Performance measurement: constitutes the last but not the less important stage of the marketing plan, since we can achieve only what we can measure. In order to measure the performances achieved through the marketing plan, we need to constantly monitor each previous stage of the plan.
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?
