These actions, these or this

Hi,

Question:
Should I say "these actions, these or this"

Sentence:
I would allocate new tasks and review our existing tasks during our group meeting.
I would set a deadline for each new task and monitor our progress.
I did these actions / these / this to influence the team.

My opinion:

"these actions" can be used, because I did more than 1 action, such as, allocating new tasks and reviewing existing tasks.

"this" can be used, because the word "this" refer to the whole situation and all the things I did.

"these" cannot be used.

Thanks
