Part 1
There various ways through which a marketing manager can apply marketing management functions. As a manager, I would focus on market analysis function to determine the changes in the market environment. Through the analysis, I would be able to acquire the correct and complete information regarding the market operations that would assist me in tackling the other functions. SWOT analysis would be a guiding principle in during this step.
Secondly, I would foster using marketing planning to form a basis of the information received from the market analysis step. This would assist me in developing marketing strategies to guide me towards goals attainment. I would further implement which is the third marketing management function. This step would involve putting the plan into practice as encourage the other members to work towards attaining the goals of the organization. Last, I would apply the control function that would involve measurement and evaluation of the plans to determine the level of goal attainment then make the necessary corrections (Ruiz, 2011).
Part 2
I would explain the benefits of a marketing plan to show the client that a marketing plan is an important tool for his business success. I would explain to the client on the basic importance of a marketing plan as a guide for any business. I would show him how a market plan assists one in focusing on all the aspects of marketing which involve product, place, promotion and price focus. I would make him understand that failure to use a marketing plan may make one not to consider all the 4ps of marketing which are very vital for the business success (White, 2012). Besides, I would make the client understand that a marketing plan helps in stimulating the flow of business operations from production to marketing of the product thus helping the company in enhancing efficiency in operations since control is guaranteed. This is not possible if an investor operates without the tool since everything he or she does is based on guess work.
