Our agreement with one of our clients does not specify documenting all of the client’s infrastructure and applications: IT Environment Documentation, for short.
Is our agreement out of normal services scope or I should bill it as out of scope.
Essentially, if I touch it, I document it. It will only make your work easier in the future. Also, if it’s on the network, I notate that it’s there, and what it is. If DHCP with Dynamic IP addresses that aren’t reserved/static, then I notate the MAC address of the device from a network scan. any network scanning tool can do this.
That being said, any documentation you make to manage a client’s system… well, you may need to talk to a lawyer for your specific area about this, but in my own example, if it’s not strictly included in the SOW/Agreement, then I don’t include it. I would then charge the customer a fee to compile all my notes, etc. into a runbook in order to handover any requested information. Any information you hand over, be sure to keep a second copy, signed by the POC so they can’t say you’re withholding their information…
