The marketing plan is the overview of multi_channel approaches you should be implementing to develop and retain your prospects. It may include a call for brand development and demand generation as well. If your existing strategy is somewhat successful, but you want to grow _ the marketing services it recommends may be more focused on customer relations _ such as social media marketing, email marketing and telemarketing services.
Risk _ in our marketing plan we shouldn't only concern about making money or positive points, we also should address the risk we are taking. for example it is common for a marketing plan to capture things like, "require additional staff to handle sales call", "additional investment from the management budget will increase chances of increasing 10% sales target" and many more. Imagine if you can factor your risk earlier and think through it, wouldn't it be better for you?
