As part of your product/service feasibility analysis, you should conduct primary research with potential customers in order to assess the desirability of your new product/service idea, as well as evidence of likely demand. Examples of such research include concept tests and buying intention surveys.
Step 2: Supplement Your Primary Research With Secondary Research
You can find additional evidence of likely demand by looking for information about the new product or service in business, industry, or news sources available from Library Databases or other online sources.
Another method of assessing the demand for a product or service is to find articles written about the problem your proposed product or service is trying to solve. These articles may have been published online or in newspapers, business journals, or industry / trade magazines*
Find scholarly journals, books, trade publications, dissertations, working papers, company, industry and market research reports, newspapers, business cases, ebooks, streaming video, and other sources relevant to research in business and economics.
Includes the ABI/Inform Collection, J. P. Morgan Research, the Entrepreneurship Database, the Business Video Database, the Accounting, Tax & Banking Collection, the Asian & European Business Collection, and the Business Market Research Collection. More Information.
Google News Search can be an effective tool for identifying the latest news stories from a wide variety of news sources. However, most publications are not freely available online, so your best bet is to look for the fulltext articles in one or more of the Library's News or Business Databases.
