Job Description:

The Change and Comms Manager is responsible for driving the change management and communications strategy for Digital Experience products, specifically focusing on driving MGS productivity, user experience, and self-service adoption. This role ensures high user adoption by managing change for both net-new project deployments and ongoing Business-As-Usual (BAU) product updates. The role requires a balance of program-level coordination and local implementation, leveraging a regional network of Change Agents to drive consistent adoption across the business.

Context and Scope

Reporting to the Digital Experience Director, the Change and Comms Manager operates within a matrixed product environment to deliver the change and communications for the Digital Experience products. Product Managers and Owners will be responsible for driving the execution of change.

This role is essential in connecting the program and communications with MGS CA and other workstreams to strategically enable scale to the Segments and achieve the experience and self-service objectives of Digital Experience products. The associate must fluidly transition between structured program-level reporting (such as SteerCo preparation) and hands-on, tactical change execution for day-to-day BAU support.

  • Training & Enablement: Partner with product teams to design training approaches, use cases, and self-service materials that enable users and reduce support tickets.

2. Stakeholder Engagement & Governance

  • PMO & SteerCo Reporting: Provide change readiness metrics, progress updates, and risk management inputs to Program PMO leadership and Steering Committees (SteerCo).

  • Sponsor & Leadership Alignment: Partner with and coach Product Sponsors and Managers so they have the knowledge and ability to support teams and deliver key messages.

  • Cross-Functional Collaboration: Connect the program change and communications with MGS Corporate Affairs (CA), P&O, Finance, and key external partners to manage program dependencies.

Job Specifications & Qualifications
