Our company develops a software for alarm receiving centers. In our software our customers can use a visual code editor http://pfau.de/images/beispiel002.gif to program their own processes for alarm reactions. That is actually our main selling point. They can control the user interaction (what to do, who to call, etc) in reaction to an alarm, access all the data to change process outcomes in response to data or user interaction and automate a lot of processes (filling forms, mailing reports and even automated invoices). They can even call external programs (on other computers) and fill and read databases to interact with other systems. That generally works well as long as people use simple flows and standardise a lot. But as soon as people start to program complex flows you can really see who is a “programmer in disguise“ and who is “just a user thrown in way over his head”.
