- Work closely with Project Managers, Product Owners, Business Analysts, technical leads and third parties to agree accurate estimates, sequencing and resourcing.
- Track progress against plan, analyse variances and trends, and provide clear forecasts on milestone confidence, slippage and recovery options.
- Identify and manage schedule, dependency and resource risks, supporting mitigation planning and tracking actions to closure.
- Produce high-quality programme reporting, including weekly/monthly status packs, dashboards and RAID updates, ensuring data integrity and consistency.
- Facilitate planning workshops and schedule reviews, constructively challenging assumptions and driving clarity on next steps.
- Provide scenario planning and impact assessments to support decisions on scope, sequencing, resourcing and delivery approach.
- Contribute to the continuous improvement of planning processes, tools and good practice.
Key Deliverables
- An integrated, baselined programme plan with aligned project and workstream schedules, clear milestones and a critical path.
- Regular planning insights and reports, including schedule health, milestone confidence, variance analysis and forward look.
- Robust schedule risk and dependency logs, with agreed mitigation actions tracked to completion.
- Clear impact assessments and scenario plans to support informed delivery decisions.
Experience
- Proven experience in project or programme planning, scheduling or PMO within complex change or technology environments.
- Confident using MS Project, Excel and standard reporting tools.

- Experience supporting large-scale system or business transformation programmes, ideally in regulated or public-sector environments (desirable).
- Understanding of change and implementation planning (desirable).
- Knowledge of RAID management or related delivery controls (desirable).
About you
