Ideas _ people said the more you talk about your ideas the more refine it becomes. I think this is true. Did you ever experience when you talk to more people you generated a lot more ideas? When people give you feedback it triggers another dimension of your ideas? If you are, so where do you keep all these ideas? It should be in a marketing plan.
Resource Plan _ in marketing, there is only one thing that's scarce: RESOURCES. Some people have a lot of money but lacked ideas and another group is the other extreme; more ideas and less money. Many of us probably the later than the former! In the marketing plan we will tackle things like people to hire, pricing, distribution plan, sales programs budget and so on.
