Current studying business and this is a question i am stuck on.

"To demonstrate competence in this unit you will need to show that you can design and develop a project plan. Your task is to select an idea, improvement or opportunity that could be applied in a business operation. Describe the business and the project you might initiate. You will need to describe and define the project in context. Explain why such a project would be beneficial. What procedures might you use to ensure that the project was sponsored and supported by the organisation?"

I wondering if anyone has an explain of a project plan?
