When developing applications the traditional way the problem that usually arises is the impossibility to match the documentation of the application to its latest development stage. This divergence creates well-known problems and delays the training of employes for project as well as for maintenance and support. For the zen Platform, however, this is no issue. The slogan is:
The model is the application.
When using customary development procedures, the development documentation always needs to be updated manually after changes in the program logic or data structure were made. This is obviously a very error-prone and costly procedure. Using the zen Platform, every application documents itself via the zen Developer.
