One of the most important information resources you'll find is the SBA. The SBA was created by Congress in 1953 to help American entrepreneurs start, run, and grow successful small enterprises. Today there are SBA offices in every state, the District of Columbia, the U.S. Virgin Islands, Puerto Rico, and Guam. Among the services offered by the SBA are financial assistance, counseling services through Small Business Development Centers (SBDCs), management assistance through programs like SCORE, and low-cost publications. The counselors at SCORE can provide you with free consultation on what type of research you need to gather and where you can obtain that information. They may also be able to suggest other means of gathering the information from primary sources. SBDCs generally have extensive business libraries with lots of secondary sources for you to review.
When conducting primary research, you can gather two basic types of information: exploratory or specific. Exploratory research is open-ended, helps you define a specific problem, and usually involves detailed, unstructured interviews in which lengthy answers are solicited from a small group of respondents. Specific research, on the other hand, is precise in scope and is used to solve a problem that exploratory research has identified. Interviews are structured and formal in approach. Of the two, specific research is the more expensive.
