This study has   focused on system development approaches and system development   methodologies. The purpose of the study has been to present a view on the   current situation of different development approaches (agile, traditional,   iterative and hybrid) and methodologies by highlighting the situation from a   number of perspectives. Questions that are answered are: which system   development approaches and methodologies that can be said to be most   frequently used based on the respondents, if the mentioned approaches can be   given certain characteristics based on a selection of factors and the   respondents' attitude towards the approach they practice. The study has been   conducted as a survey where the answers have been obtained via social media.   The result shows that agile methodologies dominate and that they are often   included in various forms of hybrid and agile approaches. Furthermore, it has   not been possible to create an in-depth knowledge of the approaches based on   the selected factors. Finally, it is noted that project members who practice   an agile approach have a great confidence in the approach and have a strong   conviction that it contributes to increase the quality of the software.
