PDD notation - Activities

Q: What is the naming convention (naamgeving) of an activity?

- At the lowest level the activity names all start with a verb: Identify users, Develop system interaction, Estimate license costs, Describe requirements. - At higher levels phase names can be nouns: Requirements , Implementation .

Q: What are the different types of activities?

- Standard activity : activity without sub-activities (atomic activity) ; - Complex activity : with sub-activities Open activity : sub-activities are known in this context, i.e. the meta-model details can be found in this or another meta-model of the method engineering study at hand. Closed activity : sub-activities are not known in this context.

Q: What are concurrent activities?

Concurrent activities are executed in parallel. After completion synchronization is needed before continuing.

6 important questions on PDD notation - Activities

What is the naming convention (naamgeving) of an activity?

- At the lowest level the activity names all start with a verb:

Identify users, Develop system interaction, Estimate license costs, Describe requirements.

- At higher levels phase names can be nouns:

Requirements, Implementation.

What are the different types of activities?

- Standard activity: activity without sub-activities (atomic activity);
- Complex activity: with sub-activities

Open activity: sub-activities are known in this context, i.e. the meta-model details can be found in this or another meta-model of the method engineering study at hand.
Closed activity: sub-activities are not known in this context.

What are concurrent activities?

Concurrent activities are executed in parallel.
After completion synchronization is needed before continuing.

What are conditional activities?

Conditional activities are activities that are only carried out if a pre-defined condition is met.

How should a conditional activity be modeled?

The condition is stated as a Boolean expression between square brackets [ ].

When should a role be mentioned in an activity?

A role should be mentioned in an activity when in some methods explicitly is stated by which individuals or organizational role the process is to be carried out.
