Why are some developers not aware of the functional flows? It’s like I am coding this module, why should I know the complete flow. My module is working fine. But you have to have a complete understanding of the system. Isn’t it? It works like that in every sphere – look at the bigger picture. Where do you fit, or where does your code/module fit in the overall flow. System architecture and System’s User perspective go hand-in-hand. Everyone in a project should have a clear understanding of these two aspects.
