As you know, deadlines are important and thus you need to ask for them or suggest them for every task you discuss.

It’s the only way to ensure there is an agreement for delivery and you reduce you learning curve for common tasks to your project.

You will have team members that consistently self assign, execute, and complete tasks without any followup from you and that’s the best on your project but for all team member you will need to confirm effort to completion.

This too for vendors and yourself.
