Requirements determine how an Information System should operate. Requirements Engineering errors become failure reasons of the Information System. In this paper we propose a Web-based focus group method to overcome many problems of the requirements elicitation activity. Collaboration is promoted in discussions involving all stakeholders to achieve consensual decisions. The proposal was evaluate...

This paper describes an action research study which focussed on requirements capture for a subscription-based business-to-consumer (B2C) electronic commerce (EC) system. The study used a recently developed approach to requirements elicitation, the Business Rules Diagram (BRD) Method. The BRD method was adapted somewhat during the study and was found to be helpful in addressing difficulties of r...

As software systems become more and more complex with a multitude of stakeholders involved in development activities, novel ways of conducting the process of requirements elicitation and analysis are to be found. Therefore, this paper introduces a method for collaborative requirements elicitation and decision-supported requirements analysis. Accompanying this method, appropriate tools and techn...

This paper presents the preference ratios in multiattribute evaluation (PRIME) method which supports the analysis of incomplete information in multiattribute weighting models. In PRIME, preference elicitation and synthesis is based on 1) the conversion of possibly imprecise ratio judgments into an imprecisely specified preference model, 2) the use of dominance structures and decision rules in d...

This study investigates the effect of four types of oral corrective feedback, namely, explicit elicitation, implicit elicitation, explicit recast and implicit recast on the most commonly mispronounced phonological features among Iranian EFL learners through immediate uptake and retention. Five classes were randomly categorized into four experimental groups and one control group, each with 18 in...

Requirements elicitation is a complex process that requires stakeholders in teams to collaborate, go through decision-making processes to arrive at consensus. During the requirements elicitation processes, stakeholders who have different backgrounds, view points and understandings, need to clarify, capture and uncover user/client requirements in an efficient and effective manner. However, there...
