During the initiation stage, ABC Company's project manager contacted a specialist external consultancy and asked them to provide a quotation for the 'e-learning course'. This triggered the 'starting up a project' process for the external consultancy. As a result, the consultancy's project manager responded to the request for proposal stating that the 'e-learning course' work package will be a simple project from their perspective.
Is this an appropriate response to the request for a proposal by the external consultancy, and why?
