Explanation
A non-negotiable demand by a stakeholder during the requirements prioritization session is one that does not allow for any trade-offs, compromises, or alternatives. It is a demand that must be met regardless of the impact on other requirements, the feasibility of the solution, or the value to the organization. A stakeholder who insists that all requirements are ranked as high is making a non-negotiable demand, as this would prevent any meaningful prioritization and allocation of resources. Communication, cost-benefits ratio, and cost are not non-negotiable demands, as they can be negotiated,adjusted, or balanced with other factors during the requirements prioritization session.
