2. Monitoring and managing contractual social value commitments and performance, ensuring delivery against agreed targets and timescales and tracking of KPIs and outcomes.
3. Producing clear, meaningful outputs such as reports, dashboards and case studies for a range of internal and external stakeholders.
4. Coordinating and authoring social value responses for bids and tenders, articulating capabilities, defining credible commitments and setting proportionate, deliverable targets.
