Project management: does the supplier's first offer set the terms of negotiation?
When a project requires an external service, securing a discount can easily feel like successful negotiation. The managerial question is more precise: how can we prevent the supplier's opening figure from becoming the sole benchmark for an acceptable agreement?
What the literature establishes
Amos Tversky and Daniel Kahneman (1974, Science) describe anchoring: an initial value can influence a numerical judgement even when it provides no relevant information about the quantity being estimated. Adjustment away from that value may remain insufficient. For a project manager, this suggests that a discount calculated against the original quotation is not, in itself, evidence of a favourable price.
What negotiation adds to the mechanism
Adam Galinsky and Thomas Mussweiler (2001, Journal of Personality and Social Psychology) show, in experimental negotiations, that first offers can anchor outcomes and benefit the party making them. Their experiments also show that this advantage can disappear when recipients focus on information inconsistent with the anchor, particularly the other party's alternatives or their own target. Useful preparation therefore involves more than planning a counteroffer: it means establishing an independent reference point.
The premature conclusion
One might conclude that buyers should always name their price before the supplier does. These studies are not sufficient to turn an experimental advantage into a universal rule, particularly when the technical scope remains uncertain. An opening offer may contain genuine information about production constraints; resisting anchoring does not mean ignoring it. (our executive and employee training programmes)
What the evidence cannot guarantee
The experiments cited do not reproduce the full complexity of project procurement: quality requirements, dependence on a provider, an ongoing relationship and changes in scope. They therefore cannot quantify the savings that independent preparation would generate in a particular company. Conversely, measuring only the discount obtained preserves an ambiguity: a substantial discount may start from a high baseline.
A practical check in Vevey
In Vevey, amid global food businesses, group headquarters and Riviera SMEs, an exercise in SHR's Project Management programme could focus on purchasing an external service on a comparable scope basis. Before opening the commercial offer, the manager records a documented reference range, non-negotiable requirements and an alternative option; after negotiation, they compare the final price with that reference rather than solely with the initial quotation. The verifiable measure is the proportion of reviewed procurement files containing this reference dated before the offer was opened, supplemented by the difference between the final price and the initial range. This monitoring checks decision-making discipline; without an appropriate comparison, it does not prove that the method caused savings.
