The following table describes the shape's properties.

The branches of the Decision shape should not converge later, but should represent independent execution paths leading to the ‘end’ shape.
The example of a WRONG scenario below merges the two branches into one shape :
...
The CORRECT way to do this is to duplicate the second decision shape, as shown in the next picture:
...
2. Neither branch of the Decision shape should lead directly to the “End” shape. For such scenario it is better to use “Condition To Execute” property of the shape, and get rid of the Decision shape altogether.
