A fresh look at the evolution of IT and Enterprise Software
Much has been written lately about traditional enterprise applications essentially being data entry “forms” and reporting structures, which are implemented to support desirable business processes and practices. It is surely a very complex set of structures, and it takes a very large number of professionals to design, maintain and upgrade these structures to ensure proper functionality, security, availability and performance for a very large number of customers. The most important reason for the rise of the Enterprise Application Software industry was economy of scale. Only 30 years ago all business applications were internally developed by a company’s IT organizations or contractors, with one exception of a General Ledger application available from McCormick & Dodge. The supply of qualified professionals was outstripped by the demand for software by a very wide margin.
