Abstract

Software requirements are not simply collected or obtained. The process is called 'elicit' and eliciting software requirements is challenging due to the existence of multiple resources with multiple perspectives. Requirements elicitation acquires appropriate techniques and skills in order to get the right requirements. In general, the set of requirements must describe the stakeholders' needs to ease their business processes and must be feasible in order to be realized within time, cost and technology constraints. The requirements statement is the basis for every project, defining what the stakeholders need and also what the system must do in order to satisfy that need. Further, defects in requirements are the most numerous in the software lifecycle and also the most expensive and time-consuming to correct. Therefore, it is crucial to minimize defects in requirements to save later effort to correct them. One promising approach to attain cost effective software requirements is to introduce formal negotiation. This research focuses on providing a framework for empirical study to estimate the benefit of negotiation. Benefits come in savings of rework when a defect has to be detected and removed at a later stage of development or operation. The benefit from savings depends on the severity of the defect and the impact it would have had on the development project; this may vary with the development phase in which it would have surfaced. The framework attempts to provide a guideline to empirically assess the effectiveness of requirements elicitation practice in order to reduce the number of defects and therefore estimates the savings resulting from negotiation. The reduction of defects here is presented in the terms of economic benefit obtained through negotiation.
