Decision-Making Styles and Their Affect on Information Systems
The decision-making styles of an international business can have a significant impact on the design of information systems that support decision-making. Depending on the style, the decision support system (DSS) can be centered on individualized decision making or group decision making. There are different requirements needed in a DSS that supports individual decision making and group decision making.
A decision support system centered on individualized decision making will contain software that pertains to the needs of an individual. The DSS will analyze the data from a database and provide the results to the decision maker. The software used for individual decisions would be catered around an individual. A decision support system is often developed using general software that is adapted for a specific decision, but more complex and sophisticated software is available (Nickerson, 2001, p. 350). If the international business is centered on the individual decision style than the decision support system would probable be used on a personal computer, but could also use a network or multi-user computer.

The Information Security Management System
Information security is now too important to be left to the IT department. This is because information security is now a business-level issue:
Information is the lifeblood of any business today. Anything that is of value inside the organization will be of value to someone outside it. The board is responsible for ensuring that critical information, and the technology that houses and process it, are secure.
Legislation and regulation is a governance issue. In the UK, the TurnBull Report clearly identifies the need for boards to control risk to information and information systems. Data protection, privacy, computer misuse and other regulations, different in different jurisdictions, are a boardroom issue. Banks and financial sector organizations are subject to the requirements of the Bank of International Settlements ( BIS ) and the Basle 2 framework, which includes information and IT risk.
