Negotiation - Requirements engineering involves communication and negotiation among various stakeholders. -- It is inevitable that conflict situations arise among the requirements.

One needs to promote negotiation mechanisms among the stakeholders. Its result can have a significant impact on the acceptance of the final system. - Another form of handling conflicts consists in adopting prioritisation techniques, to sustain the choice of the requirements subset to be implemented at each instant. ### 5.

Validation +- The objective is to ensure that the requirements define the system desired by the client. +- One should examine the requirements document through inspections or technical reviews of the specifications, to evaluate if it describes the intended system. +- Validation is a testing activity. +- While the requirements engineering activities are conducted, it is necessary to execute tasks that allow requirements to be verified and validated. + +### 7.
