"Keep the Lights on Technology" is the IT that is required for any organization to function. Email, Internet, Wifi, Phones are examples of this category. We sometimes call this "Break-Fix" technology. "KTLOT" should be like a utility, it should just work.
When you turn a knob, water comes out. When you flip a switch, the light turns on. KTLOT should work the same way. If it doesn't just "work" something is wrong. This technology should just melt into the background.
