HIMEKAMI: an end-user system development enviromnent based on Lyee theory

We propose a new development environment "HIMEKAMI" for true end-user system development. It is designed under the condition that automatic coding process based on Lyee methodology is available. There, an evolutional system-development step by step approach is proposed to improve system achievement and the user's development level. As input items are the most important for end-user development, we reconstruct them from the view point of end-user development. Then, we analyze and categorize them, from the view point of end-user development. Then, we find that some items can be omitted and some input automatically. And, we propose a visual input method, which supports easy "Flowchart Design" and "Window Design" by end user. To evaluate our proposed methods, the number of input items in an example of system development by HIMEKAMI is compared with that by a traditional Lyee oriented tool, "LyeeALL2". The results from the experimental system show that 82.2 % of the items input by LyeeALL2 can be input visually in HIMEKAMI. We confirm that HIMEKAMI with Lyee automatic coding function has the possibility of being able to achieve an end-user system-development environment.
