Prototyping in industrial software projects-bridging the gap between theory and practice

Benefits of and barriers to involving users in medical device technology development and evaluation

“…This review has found that it is not possible for some potential users to contribute adequately in development and evaluation of specific medical device technologies, particularly the more complex technologies (57), because they might not possess sufficient technological knowledge and understanding about products based on such technologies (46). This point should act as a warning to manufacturers that they should not expect solutions to complex technical problems from such users concerning medical device technologies, particularly those of a novel nature.…”

“…This point should act as a warning to manufacturers that they should not expect solutions to complex technical problems from such users concerning medical device technologies, particularly those of a novel nature. However, engagement with such users may be useful for the purpose of identification and clarification of user requirements and experiences, as well as in relation to vital features of the products (46). However, despite the general value of user involvement, it was found that such involvement does not provide any certainty that the products or technologies so developed will be always successful (5;10), or be perfect and function smoothly (18).…”

Information systems prototyping in practice

“…Lichter et al (1994) call a prototype used to initiate a software project a `presentation prototype'. Generally, the purpose of early prototypes is to elicit or validate requirements.…”

Evolving beyond requirements creep: a risk-based evolutionary prototyping model

“…[OS94]. Evolutionary prototyping has been successfully employed in "real world" projects [LSZ93,NC98].…”

“…• the clarification of management and user requirements [LSZ93]; • the ability to uncover missing or previously unknown requirements [Gra91,Dav92]; • the flexibility to meet changing constraints for software systems [NC98,FD89]; • the provision of a method whereby users, management, and developers can communicate about systems [Gra89,Gra91,LSZ93];…”
