Case Stages doesn't have a sequential flow
I decomposed a case in to 6 stages (A,B,C,D,E,F) where, the first stage is mandotory, last one is the resolution stage and the other stages are non-mandotory.
At the end of the first stage, the user has to select an option. According to the selection, the case advances to a single stage out of B,C,D,E or F. The completetion of any non-mandotory stage (B,C,D,E) goes back to stage A. The F stage will resolve the case.
My problem is, Is this case decomposition conceptually correct? Because it doesn't have a sequential stage flow.
I'm quite new to Pega, so I would appreciate any idea.
