I had the problem with this colleague. We participated in a dozen of meetings over the previous several weeks. I mean teleconferences. There always was this issue – I did not quite understand her. I heard her but not as good as the rest of the participants. The same thing was happening today. And suddenly one of the guys told her: “Looks like your mic is up the headset, can you take it down.” Shock and laugh. Boy, was it loud now? It did the trick.
The moral: how often we miss something obvious that, once implemented, makes a huge difference and dramatically changes the situation. Go, figure.
