Impact of a visual decision support tool in project control: A comparative study using eye tracking
تأثیر یک ابزار پشتیبانی از تصمیم بصری در کنترل پروژه: یک مطالعه مقایسه ای با استفاده از ردیابی چشم-2020 This paper presents the results of a comparative study where two decision support tools in project control have
been selected: the S-Curve and Activity Gazer. The objective of the research is to characterize the impact of the
visual decision-support tool in project control on the project planners decision. Using eye tracking, a withinsubject
experiment was conducted with 17 participants where they were asked to make a diagnostic on a project
portfolio. Results show that, despite the fact that a representation using the S-Curve helps reduce the time of
diagnostics, both tools seem to have the same effect on the quality of the diagnostic by the participant. Also, we
find that a representation where Activity Gazer is present is less mentally demanding than a representation where
the S-Curve is present. These results suggest that the S-Curve could be improved to reduce the mental charge
needed to analyze it and that new visualization tools could help project planners in their daily work. Keywords: Project control | Visualization | Eye tracking | Activity Gazer | Project management | Decision support |
