Working remotely is different to working together in an office, of course. It requires different skills and a different type of motivation, ime. It also requires far better communication skills. Weak communication skills can kill productivity.

An observation I've made is that folk who hide their mistakes can be a serious problem. You need the complete opposite, so that when someone shouts for help, then it's all hands to the pump. Those folk they can be hugely disruptive without realising it.

Regarding nudging: Ask when something will be done (with units of work that are small enough to make this viable), and get them to commit to it. If they repeatedly don't deliver, and fail to communicate the problems, then you know you have a problem.

Nudging is usually a sign of poor (or no) communication and lack of confidence.
