What is a roll-out plan?

What is a roll-out plan? I tried searching on Google, but without much success. I found http://www.project-open.org/en/tutorial_rollout_plan, but I still don't understand what a roll-out plan is for a startup. Does it have a synonym?

Any examples (with images) are more than welcome.

In startup terms, "Roll Out " generically equates to launch.. as in release a product for use outside of the company .

"Roll out" is used more frequently in corporate / enterprise circles - esp. where development and deployment costs are budgeted & tracked independently.

Some project deployments are relatively simple (launching a blog, for example) - while others require migration of existing data, coordinated training, etc. Products that require complex setup tasks sometime refer to a "roll out plan" that details what is needed to use the product-- esp. when the cost to roll out the product exceeds the cost of the product itself (Think SAP ).
