Job Summary

Lead the organisational change required to make Unity (WMFTS' ERP) become 'how we run the business', and build a consistent, high performing change capability across other priority programmes. You will be accountable for adoption, behavioural change, role capability and value realisation for the Unity deployment, while line managing and coaching a small team of change managers who support additional enterprise initiatives. This is a senior, visible role. You will lead through influence and credibility, not hierarchy; bring calm authority during cutover and stabilisation; and ensure OpCo leadership owns adoption, not just system go live.

Key Responsibilities
  • Unity ERP Change Leadership
    Own the change strategy and execution for Unity across 40+ OpCos.
    Drive business readiness, role clarity, training and on the floor support through cutover and hyper care.
    Stand up and sustain a strong super user network and process owner community.
    Balance global standard processes with pragmatic local realities within agreed guardrails.
    Track adoption and behaviour change (not just training completion), closing gaps quickly.
    Lead the business in defining true value and benefits, then measure our success of these post deploy.
  • Enterprise Change Leadership
    Build and lead a small centre of excellence for change, line manage other change managers assigned to non ERP programmes.
    Establish and maintain common standards, playbooks and tooling (impact assessment, readiness criteria, comms and adoption KPIs).
    Run a portfolio level change heatmap and capacity view to sequence major changes sensibly and avoid overload.
  • Executive Communication & Decision Framing
    Provide clear, concise sponsor packs on adoption risks, readiness, stakeholder sentiment and residual change debt.
    Frame trade offs and recommendations; elevate design/scope items to TDA/EDA with crisp options and implications.
  • Governance & Integration
    Operate within group ERP governance and the Unity programme cadence, integrated with PMO, data, training, testing, cutover and hyper care.
    Ensure OpCo leaders commit to tangible adoption actions and hold themselves to account.
  • Delivery Oversight (Change Workstream)
    Define and enforce entry/exit criteria for change activities (training readiness, cutover comms, hyper care support).
    Lead structured lessons learned between waves; improve the change playbook continuously.
  • Benefits & Value Realisation
    Partner with Finance, Process Leads and business stakeholders to baseline value and benefits (OKR), define adoption indicators and track early value signals (reduced workarounds, first time right data, cycle time improvements).
Skills/Experience
  • Significant experience leading business change at scale across multiple sites or countries (operations/manufacturing/supply chain exposure is ideal).
  • Hands on leadership of ERP or major process transformation change, comfortable with role based training, cutover comms, hyper care and post go live adoption.
  • Proven ability to influence senior stakeholders (OpCo MDs, functional heads) without formal authority.
  • Strong judgement: able to simplify complexity, set boundaries and create calm under pressure.
  • Disciplined approach to readiness, adoption metrics and benefit tracking-beyond attendance and go live.
  • Experience building a small change capability (coaching, standards, toolkits, QA).
  • Excellent written and verbal communication; clear, concise executive materials.
  • Comfortable with travel and on site presence during readiness, cutover and hyper care.
  • Formal change or PM certifications desirable, though not essential for the right candidate; leadership, credibility and ERP change experience are a must.
