Supporting outage planning and coordinating investment activities to minimise operational disruption.

Analysing large datasets to improve portfolio performance and support decision-making.

Producing performance reports, scorecards and governance information for senior stakeholders.

Facilitating stakeholder workshops and planning meetings to align priorities and delivery plans.

Driving continuous improvement across planning, investment management and portfolio governance processes.

Providing subject matter expertise on planning methodologies, resource allocation and portfolio optimisation.
