of methodology and process called Strategic Early Warning (SEW), first introduced by Gilad, followed by Steven Shaker and Victor Richardson, Alessandro Comai and Joaquin Tena, and others. According to Gilad, 20% of the work of competitive intelligence practitioners should be dedicated to strategic early identification of weak signals within a SEW framework. Tactical Intelligence: the focus is on providing information designed to improve shorter-term decisions, most often related with the intent of growing market share or revenues. Generally, it is the type of information that a person would need to support the sales process in an organization. It investigates various aspects of a product/product line marketing. With the right amount of information, organizations can avoid unpleasant surprises by anticipating competitors' moves and decreasing response time. Examples of competitive intelligence research is evident in daily newspapers, such as The Wall Street Journal, Business Week, and Fortune. Major airlines change hundreds of fares daily in response to competitors' tactics. They use information to plan their own marketing, pricing, and production strategies. Resources, such as the Internet, have made gathering information on competitors easy. Analysts can discover future trends and market requirements. However, competitive intelligence is much more than this, as the ultimate aim is to lead to competitive advantage. As the Internet is mostly public domain material, information gathered is less likely to result in insights that will be unique to the company. There is a risk that information gathered from the Internet will be misinformation and mislead users, so competitive intelligence researchers are often wary of using such information. As a result, although the Internet is viewed as a key source, most CI professionals should spend their time and budget gathering intelligence using primary research—networking with industry experts, from trade shows and conferences, from their own customers and suppliers, and so on. Where the Internet is used, it is to gather sources for primary research as well as information on what the company says about itself and its online presence (in the form of links to other companies, its strategy regarding search engines and online advertising, mentions in discussion forums and on blogs, etc.). Online subscription databases and news aggregation sources, which have simplified the secondary source collection process, are also used.
