How can human error affect system reliability, and what measures can mitigate i

A safety-critical system is one whose failure or misuse may cause human injury or death.Given that an EHR system can be considered to be such a system, which set of tasks associated with software implementation deserve special attention by the Midwest Hospital project team?   a. Train end users, perform user acceptance testing, and provide for ongoing end-user support and training.     b. Conduct an alpha and beta test, perform a direct conversion to start up the new system, and apply the Lewin and Schein three-stage model for implementing the new system to ensure that appropriate changes are made to people, structure, and tasks affected by the new system.     c. Allow sufficient time for site preparation, perform a direct conversion from the old system to the new system, and employ the technology acceptance model to lead to better attitudes about the use of the new system.     d. Perform thorough unit testing, conduct frequent system reviews to…

CEO John Spychalski is concerned about a problem that has existed at CBN railroad for almost 20 years now. The continuous problem has been that the locomotives used by the company are not very reliable. Even with prior decisions to resolve the problem, there still has not been a change in the reliability of these locomotives. Between 2013 and 2014, 155 new locomotives were purchased and one of CBN's repair shops was reno- vated. The renovated shop has been very inefficient. Spychalski estimated that the shop would complete 300 overhauls on a yearly basis, but instead it has only managed to com- plete an average of 160 overhauls per year. The company has also been doing a poor job servicing customers (that is, providing equipment). CBN has averaged only 87 to 88 percent equipment availability, compared to other railroads with availability figures greater than 90 percent. Increased business in the rail industry has been a reason for trying to reduce the time used for repairing the…

What is measurement reliability? How do we assess it (give one method) and what can we do to improve reliability?

What are the key factors that can affect system reliability, and how can they be mitigated in a production environment?

Differentiate between a cause-and-effect relationship between the following ideas as they apply to system development.Failures, mistakes, and flaws all fall under this category.

What is the role of the end-user in system design?

Hi, I need help with part B of this Operations Management problem. Thank you!

The annual operating costs of Machine A are $2,000. The machine will perform satisfactorily over the next five years and has an estimated market value (MV) of $3,000 at the end of its useful life. A salesperson for another company is offering a replacement, Machine B, for $14,000, with a MV of $1,400 after five years. Annual operating costs for Machine B will only be $1,500. It is believed that $10,000 could be obtained for the old machine A if it were sold now. If the before-tax MARR is 10% per year, determine whether the old machine A should be replaced by the new machine B.
