 Welcome back. In Unit 3, you learned how to write a business plan and how that plan can be the foundation for growing a company. You learned how important it is to have correct and accurate information in your plan and that you should update your plan often since market conditions are always changing. In your plan, you identified the objectives for the business. This is great, but how do you put those into action? This is where Unit 4 comes in, where you will learn about marketing strategies. The first step is to define marketing and how it creates value for the customer. You will learn how to do market research using primary and secondary sources and what to do with that information. You will uncover the outside forces that impact the ways in which companies market their products and services. And finally, you will learn about the marketing plan, which helps a company with its marketing and advertising activities. Take this efficient time to read and review all of the resources. And as I mentioned before, it's a good idea to take notes as you go along. This will help you be better prepared for the final exam. Enjoy the unit and we'll see you here at the beginning of Unit 5.
