Abstract
The function and ability required of products has been upgrading and growing complicated. Therefore, the way in which the Request for Proposal is accurately interpreted is thought to be so important. The comprehensibility of the requirements extraction in the upper process makes great influence on the quality of the materials. Thus, this project looks at the serious loss that can occur if problems exist in the requirements extraction which is tested during the requirements analysis. Within this study, an ambiguity and Non-functional Requirements extraction technique is proposed to prevent such problems in the Request for Proposal during the upper process. First, the proposal request's section that contains ambiguity and Non-functional Requirements is extracted manually. Then, an ambiguity and non-functional requirements are found by both an expert and a non-expert, and the difference is compared to extract requirements that are likely to cause misunderstanding.
