Objectives Of Marketing Plans

Marketing plans describe the current situation for the product, service, or brand, and the plan for the future. What are the objectives of the marketing plan?  In other words, why is one needed?  What are the possible outcomes if marketers do not have a marketing plan? Provide specific examples to support your ideas. In replies to peers, discuss whether you agree or disagree with their position and justify your reply with specific reasons, facts, and examples.
