2.7 Basic rules

1 - Upon process creation, the system automatically inserts a Start Event (see Chapter 2.1 for details), which is the element that represents the unique point from which each individual process begins.

There can only be one in each individual process, since, the flow starts from a single point. (Figure 1 and 2)

2 - Only a Conditional Task can be attached to the Start Event (see Chapter 2.1 for details). A Conditional Task is a control task in which the triggering conditions of the process can be defined. (Figures 3 and 4).

The same logic applies to the Timer Start Event, the only difference being that only a task of any type except Conditional Task can be attached. (Figure 5 and 6)

3 - Before an Exclusive or Parallel Gateway there must always be a Conditional Task that allows you to define sets of conditions on the basis of which the process will split into multiple branches. (Figure 7 and 8)
