Governance & Reporting

• Produce clear, concise reporting for programme leadership
• Highlight milestone confidence, key risks, issues and decisions required
• Support governance forums and assurance reviews
• Contribute to service transition, operational handover and lessons learned activities

• An accomplished communicator who can influence stakeholders at all levels
• Comfortable working across matrix organisations and supplier environments
• Methodical, proactive and highly organised
• Resilient under pressure and able to navigate complex challenges
• Skilled at turning technical plans into measurable delivery outcomes
