At the first stage of CIPS Procurement and Supply Cycle (Understand need and develop a high-level specification), procurement professional mainly negotiate with internal stakeholders. They have a duty toproportionately and constructively challenge specification if there's genuine doubt over the need or how the need is expressed. This is called demand management. Their first duty is to the organisation's treasury, not to functional managers.
Demandmanagement including: negotiation/challenge between procurement and internal stakeholders over the need/requirement/specification. Remember that in any process or product, the greatest opportunity for cost reduction is at the design stage.

In this scenario, Diana has made her proposal right at the opening stage. This is an example of 'don'ts'. Good negotiators are very careful about 'red lines'. If she puts such barrier up too early, the supplier may not try to look for more creative solutions later in the negotiation.
