Shortly after I began my IT career 40 years ago, a pioneering study was released that showed a significant productivity drop if a computer-based system took longer than two seconds to respond to user input. That two-second limit was the gold standard (or at least a target) for many years. Developers of client-server and web-based applications somehow lost sight of that standard – possibly related to the network latency that practically guaranteed significantly longer waits. This study seems to confirm what we old dinosaurs have known for decades.
You know how long it takes for my work computer to respond when I add a single data form? FIFTEEN SECONDS. No wonder I never get any work done.
