Maria, an NHS buyer, needs cost savings due to budget cuts.

With a collaborative supplier, the appropriate approach is Win–Win (integrative). Both sides aim to create savings while maintaining partnership value. Win–Lose would damage collaboration, while Lose–Lose sacrifices value on both sides. Win–Perceived Win is based on optics rather than actual balance. By adopting a win–win approach, Maria ensures sustainable cost reductions while protecting critical NHS supplier relationships.
