You could offer to sit with him while he works through a similar problem to you, to see where he wastes time, creates work for himself or duplicates tasks. You can then be the voice telling him when to move on.

It sounds like he would benefit from a closer inspection of his working practises. Perhaps he needs to be managed in a different way. For example same amount of work just delivered as smaller tasks with shorter deadlines to avoid overwhelm. Maybe to start with, instead of him being part of an hourly weekly meeting, maybe he needs a 10 minute chat per day to help him to catch up, prioritise and plan the next day. This obviously would be the responsibility of his manager to take on.

Perhaps some training in planning out his working day in advance would throw out some interesting changes in how he learns to manage his own time.

I think the worst thing that could be done is to restrict his working hours which would add an extra level of worry - so he is sitting at home more stressed than if he was working.

The most important thing is to help him catch up so he is then receptive to support helping him keep on track.
