Answer Each These Questions In A Paragraph With At Least Five Sentence

1. Provide a citation for each answer. Give an example from the book where insufficient testing was a factor in a program error or system failure. What was one cause in the delay in the completing of the Denver Airport. Why didn't the healthcare.gov website work at first?

Insufficient testing of software often leads to critical failures, as exemplified by the Therac-25 radiation machine, where inadequate validation and testing resulted in deadly overdoses of radiation (Leveson & Turner, 1993). This underscores the importance of comprehensive testing to identify potential errors before a system is deployed. The Denver Airport experienced delays primarily due to mismanagement and poor project planning, including issues with infrastructure readiness and coordination problems, which collectively prolonged the completion timeline (Gunn, 1994). Healthcare.gov initially failed due to a combination of technical glitches, underestimating the complexity of integrating various federal health data systems, and insufficient testing prior to launch (Kaiser Health News, 2013). These issues highlight how inadequate preparation and testing can lead to system failures and project delays.

2. What is one characteristic of high reliability organizations? Describe the potential risks of alert fatigue in EHR systems.

High reliability organizations (HROs) are characterized by a preoccupation with failure, meaning they continuously anticipate and address potential errors to prevent accidents (Roberts, 1990). They foster a culture of vigilance and emphasize the importance of sensitivity to operations. Alert fatigue in Electronic Health Record (EHR) systems presents significant risks because clinicians become desensitized to alerts after frequent false alarms, which can lead to critical warnings being ignored (Ancker et al., 2017). This desensitization increases the potential for medication errors, missed diagnoses, and patient harm. Overcoming alert fatigue requires designing smarter, context-aware alerts that minimize unnecessary interruptions while maintaining safety.

3. What were 2 common factors in both the Therac-25 case and the space shuttle disaster?

Two common factors in both the Therac-25 incident and the space shuttle disaster were overconfidence in technology and breakdowns in communication. In the Therac-25 case, developers trusted the software to be infallible without sufficient testing or validation, neglecting potential human or system errors (Leveson & Turner, 1993). Similarly, the Challenger disaster resulted partly from poor communication and organizational failures where engineers' concerns about the O-rings' performance were ignored, leading to the catastrophe (Vaughan, 1996). Both cases highlight how overreliance on technology and inadequate communication can lead to catastrophic failures, emphasizing the need for rigorous safety protocols and open communication channels.

4. What does design for failure mean?

Design for failure is a proactive engineering approach that involves planning and designing systems to gracefully handle faults and failures, minimizing their impact on overall operation. This concept ensures that even if a component fails, the system continues to operate safely or fails in a controlled manner, allowing timely detection and repair (Leveson, 2011). For example, aircraft systems are designed with redundancies so that a failure in one component doesn't endanger the entire flight. This philosophy aims to enhance system resilience, improve safety, and reduce the risk of catastrophic failures, emphasizing that failure is an expected part of complex systems and must be managed effectively (Vliet, 2008).
