Reliable Design Principles
Question One
The three principles of a reliable design include failure prevention, reducing harm from failures, and learning from failures. The principles have been applied in enhancing patient safety and quality of healthcare in the healthcare organizations like in Mercy Hospital St. Louis. They have been applied in preventing a system failure involving medication errors in which a patient gets a wrong treatment or dose of the correct treatment. Thus, time-outs have been included in the operating rooms in which includes the surgeon, patient, and the nursing personnel to confirm the identity, the procedure and the area to be operated to prevent and reduce the harm of errors. The hospital also learns from the failure by installing a backup oxygen delivery, use of longitudinal data, and checklists and identification are also regularly checked for continuous patient safety.
Question Two
Teamwork promotes the prevention of failure because the error diagnosis in the medication is an active team-based process which requires health care professionals with appropriate skills, knowledge, and resources for the diagnostic procedure. Teamwork would enable doctors to involve patients and to reduce failures and their associated harm in data collection, incorporation, and interpretation. This function of teamwork further permits faster and more precise communication of information to clients and other professional or provider, which maximizes the possibilities of accurate and timely failure or error recognition and minimization of the harms.

Teamwork can, therefore, help develop a framework for avoiding future system failures through the sharing of ideas with and support from different professionals and patients in the hospital and enhance creativity in redesigning the system for preventing future failures.
Question Three
If the zoo waited to redesign its systems until an actual failure, there would be adverse consequences, which would be challenging to diagnose, minimize, or stop. For example, if the failure to redesign the system would expose the personnel to the venomous snakes that would bite an employee and cause death. The healthcare systems are more often reactive with regards to the safety issues because most of the risk events that occur in the majority of these systems are acted upon after they have actually occurred. The proactive approaches are either not efficient/applicable or are not followed/implemented by the workforce.
Question Four
In the zoo, an example of a latent error that was noted is the untimely communication and inadequate observation from managers. The latent errors in the health care system include the dysfunctional equipment or system, ineffective communication, ineffective training, inadequate suspension, and poor equipment and plant design.
