Information systems are designed so that every financial transaction can be traced. In other words, an audit trail must exist that can establish where each transaction originated and how it was processed.
Aside from financial audits, operational audits are used to evaluate the effectiveness and efficiency of information systems operations, and technological audits verify that information technologies are appropriately chosen, configured, and implemented.

In general, use of Web-based information systems can significantly lower the costs of communication among workers and firms and cost-effectively enhance the coordination of supply chains or webs.

The capability to communicate information efficiently within a firm has led to the deployment of flatter organizational structures with fewer hierarchical layers.
Nevertheless, information systems do not uniformly lead to higher profits. Success depends both on the skill with which information systems are deployed and on their use being combined with other resources of the firm, such as relationships with business partners or superior knowledge in the industrial segment.
The use of information systems has enabled new organizational structures. In particular, so-called virtual organizations have emerged that do not rely on physical offices and standard organizational charts.
Two notable forms of virtual organizations are the network organization and the cluster organization. In a network organization, long-term corporate partners supply goods and services through a central hub firm. Together, a network of relatively small companies can present the appearance of a large corporation.
Indeed, at the core of such an organization may be nothing more than a single entrepreneur supported by only a few employees. Thus, network organization forms a flexible ecosystem of companies, whose formation and work is organized around Web-based information systems.
In a cluster organization, the principal work units are permanent and temporary teams of individuals with complementary skills. Team members, who are often widely dispersed around the globe, are greatly assisted in their work by the use of Web resources, corporate intranets, and collaboration systems.
The role of consumers has changed, empowered by the Web. Instead of being just passive recipients of products, they can actively participate with the producers in the cocreation of value.

The value of virtual worlds and massively multiplayer online games has been created largely by the participants.
The electronic word-of-mouth in the form of reviews and opinions expressed on the Web can make or break products. In sponsored cocreation, companies attract their customers to generate and evaluate ideas, codevelop new products, and promote the existing goods and services.
Virtual customer communities are created online for these purposes. Information systems in the economy and society Along with the global transportation infrastructurenetwork-based information systems have been a factor in the growth of international business and corporations.

Electronic commerce has moved many relationships and transactions among companies and individuals to the Internet and the Web, with the resulting expansion of possibilities and efficiencies. The development of the Internet-based ecosystem—accompanied by the low cost of hardware and telecommunications, the availability of open-source software, and the mass global access to mobile phones—has led to a flowering of entrepreneurial activity and the emergence to prominence and significant market value of numerous firms based on new business models.
Among the examples are electronic auction firms, search engine firms, electronic malls, social network platforms, and online game companies.Learn about viewing organizations as systems in this topic from the Free Management Library.
