Firms that are successful in marketing invariably start with a marketing plan. Large companies have plans with hundreds of pages; small companies can get by with a half-dozen sheets. Put your marketing plan in a three-ring binder. Refer to it at least quarterly, but better yet monthly. Leave a tab for putting in monthly reports on sales/manufacturing; this will allow you to track performance as you follow the plan.
The results of marketing planning focus on the consumer. This can lead to competitive advantage through lower prices than competitors for the same benefits or uniqueness of benefits that can cover a high price.
