Using protocol analysis to explore the creative requirements engineering process
Protocol analysis is an empirical method applied by researchers in cognitive psychology and behavioural analysis. Protocol analysis can be used to collect, document and analyse thought processes by an individual problem solver. In general, research subjects are asked to think aloud when performing a given task. Their verbal reports are transcribed and represent a sequence of their thoughts and cognitive activities. These verbal reports are analysed to identify relevant segments of cognitive behaviours by the research subjects. The analysis results may be cross-examined (or validated through retrospective interviews with the research subjects). This paper offers a critical analysis of this research method, its approaches to data collection and analysis, strengths and limitations, and discusses its use in information systems research. The aim is to explore the use of protocol analysis in studying the creative requirements engineering process.<br /
Proposition of a PLM tool to support textile design: A case study applied to the definition of the early stages of design requirements
The current climate of economic competition forces businesses to adapt more than ever to the expectations of their customers. Faced with new challenges, practices in textile design have evolved in order to be able to manage projects in new work environments. After presenting a state of the art overview of collaborative tools used in product design and making functional comparison between PLM solutions, our paper proposes a case study for the development and testing of a collaborative platform in the textile industry, focusing on the definition of early stages of design needs. The scientific contributions presented in this paper are a state of the art of current PLM solutions and their application in the field of textile design; and a case study where we will present, define, and test the mock-up of a collaborative tool to assist the early stages, based on identified intermediary representations
Modified Stage-Gate: A Conceptual Model of Virtual Product Development Process
In today s dynamic marketplace, manufacturing companies are under strong
pressure to introduce new products for long-term survival with their
competitors. Nevertheless, every company cannot cope up progressively or
immediately with the market requirements due to knowledge dynamics being
experienced in the competitive milieu. Increased competition and reduced
product life cycles put force upon companies to develop new products faster. In
response to these pressing needs, there should be some new approach compatible
in flexible circumstances. This paper presents a solution based on the popular
Stage-Gate system, which is closely linked with virtual team approach. Virtual
teams can provide a platform to advance the knowledge-base in a company and
thus to reduce time-to-market. This article introduces conceptual product
development architecture under a virtual team umbrella. The paper describes all
the major aspects of new product development (NPD), NPD process and its
relationship with virtual teams, Stage-Gate system finally presents a modified
Stage-Gate system to cope up with the changing needs. It also provides the
guidelines for the successful implementation of virtual teams in new product
development.Comment: 24 page
