An information technology (IT) solution is a set of related software programs and/or services that are sold as a single package. IT vendors, service providers and value-added resellers (VARs) market their software suites and service bundles under the label solution to promote the idea that purchasing the product will help the customer successfully solve a problem or deal with a complicated situation.
Many vendors, software developers, in particular, refer to all of their individual products as software solutions. For example, a vendor may call its antivirus software a solution because it helps to solve a particular problem.
In a stricter sense, however, an IT solution is an aggregation of products and services, as opposed to a single, discrete product. To accurately be called a solution, therefore, the antivirus software should be bundled with related products, such as a spam filter or backup service.
