The Experiment Board (by Javelin) is tool that was developed based on the learnings from their first tool, the (Lean) Validation Board, which was used by over 20,000 entrepreneurs around the world. They’ve improved it to get you up and running even faster, teams who use this are ready to run their first Lean Startup experiment within 5 minutes! The Experiment board is free to download and includes a PDF, a Google Spreadsheet version, and instructions. The PDF document can be printed out as a 60cm x 90cm (2 ft x 3 ft) poster that you can use to put on your (office) wall. If you have a virtual team you can use the included Google Spreadsheet of the Experiment Board to collaborate with your team online.
