Reliability engineering

properly managed and controlled in order to produce information that satisfies the seven criteria: effectiveness, efficiency, confidentiality, integrity, availability, compliance and reliability. These IT processes are grouped into the following four management activities or domains (Romney & Steinbart, 2012). 1. Plan and Organize (PO), 2. Acquire and Implement (AI), 3. Deliver and Support (DS), and 4. Monitor and Evaluate (ME) Management should develop a plan to organize information resources to provide the information it needs. Then authorizes and oversees efforts to acquire the desired functionality or technology solutions. Management also performs a number of activities to insure that the resulting system actually delivers the desired information. Finally, there is a need for constant monitoring and evaluation of performance against established criteria. Besides management’s responsibility to manage and control over IT, management is also responsible for the security and system reliability of the entire accounting information system (AIS). This is because security is primarily a management issue, not a technology issue. The accuracy of an organization’s financial statements depends upon the reliability of its information systems. And information security is the foundation for system reliability. Therefore, information security is first and foremost is a management issue, not an information technology issue. In other words, management plays very crucial roles in…

A new way to think about institutions When we think of institutions, we often think about the positives associated and how institutions can help people. However, despite what we often think, institutions can have a negative effect on individuals. Our society relies heavily on institutions, particularly the medical and educational institutions, however they often fail us, and as a result, negatively impact individuals. This is highlighted in ‘Whose life is it anyway?’, image 1 and the tragic…

People fail every day. People can fail in a test, work assignment, or a promise. Failure exposes that people are not perfect beings; they are imperfect beings trying to act perfectly. This does not mean success is never attainable for a human, but success relies on the actions failure provides. People never strive to fail; otherwise, people will never start their projects. True failure is the outcome of trying, but missing the minimal goal set as the standard. False failure is slothfulness and…

The main goal of every person is to succeed, right? But true success does not come without failure. Success takes hard work, intelligence, humility, and failure leads to all three of these things. Money is to the root of all evil as failure is to the root of all true success. You must first fail in order to succeed. Failure helps you find the ingredients that are essential to succeeding. Failure is a much better teacher than success, because failure teaches success. True success is not…

2. PRELIMINARIES The research efforts that proposed for the connectivity and coverage issues in WSNs are based upon a lot of theories and assumptions. The basic concepts of connectivity and coverage have an essential role in understanding this issue. In this section, we describe the notions of connectivity and coverage, the category of sensor nodes, sensing models and communication models. 2.1. Connectivity and coverage The objective of deploying a WSN is to keep the FoI under strict…

Introduction This is quality plan for a ruggedized computer system to be used in Tamar lifeboat. This system consists of CPU, screen, keyboard and mouse. It uses methods such as quality function deployment (QFD), failure mode effects analysis (FMEA), reliability analysis, quality standards, ergonomics and redundancy to establish the quality of the system. Furthermore, it seeks to establish if the system fulfils the requirements of the customers. Customer Specifications The customer requires…

The fear of failure is not a universally positive motivator. In some cases it is neither positive nor a motivator. Failure may be described as the eventual and inevitable by-product of the expenditure of efforts to achieve success. A fear of failure has never been anything but an abstract to me, because I do not embrace failure as an acceptable outcome. Success may be attained by researching methods to achieve an action or by avoiding problems through observing failures of other people. In…

They say that the sweetest victory is the one that’s most difficult. I didn’t believe defeat was necessary to succeed in life. I thought that if we failed, we failed. We can’t do anything more to overcome our failures. Over the years I’ve learned that failure is just a stepping stone towards success. I learned that we must drive, dig deeper, and have a lot of determination to reach our goals in life. We will have those people in our lives telling us, “It’s impossible.” or “You might fail, and…

English was always my favorite subject, and I loved reading. But even though I was good at English I truly lacked having writing skills. My noteworthy literacy experience was when I passed the Grade 8 Writing Assessment test after failing it the first time. This experience gave me the fortitude to practice on my writing skills and it actually motivated me to write stories and essays for school with no hesitation. When reading the different literacy narratives, I felt Nichols’s essay was…

What have I learned about failure? I believe there is much to learn from failure and much can be gained by failing. I have learned that we should look at the bright side of failure. Once someone starts looking at failure on the bright side and considering the positives that come out of “failures” they can successfully live a more joy filled life. Now I’m not claiming that once someone looks on the bright side of failures they will automatically become happy all the time and all their problems…
