Activity (Function or Process)

Design Phase Tasks	P	E	Scoping Objects	Note
Add an activity.	M	D	Intended parent	1
Detail an activity.	M M	D D	Target activity or Any activity in the parentage of target activity
Perform Process Synthesis on a non-elementary process.	M	D	Process	2
Transfer activity to a different parent.	D M	D D	Current parent Plus new parent	3
Change function to process or process to function	M D	D D	Parent activity Child activity	4
Delete an activity and its subordinates-No subordinates are elementary processes with PADs USEd in other action diagrams.	D M D	D D D	Target activity Plus parent activity or Any activity in parentage of target activity	3
Delete an elementary process that has been USEd in other action diagrams.	D M M M M	D D D D D	Process Plus parent process Plus USEing CABs Plus USEing process Plus USEing procedure steps	5

Notes:

Scoping an activity automatically brings its parents into the subset with Access authority. Subordinates have the same protection as the scoped activity.
Process Synthesis can automatically add processes, expected effects, and PADs with stereotypically action diagram statements.
If you scope on a parent activity with Delete, the parent activity is downgraded to Modify. However, you still receive Delete on the target activity and its subordinates and are able to delete them or transfer them to a different parent.
To change a function to a process, all lower-level activities for the function must be processes. Therefore, to change a function to a process, all grandchildren must first be processes.
To remove a PAD, first remove all USE statements for the PAD from any PrADS and CABs.
