The information systems function creates and regularly updates a business information model and defines the appropriate systems to optimize the use of this information. This encompasses the development of a corporate data dictionary with the organization’s data syntax rules, data classification scheme and security levels. This process improves the quality of management decision making by making sure that reliable and secure information is provided, and it enables rationalizing information systems resources to appropriately match business strategies. This IT process is also needed to increase accountability for the integrity and security of data and to enhance the effectiveness and control of sharing information across applications and entities.
