Generally, companies are broken down into four levels of hierarchy, the corporate, the division, the business unit and the product level. The overall plan of the company is designed at a corporate level. As part of this planning, each resource is allocated to each division of the company. Next, division level planning allocates resources to each business unit of the company. In addition, business unit planning designs a strategic plan for each business area, which determines each of the marketing objectives/goals, strategies and tactics, that have to be consistent with the overall strategic plan.
But, I don't specifically mean my own Marketing Plan S6PEC Framework because there are so many versions and gurus out there that can give you the benefit of marketing plan. Of course I am going to say mine is a lot better because it's a practical and practitioner's guide. Other than being a consultant, I also have performed marketing manager role, entrepreneur role, business manager role, investor and student of entrepreneurship (during my MBA!). But that's not my main point. My main point is for you to have a marketing plan to guide your business. Which one? Well it is up to you!
