Ethool usability evaluation

The evaluation included two iterations. Usability was measured between iterations, and improvements between iterations were implemented in the prototypes. The files include the following information:

• Demographic data of the participants including gender, group of participation and number of years in the company.
• Results of the use of the Ethool tool including: expended time and subjective evaluation of it using a Likert of 5 points. Two different files are available corresponding to each iteration (prototype 1 and prototype 2).
• Results of the SUS questionnaire [1] for both iterations (prototype 1 and prototype 2). A Python script has been developed for the SUS questionnaire data process [2], according to the literature [3].
