An increasing number of studies have begun conducting economic experiments in field, rather than laboratory settings. We directly compare results from laboratory and field valuation experiments. After controlling for unengaged bidders, results indicate field valuations were greater than laboratory valuations. Results are discussed in the context of recent literature on commitment costs.  2002 ...

Requirements elicitation describes the activities needed to determine the requirements of a software system. It is essential to the success of a software development project. Requirements elicitation techniques are used by requirements engineers to discover the information needed to build systems that will satisfy the needs of stakeholders. This paper presents different types of software system...

A conceptual model can be an important instrument to support the software functional requirements elicitation because it promotes better understanding of a domain. However, the representation quality of the conceptual model depends on the expressivity of the language used. OntoUML is a proposed language to solve expressivity problems. Nevertheless, OntoUML models are complicated to build for no...

Due to their complex nature, data warehouse (DWH) development projects often fail or significantly exceed budgets. Prior literature has revealed that achieving common understanding in the requirements elicitation phase is a key factor for the successful knowledge transfer and overall success of information systems (IS) development. To closer observe these phenomena, we conducted in-depth interv...

Requirement elicitation is a critical activity in the requirement development process and it explores the requirements of stakeholders. The common challenges that analysts face during elicitation process are to ensure effective communication between analyst and the users. Mostly errors in the systems are due to poor communication between user and analyst. This paper proposes an improved approac...

Identifying and analyzing aspectual requirements manually is very resource intensive due to the broadly scoped nature of aspects and the large volumes and ambiguity of requirements elicitation data. In this paper we present an evaluation of EA-Miner – a requirements-level aspect identification tool. The tool is evaluated by comparing the performance of an analyst using the tool with that of car...

This paper discusses the current shortfalls in support for the pre-coding phases of a discrete event simulation project. The paper then presents a process modelling technique, Simulation Activity Diagrams (SADs), developed to specifically support the initial requirements gathering phases of a simulation project. The paper concludes with an outline of proposed future developments to the modellin...

There are moments within the process of creating an artifact, for instance at the initial requirements gathering or in the assessment phase, that users input data is collected. There may be an impact directly on the results of the analysis of this data if, for some reason, this data input is not accurate. This paper will focus on a specific phenomenon, known as the Conjunction Fallacy, which ma...
