Hi, I'm working now on a big system that consists of many subsystems , each subsystem depends on the other. I wrote a usecase for this system , but I note that I have many processes in my usecase ( more than 40 processes ! ) . it looks like this :

• Group subsystem:
  • add Group.
  • remove Group.
  • join to Group.
  • upload file.
  • create poll.
  • remove file.
  • remove poll.
  • write post/topic
  • close post.
  • edit post.
  • ....
• Messages Centers
  • send message
  • view inbox
  • read message.

and so on ..

each user interacts with these processes .

• How can I reduce the number of these processes?
• Is it possible to divide the usecase processes into many pages?
