Generalization is DeterministicImperative.

Definition

<font color””#2d2d2d”>A Sequence controls the order of Activities or Steps by defining a simple sequence.</font>

Examples

A Sequence might contain two Sequences of Activity – one for Round 1 Activity of the Research and the second for Round 2

Explanatory notes

Unlike TemporalConstraints, Sequence is NOT pairwise. However, a group of TemporalConstraints can specify an order with more precision than Sequence.
