Based on the experience and role, Andrew's estimated hourly rate is around $75. This is a relatively modest estimate, considering the operational excellence manager role typically requires a strong educational background and experience in managing teams. The UK location also affects the rate, with salaries generally lower compared to other regions. A benchmark for operational excellence managers in the UK is around $50-$100 per hour, with more experienced professionals potentially earning higher rates. Given Andrew's 17 years of experience, I've estimated his rate at the lower end of this range.
