Activity or Scheduled Job?

[7oaks]

I have a chicken and egg issue here.  I need to create over 70 Scheduled Jobs and associated Activity for our Facilities team and can't get my head around the process. Am i scheduling a job first and then the Activities or vice versa.  A comprehensive to do list would be greatly appreciated if anyone has the time.  Thank you, Debby

p.s. I have tried both ways and can see some of the Activities in My Tasks list but dont need to as i'm in IT Support but not all of them depending on how i created them.
