Recently for actual work we’ve been doing some planning using the Lean Canvas worksheet. For what it’s worth, our blank template is up in SVG (original source) and PDF form. Although there’s a bunch of such sheets around, many of them either have slight variations on the structure, don’t have margins and thus are less directly printable, and so on. These are essentially direct drawings of Ash Maurya’s worksheets in Running Lean, which were licensed under CC Attribution-Share Alike 3.0 terms. Feel free to do whatever you want with these files under the same license.
