In order to evaluate the S-CASE platform apart from the three pilot
          prototypes that were developed and deployed, two (2) hackathon sessions
          were also organised. The purpose was to get potential S-CASE
          users/customers familiar with the platform and its functionality and
          also get valuable feedback from them. 
          
          
            Aristotle University of Thessaloniki (AUTH) has organized two
            hackathons the 1st and 2nd of July 2016: S-CASE hackathon4business
            and S-CASE hackathon4students. Hackathon4business targeted web
            developers of companies and organizations in the vicinity of the
            Thessaloniki area, while hackathon4students was specific to
            undergraduate students in their final years of the department of
            Electrical and Computer Engineering of the Aristotle University of
            Thessaloniki. Centre for Research and Technology Hellas / Information
            Technologies Institute (CERTH/ITI) participated in the hackathons as
            well, with a session on the Web Service Composition tool. Before the
            hackathon4business started, the participants were asked to take a
            survey in order to give information regarding their background and
            after the end of both hackathons, the participants were asked to
            take a survey in order to evaluate S-CASE.

            Based on the responses collected from the pre-hackathon survey, the following results can be summarized below:
              
                -  - All participants have some SW background (different levels of experience)
 
                -  - 21.1% have difficulties in requirements capturing
 
                -  - 36.9% have difficulties in testing & debugging
 
                -  - 63.2% prefer UML diagrams or textual requirements while 36.8% prefer use case templates for requirements capturing
 
                -  - 89.5% have some (front/back-end) web development experience
 
                -  - 72.2% are familiar with Java

            Post-hackathon survey results from 19 participants
            After the hackathon has finished and the developers have seen the
              platform and the procedure, we asked the attendees to fill out
              another survey. Fifteen (15) developers responded and the results
              can be found below.

            After showing the S-CASE platform and the process of creating web
              services to the 46 participating students, we asked them to fill
              out the same post-hackathon survey. The 41 responses can be found
