Does anyone have other suggestions for finding maximum productivity and focus while working from home?
Also, treat work-time as you would if you were at work. I.e., don't do household chores during work hours.
I made a list of things that help me concentrate that I can pull out when I'm having trouble concentrating.
For example certain types of music help me immerse; having a clean (uncluttered) desk helps me.
Before lunch is better than after lunch, etc.
Remember your home office is not your office, and you will have to be disciplined to stay productive in the long term.
The biggest distraction I've found while working with a remote team is dealing with IM. In practice I've found this can be more distracting than low level banter in the office - you can tune out to this, and it's always obvious if a message is directed at you. Not so with group IM, where unread messages may or may not be directed at you. In short, and assuming your colleagues are happy with it, I recommend going 'Do not disturb' for a few hours every day while you focus on work without distraction.
Realize that working from home may not be for you.
For example if your peak productivity time is between 4pm and 8pm and staying late at the office was a strategy you used before telecommuting, that's not going to be effective if you are working from home and have a family.
Some people cannot work when there are dirty dishes in the sink or the dogs want a walk or the front door needs a coat of paint.
