Reporting & insight: produce routine and ad hoc reports to support formal reviews and management decisions on call volumes and resourcing.
Continuous improvement: identify recurring issues, improve processes, document best practice and support implementation of new service offerings.
What you will bring
Proven experience managing people in a contact centre, customer service or target-driven environment.
Strong operational skills: planning, prioritising and allocating work to meet demand.
