Marketing Research will be the first component for your marketing plan. You may be doing this in house or you may elect to hire a top marketing agency, a marketing consultant, or maybe a specific marketing research firm. You need to obtain and capture all data about your business along with your products and services to help you properly facilitate any potential marketing problems. You may also be able to get some marketing data from an industry trade association or from other businesses within your specific industry.
Imagine if you can do all these and manage all these in a marketing plan? Systematic, organized, well thought, innovative and captured all your pertinent business information, don't you find having a marketing plan is useful for your business?
