Which of the following are examples of system failures?

The identification of IT failure and process breakdown as examples of system failures is accurate because both are direct indicators of inadequacies within organizational systems. System failures occur when established processes or technologies do not function as intended, leading to operational disruptions or ineffective results.

IT failure can exemplify a failure in the technological infrastructure that supports a company’s operations. Such failures might include system outages, software bugs, or security breaches, all of which can severely hinder an organization's ability to function efficiently. Meanwhile, process breakdown refers to failures in established procedures or workflows, which may result from a variety of issues, including lack of training, poor communications, or outdated practices. Both forms of failure have significant implications for risk management as they can lead to financial losses, reputation damage, and an overall loss of trust from clients and stakeholders.

The other choices either represent factors that can lead to system improvements or are not directly related to system failures. For example, employee turnover and market expansion refer to external and human resource dynamics, while consistent productivity levels and improved sales figures indicate stability and growth rather than dysfunctions within systems. Therefore, option B is the only one that directly captures instances of system failures.
