I have got to do a CRM installation this week so I have been reading the implemenation guide, which I have to say is an excellently written document and full credit for Microsoft, you can download that here
It’s funny at the time I studied and passed the CRM 4 installation certification I wasn’t installing CRM and just wanted to study for it to learn more about CRM and it’s various components but now I am very happy I did that certification because I know have a good grounding about all the different parts of CRM
The document is good but the one weakness it has is it doesn’t have any pictures, pictures can be very reassuring when you see the same picture in the guide as you have on screen.
Luckily there are some other fantastic CRM 2011 installation guides out there
