About the role

  • Own the integrated master portfolio view across all major initiatives (iLottery, CLS, iGaming, Technical Transformations and future strategic programmes).
  • Define and enforce clear distinctions between shaping, intent, discovery and committed delivery.
  • Validate that all commitments are capacity-backed before executive approval.
  • Surface explicit trade-offs where demand exceeds available capacity.
  • Protect executive confidence in milestone integrity and delivery predictability.
  • Reduce volatility and reactive re-planning across the portfolio.
  • Own the structured intake and validation of all new portfolio demand.
  • Ensure initiatives are clearly defined and appropriately sized before entering discovery or delivery.
  • Validate cross-portfolio impact before commitments are formalised.
  • Prevent shadow commitments entering execution without governance visibility.
  • Provide structured trade-off scenarios when new demand displaces existing priorities.
  • Ensure demand governance protects delivery credibility while enabling innovation.
  • Own portfolio-level capacity validation across all delivery verticals (Gaming, Product, Customer).
  • Establish and maintain clear capacity envelopes and saturation thresholds.
  • Translate roadmap ambition into realistic, risk-aware delivery capacity.
  • Identify structural overload early and support informed hiring or sequencing decisions.
  • Ensure contingency is transparent and not hidden within estimates.
  • Support scenario modelling to enable robust executive decision-making.
  • Maintain integrated dependency mapping across a shared, multi-product technology stack.
  • Identify cascading risks across concurrent deployments and product layers.
  • Ensure integrated milestone confidence across programmes.
  • Provide a single, authoritative view of portfolio-level RAID themes.
  • Reduce systemic friction caused by unmanaged cross-team and cross-product dependencies.
  • Own the structure, integrity and evolution of executive and SteerCo reporting packs.
  • Ensure reporting reflects portfolio-level risk, capacity and trade-off reality rather than isolated narratives.
  • Standardise milestone confidence and risk classification across verticals.
  • Provide actionable insight and recommendations to leadership forums.
  • Ensure executive conversations focus on decisions, not data reconciliation.
  • Line manage and develop the Portfolio Analyst.
  • Define portfolio reporting standards, analytical priorities and tooling discipline.
  • Ensure data integrity and signal clarity across portfolio systems.
  • Continually evolve portfolio maturity in line with organisational growth and complexity.
  • Build a pragmatic, disciplined portfolio capability that balances control with delivery velocity.
  • Within the first 90 days:
  • A single, integrated and trusted portfolio view is in place across all major initiatives.
  • Engineering, Product and Delivery are aligned on a single, realistic view of capacity, and it is being used to sequence commitments.
  • All new demand is being entered through a structured Front Door, with no material shadow commitments.
  • Cross-deployment dependencies are clearly visible and openly shared.
  • A new portfolio toolset is implemented and actively used across ALS.
  • Leadership has confidence in what we’ve committed to and when.
