Here are some of our best practices after trying lots of configurations:

• Have a dedicated workstation - something fast and with two nice monitors (22" or 24" or bigger)

• Have 2 keyboards and 2 mice (each person has their own - good for ping pong pairing and hygiene)

• Only have project specific software loaded - no personal email unless common account, no IM unless common account - have a team standard for software and shortcut keys, colors, fonts, etc.

• No personal surfing should be allowed either - keep it as a common workstation.

• The monitors should be cloned to show the same single desktop on both monitors - each developer therefore has their own physical monitor.

• Use a reasonably sized straight desk so the two people can sit next to each other or opposite each other on different sides.

• Get good chairs.

• Have ample whiteboards nearby for brainstorming.
