“ ... there are no simple 'right' answers for most web design questions (at least not for the important ones). What works is good, integrated design that fills a need--carefully thought out, well executed, and tested. ”

-- Steve Krug, Don't Make Me Think, p. 136

Atwood, Michael E., Burns, Bart, Gairing, Dieter, Girgensohn, Andreas, Lee, Alison, Turner, Thea, Alteras-Webb, Sabina and Zimmermann, Beatrix (1995): Facilitating Communication in Software Development. In: Proceedings of DIS95: Designing Interactive Systems: Processes, Practices, Methods, & Techniques 1995. pp. 65-73.

“Effective communication is critical to the success of a software development project. It factors into the productivity of individuals and organizations, and has particular impact when change occurs. Yet communication is generally left unsupported by the software development process and by the communication infrastructure. We address this issue in the context of two software development projects at NYNEX through a conceptual framework called Design Intent. There are three innovations in our approach. Design Intent encourages stakeholders to engage in active listening, enables stakeholders to collaboratively construct a consistent understanding of the development effort, and provides a communication infrastructure for stakeholders to share ideas and participate in discussions.”

Alteras-Webb, Sabina and Dekker, Debra K. (1994): Measuring Perceived Task Difficulty Using Magnitude Estimation: A Demonstration and Replication. In: Proceedings of the Human Factors and Ergonomics Society 38th Annual Meeting 1994. pp. 335-339.

“The proliferation of sedentary, more cognitively demanding computer-mediated work, calls attention to the need for methods to measure mental work load. The prevent research describes two experiments in which participants performed a machine paced task of entering five and/or nine digit zip codes into a computer. The zip code data was prevented on a computer screen for twelve four minute trials where the rate of zip code presentation varied from trial to trial. Using the psychophysical scaling method of magnitude estimation, participants made a judgment of task difficulty after each trial period. In Experiment 1, four females participated in a repeated measures within-subjects design performing each digit task condition for five consecutive days. In Experiment 2, a between-subjects design was adopted where 42 females performed either the five or the nine digit data-entry for only one testing session. Regression analyses using the independent variable of stimulus presentation rate and the dependent variable of judgments of perceived difficulty resulted in R{squared}s of .90 or better for both digit conditions in both experiments. T-tests were conducted to see if different task parameters would affect difficulty judgments; these were statistically significant to the .001 level in both experiments. The results support the notion that magnitude estimation is a reliable method for scaling subjective perceptions of difficulty, which may be an important component of mental workload.”
