This is a workshop I’ve done often, and can easily customize for a group. A nice advantage for groups is that my latest book The Plan-As-You-Go Business Plan reinforces the principles of Business Planning, and is available as a physical book, or free online at planasyougo.com. You can also download my slides as handouts. Slides will change with each delivery, but these are from a guest speaker version at the Disney Entrepreneurial Center.
I strongly recommend bundling either Business Plan Pro or Liveplan.com accounts with the workshop to greatly increase the likelihood of long-term success. People walk away with the tools they need to actually make this happen. Or, as an alternative, bundling the The Plan-As-You-Go Business Plan book costs a lot less.
