Plans that never leave the office and are used exclusively for internal strategic planning and management might use more casual language and might not have much visual polish.
On the other end of the spectrum, a plan that is destined for the desk of a top venture capitalist will have a high degree of polish and will focus on the high-growth aspects of the business and the experienced team that is going to deliver stunning results.
A one-page business plan is exactly what it sounds like: a quick summary of your business delivered on a single page.
Specifically, it’s the time to review your progress on milestones and to compare your actuals against your financial projections.
A real business plan is always wrong—hence the regular review and revisions—and never done, because the process of review and revising is vital.
