It has received its fullest description in his Problem Frames: Analysing and Structuring Software Development Problems (2001).
The old system's data flow diagrams can be drawn up and compared with the new system's data flow diagrams to draw comparisons to implement a more efficient system. Data flow diagrams can be used to provide the end user with a physical idea of where the data they input ultimately has an effect upon the structure of the whole system from order to ...
Officials at the state Department of Juvenile Justice did not respond to questions about YSI. A department spokeswoman, Meghan Speakes Collins, pointed to overall improvements the state has made in its contract monitoring process, such as conducting more interviews with randomly selected youth to get a better understanding of conditions and analyzing problematic trends such as high staff turnover.
