Hello Experts,

I am in the process of helping one of my HR colleagues with the definition of tasks & projects performed by the active directory team [including tier 1, 2 and 3], and we need your help to provide the following information:

Define daily/weekly/monthly tasks performed by Tier 1 and Engineers 1

Same as above but for Tier2 and 3 teams

Anticipate projects that AD team might be involved[high level description]

What I would love to see is something like that:

Tier 3

Standard daily task:  Monitor de AD replication; Check DNS/System performance among all domain controllers.

Project : Upgrade the active directory for 2012 R2


I need to cover every single aspect of Directory services per team, Active directory, Federation services, Azure, PKI, ADDS, ADDS, LDAP, AD domain and trust, SSL, and so on. Consider hybrid and on premises environments please
