The Impact of Decision-Making on Information System Dependability

As information technology has spread into all kinds of systems, vulnerabilities in critical infrastructure have increased. Reasons for failing systems vary from the technical issues of new technology to the human aspects. Developing dependable complex and interconnected systems requires cooperation, rationality and analytical methods. Software development is mainly brainwork, and thus decision-making presumably has a great affect to software quality. In this research we studied types of information system failures and the state of decision-making in software industry. We found out that vulnerabilities in systems are partly caused by incompetent decision-making.
