Research data

In order to evaluate our approach to software development, we have conducted a series of sessions with users form different industry fields in which we have tried to simulate the classic requirements gathering interview with the client. The sessions were limited to the 2-hour time frame and the goal was to build a Kroki model based on the user specification. Users were voluntarily joining the research and there was no restriction regarding the level of expretise, age or profession. Main conditions for picking suitable participants were that they use an information system as part of their daily work routine and that they are not software engineers or programmers of any sort. Also, users were asked to think about a potential new information system they needed personally or at work or about the improvements that their existing software lack. The sessions objective was to try to negotiate the formal specification of that idea in the form of a Kroki model.

So far, we were able to orchestrate 9 individual sessions with the users which details are shown in the table below:

Evaluation instrument

After the sessions, each user has been given a survey which served as a measurement instrument used to collect subjective impressions from the sessions as well as some general information about the participants.

The survey consisted of three questionnaires:

All survey files can be found on the following links:

Each question group consisted of a number of closed questions and, with the exception of the background test, a free section for user comments and suggestions. Users answered each question by choosing an item on the 5-point agreement scale with the terms Strongly agree and Strongly disagree on the oposing sides of the scale.
