The model shows that the dimensions of stakeholder expectation (scope, time, quality, and cost) are related. Stakeholders trade different values for scope, time, quality, and cost when establishing the requirements for a software project. Prioritizing their expectations can help stakeholders to make trade-offs more easily and effectively. Different software project stakeholders make different decisions to support their interests. They have different inputs feeding their decision process and different expectations about the outcomes of their decisions. For instance, stakeholders have different levels of tolerance for the risks associated with the decisions that they make.
