Questions around Exchange Scenarios

[zumarius]

For an Exchange Scenario in the systems analysis what is the best way to:

1. Show that two functional exchanges from one actor to the system are associated with a single function within the system?

2. How do I show that two functions within a system or actor should occur simultaneously?

1 - couple of options here:

• use a constraint
• display the same function on the lifeline
• it could also be a naming convention on your FE label
  
  

2. Use a “PAR” Combined Fragment (creating as many operands in it as you have parallel operations)
   
   

I hope this helps.
