Effective business management is based on the use of relevant information. To be useful, information must be available in the right quantity, quality, place and time. In an enterprise, this function is often provided by an information system. The enterprise information system is one of the key factors for the competitiveness of not only large and multinational companies but also small and medium-sized enterprises. The information system gives the management of the enterprise access to various output reports and statistics, which are a source of information needed for flexible decision-making. However, flexibility requires timeliness, regularity and speed. Timeliness is understood as the actual input of information, regularity is understood as the flow of information at regular intervals to give an idea of developments in a given area, and speed means the time in which the necessary information can be obtained. However, in addition to flexible decision-making, the management has also set a long-term goal for which the most valuable information is also important. In order to be competitive today, a company must be able to react flexibly to changes in the external environment in response to customer demands and competitor behaviour. In general, there are two ways to adapt to these changes. The first is short-term, one-off or transitional measures. The second option is long-term action in the form of changes in the company's processes, its structure, or intervention in the corporate culture. An example of such a change can be the introduction of an enterprise-wide information system [Gala 2009].
