  abstract = {Stakeholder goals identified during requirements elicitation are usually
	informal and incomplete statements about a system considered for
	development. There are numerous approaches for capturing such informal
	models. For example, we have found the EasyWinWin requirements negotiation
	method to be an efficient way for attaining consensus among the success-critical
	stakeholders. The WinWin negotiation model captures stakeholder goals
	as win conditions, issues, options and agreements. When such a model
	has to be transformed into more formal representations, quality becomes
	particularly important. Approaches for validating such informal models
	can increase quality and provide guidance for further refinement
	of requirements. Inspection is a proven approach to identify defects
	and is also applicable to early life cycle artifacts. This paper
	reports on an empirical study demonstrating the usefulness of an
	inspection technique for requirements negotiation models. The study
	employs a conservative economic model, which considers the effect
	of defect slippage during development on defect detection benefits
	from inspection. The main finding of the study is that inspection
	is an economic validation technique for requirements negotiation
	models. There are, however, certain limitations that need to be studied
	in more detail.},
