The product description for the 'classroom-based training materials' states that the classroom training should take no more than one day to deliver to attendees.
During stage 3 the Training Delivery Manager informed the project manager that it will take three days to deliver the training to attendees. Project assurance has confirmed that the project will still be delivered within project time, cost and quality tolerances. Therefore, the project manager has granted a concession for the product.
Is this an appropriate application of the 'change' theme, and why?
