There are general issues with having just a few large and complex 5250 application sessions:
- The size and complexity may make the navigation model hard to understand.
- It is hard for multiple developers to work on the same 5250 application session simultaneously because their individual work needs to be merged.
- The 5250 application session takes longer to load from the server and longer to initialize.
- Working out navigation paths at execution time takes longer because of the size of the navigation tree.
