Traditionally business plans have been highly confidential and quite limited in audience. The business plan itself is generally regarded as secret. However the emergence of free software and open source has opened the model and made the notion of an open business plan possible.
An open business plan is a business plan with unlimited audience. The business plan is typically web published and made available to all.
In the free software and open source business model, trade secrets, copyright and patents can no longer be used as effective locking mechanisms to provide sustainable advantages to a particular business and therefore a secret business plan is less relevant in those models.
While the origin of the open business plan model is in the free software and Libber services arena, the concept is likely applicable to other domains.
