Job purpose:

The PMO Manager will provide clear, accurate and forward-looking portfolio information, governance and control across major initiatives. The role will establish a reliable view of delivery performance, emerging risks, dependencies, defects and change requests, enabling informed prioritisation through the demand management process.

How you will contribute at Janes:

Planning:

• Own and maintain an integrated portfolio plan for major initiatives, providing a clear view of scope, milestones, sequencing, dependencies, resources and target outcomes.
• Coordinate planning across Product, Engineering, Operations and other stakeholders to ensure delivery plans are realistic, aligned and supported by clear ownership.
• Establish proportionate planning standards and ensure initiatives have credible baselines, delivery forecasts, critical paths and agreed assumptions.
• Support capacity and resource planning, identifying constraints, competing priorities and capability gaps that could affect delivery commitments.
• Integrate delivery, testing, operational readiness, Acceptance into Service and non-functional requirement activities into initiative plans from the outset.
• Lead regular planning and replanning activity, assessing the impact of changes and providing evidence-based options and recommendations to support prioritisation decisions.

Management Information and Delivery Visibility:

• Own and manage portfolio management information, ensuring reporting is accurate, consistent, timely and decision-focused.
• Maintain five-sprint delivery views alongside milestone-level views for all major initiatives.
• Provide a clear look-ahead to the end of the current sprint and visibility of work planned for the next sprint.
• Identify delivery trends, emerging risks, constraints and decisions requiring leadership attention.
• Ensure reporting provides a single, transparent view of the current state of delivery.

Governance and Process Management:

• Define, maintain and continuously improve proportionate portfolio and project delivery processes.
• Coordinate dependency management across teams and initiatives, ensuring dependencies have named owners, target dates and agreed resolution plans.
• Facilitate regular issue reviews with relevant stakeholders, including CC and Product representatives, and drive actions through to closure.
• Coordinate user acceptance testing planning, including scope, readiness, environments, resources, entry and exit criteria, defect triage and sign-off.
• Promote consistent governance standards while avoiding unnecessary administration.

Incident Management:

• Facilitate the incident management process from initial identification through to resolution and closure.
• Work closely with the Service Delivery and Engineering Director’s to coordinate and drive the timely resolution of incidents.
• Act as the driving force behind resolver groups, ensuring the right teams engage promptly, ownership is clear and actions are progressed at pace.
• Coordinate incident triage, prioritisation, escalation, stakeholder communication and recovery activity.
• Track incident actions, decisions, dependencies and target resolution times, escalating blockers where required.
• Ensure significant incidents are reviewed, lessons are captured and resulting corrective or preventative actions are completed.

Operations and Service Acceptance:

• Coordinate Acceptance into Service (AIS) activities for major initiatives, ensuring operational stakeholders are engaged from the outset and that service acceptance requirements, owners, evidence and target dates are clearly defined.
• Maintain an integrated operational readiness plan covering support arrangements, monitoring, alerting, documentation, training, service desk readiness, resilience, continuity, security and transition to business-as-usual support.
• Ensure non-functional requirements are identified early, agreed with relevant stakeholders, built into delivery plans and acceptance criteria, and evidenced through appropriate testing and assurance.
• Track operational readiness risks, dependencies, actions, exceptions and service acceptance decisions, escalating gaps that could affect go-live or ongoing service performance.
• Coordinate readiness reviews and go-live recommendations, ensuring entry and exit criteria are met and any residual risks are formally understood, owned and accepted.
• Support effective handover into service, including early-life support arrangements, performance monitoring and completion of post-implementation actions.

Major Initiative and RAID Management:

• Provide project management support and oversight for all major initiatives.
• Establish and maintain clear RAID logs covering risks, assumptions, issues and dependencies.
• Ensure each RAID item has an owner, impact assessment, mitigating action, due date and status.
• Escalate material delivery concerns promptly and provide evidence-based recommendations.
• Track agreed actions, milestones, decisions and outcomes to completion.

Backlog Ownership and Maintenance:

• Review and clean up individual team backlogs, removing duplicates, obsolete items and incomplete records.
• Create and maintain a single consolidated backlog of defects and change requests to provide an accurate view of the current position.
• Apply consistent categorisation, ownership, priority, impact, status and ageing information across backlog items.
• Run a formal backlog review every two weeks with appropriate business, Product and delivery stakeholders.
• Analyse the backlog to identify defects or change requests that require consideration, escalation or prioritisation.
• Provide recommendations and evidence from backlog analysis to feed into the demand management process.

Deliver the following Outcomes:
