Daily contractor rates and hourly contractor rates are treated separately. When calculating average contractor rates, daily rates are not derived from quoted hourly rates or vice versa.
The chart provides the 3-month moving total beginning in 2004 of IT contractor jobs citing TDD within the UK as a proportion of the total demand within the Processes & Methodologies category.
