DEVELOPMENT STRATEGIES OVERVIEW Just a few years ago, a typical company either developed software itself, purchased a software package (which might need some modification), or hired consultants or outside resources to perform the work. Today, a company has many more choices, including application service providers, Web- hosted software options, and firms that offer a variety of enterprise-wide software solutions. Selecting the best development path is an important decision that requires companies to consider three key topics: the impact of the Internet, software outsourcing options, and in-house software development alternatives. These topics are reviewed in the following sections.
THE IMPACT OF THE INTERNET The Internet has triggered enormous changes in business methods and operations, and software acquisition is no exception. This section examines a trend that views Software as a Service, the changing marketplace for software, and how Web- based development compares to traditional methods. The section concludes with a description of Internet related trends, including Web 2.0 and cloud computing.
