Touching an individual machine means you are losing

My advice would be that if you are touching an individual machine, then you are losing.

For servers that means Puppet, Nagios, single signon, a brutal approach to hardware failure, funnelling everything through a ticketing system, referring to that as the documentation for changes in your configuration repo, documentation written for use by trained people rather than blow-by-blow. Because you end up with a low headcount, then that means evolution of hardware, not once-in-a-blue-moon refresh projects.

For desktops that means either SOA for BYOD, but not some expensive middle ground. It means automating the common helpdesk tasks. It means using the vendor's tools rather than third-party tools, because that lowers your training costs because users get good hits from Google. It means online training.

For networking it means DHCP for IPv4 and Dynamic DNS. It means IPv6 is standard for intranet use (ie, no interior NAT). It means not fiddling with ethernet autonegotiation. It means anycast DNS forwarders. It means cookie cutter cupboard, building and core designs. It means treating VM servers as first class items in the network. It means 802.1x for wireless rather than web landing pages.
