Sometimes it takes a significant event or change in existing conditions for a business to create a written plan. I think it's safe to say that the state of the economy is a significant change that should prompt business owners to alter the way they've been doing things. If you already have a business plan, it's time to get it out and revise it.
Invention Business Plan Example: The Main Elements : Many different readers and audiences need to see your idea in writing. You will be surprised how many different questions will be asked about your invention. In order to efficiently answer such questions, the document should be designed such that it serves as a detailed yet practical guide and resource to be used by a broad audience. Thus, the elements and content of your plan should be both comprehensive (i.e. can answer most questions about your invention) and adaptable (i.e. can be easily modified) for the purpose of a specific use or audience.
Plan of Operations : Think of this as how you are going to spend a day at your business. How will work get done, from taking orders through to delivery? This can really help you to understand how your business will work and any potential problems or room for improvements.
The three basic actions for growing a business in any economic climate are: improve efficiency (maintain output while reducing inputs, such as time and money); increase volume (produce more in order to spread fixed costs); reorganize the business (change goals, methods and/or philosophy). If you plan to implement one of these, you may as well plan to implement them all. By focusing on one of the above strategies, you will find a ripple effect that causes a need to address the others. This is a good thing.
