Consultation involves actively involving stakeholders or counterparties in decision-making. By seeking input, it fosters a sense of ownership, increasing commitment to negotiated outcomes. It is particularly effective when the negotiator has low positional power, as it shifts dynamics from authority to collaboration. Unlike coercion or compliance tactics, consultation builds engagement and long-term trust, which is critical in complex procurement where buy-in is essential for contract success. CIPS stresses its role in building influence where direct authority is limited.
