| Sumario: | This chapter covers the basic concepts of the information systems (IS) field to prepare the reader to quickly approach the book’s other chapters: the Definition of information, the notion of system, and, more particularly, information systems. We also discuss the typology of IS according to the managerial level and decision-making in the IS. Furthermore, we describe information systems applications covering functional areas and focusing on the execution of business processes across the enterprise, including all management levels. We briefly discuss the aspects related to IS security that ensure the protection and integrity of information. We continue our exploration by presenting several metrics, mainly financial, to assess the added value of IS in companies. Next, we present a brief description of a very fashionable approach to make the information system evolve in all coherence, which is the urbanization of IS. We conclude this chapter with some IS challenges focusing on the leading causes of IS implementation’s failure and success. |
