There’s a reason many of us put off getting a cell phone until we have to: for the first couple days (or weeks, in some cases), everything takes longer. There’s the upfront investment of time to set preferences the way you like them, authenticate passwords, and learn which buttons do what when. Getting a new device makes you think again, makes you pay attention. It can be tiresome, inconvenient and sometimes frustrating. This same scenario plays out on a large scale across organizations when making a large technology change, and it’s called a productivity dip.
