Enterprise as work means communities and organizations.
An enterprise application is the phrase used to describe applications (or software) that a business would use to assist the organization in solving enterprise problems. When the word "enterprise" is combined with "application," it usually refers to a software platform that is too large and too complex for individual or small business use.
Software designed to integrate all aspects of a firm's operations and processes such as accounting, finance, human resources, inventory control, manufacturing, marketing, sales, and distribution, and resource planning. Advanced enterprise applications provide linkages with customers, business partners, and suppliers.
