Mars Climate Orbiter The Mars Climate Orbiter (formerly the Mars Surveyor '98 Orbiter) was a 338 kilogram (750 lb) robotic space probe launched by NASA on December 11, 1998 to study the Martian climate, atmosphere, surface changes and to act as the communications relay in the Mars Surveyor '98 program, for Mars Polar Lander. However, on September 23, 1999, communication with the spacecraft was lost as the spacecraft went into orbital insertion, due to ground-based computer software which produced output in non-SI units of pound-seconds (lbf×s) instead of the metric units of newton-seconds (N×s) specified in the contract between NASA and Lockheed. The spacecraft encountered Mars on a trajectory that brought it too close to the planet, causing it to pass through the upper atmosphere and disintegrate. Mission background History
Principles of Management 1.1 Figure 7.3 Source: Photograph courtesy of Toyota Motor Sales, USA, Inc. Toyota Motor Corporation (TYO: 7203) has often been referred to as the gold standard of the automotive industry. Who Killed the Virtual Case File? In the early 1990s, Russian mobsters partnered with Italian Mafia families in Newark, N.J., to skim millions of dollars in federal and New Jersey state gasoline and diesel taxes. Special Agent Larry Depew set up an undercover sting operation under the direction of Robert J. Chiaradio, a supervisor at the Federal Bureau of Investigation's Washington, D.C., headquarters. Depew collected reams of evidence from wiretaps, interviews, and financial transactions over the course of two and a half years.
Hierarchical organization Members of hierarchical organizational structures chiefly communicate with their immediate superior and with their immediate subordinates. Structuring organizations in this way is useful partly because it can reduce the communication overhead by limiting information flow; this is also its major limitation. Visualization Therac-25 The Therac-25 was a radiation therapy machine produced by Atomic Energy of Canada Limited (AECL) after the Therac-6 and Therac-20 units (the earlier units had been produced in partnership with CGR of France). It was involved in at least six accidents between 1985 and 1987, in which patients were given massive overdoses of radiation, approximately 100 times the intended dose.:425 These accidents highlighted the dangers of software control of safety-critical systems, and they have become a standard case study in health informatics and software engineering. Problem description The machine offered two modes of radiation therapy:
About Toyota Culture We firmly believe that a group of motivated people can achieve far more than the sum of their individual efforts. As such, everything here revolves around teamwork, which creates a mutual trust and respect that extends across all levels of the organisation. Plus, of course, everyone shares an immense sense of pride in contributing to the manufacture of a superior quality product. Our main priority is to grow and prosper as a company. CIO interview: The Met's Richard Thwaite on its Total Technology IT strategy Following the announcement of a four-year IT strategy for the Metropolitan Police, CIO Richard Thwaite speaks to Computer Weekly about the challenges it faces in getting the business and IT suitably aligned as the force embarks on its Total Technology vision. The Met’s IT has been under intense scrutiny over the past 16 months, following an internal investigation by consultancy Deloitte in October 2012, which stated a “compelling and critical” need for change in the way the force delivers technology. The Deloitte report warned that if the Met did not complete the 100-day plan – including the delivery of the new strategy – it would risk “underachieving and, at worst, could have a destabilising impact” on policing. The London Assembly then conducted an investigation of its own, which led to the Smarter Policing report in August 2013. But the new plan remained unseen nine months later, only being revealed last week. Aligning technology with police goals
Protecting and Safeguarding NASA Information and Information Systems Protecting and Safeguarding NASA Information and Information Systems By Evelyn Davis and Valarie Burks, NASA IT Security Division, OCIO What if this article was the national headline across the United States? Pentium FDIV bug 66 MHz Intel Pentium (sSpec=SX837) with the FDIV bug The error was discovered by Professor Thomas R. Nicely at Lynchburg College, Virginia, USA. Chronology On October 30, 1994, Nicely sent an email describing the error he had discovered in the Pentium floating point unit to various contacts, requesting reports of testing for the flaw on 486-DX4s, Pentiums and Pentium clones. This flaw in the Pentium FPU was quickly verified by other people around the Internet, and became known as the Pentium FDIV bug (FDIV is the x86 assembly language mnemonic for floating-point division).
Problems with Hierarchical Structures Mintzberg’s typology of organizations is a theory that has caught my attention. Over the last years many studies have stated that for companies to be more successful in the modern world, their organizations should make their structures flatter, rather than keep them hierarchical. The reason to this is because of the fact that in the present day and age, information flows so rapidly that there is a need for faster decisions. As we did our mock presentation last week in our Global Strategy course, I would like to base this blog on the company that we chose, Toyota Motor Corporation, and point out an example which reflects how their structure and configuration has brought them problems over the last years. It is important to point out some of the main characteristics of this company in terms of their assets, workforce and etc, in order to classify it into one of Mintzberg’s structures and then to analyze why it has been failing in the past.
Met Police technology use slammed as 'outdated' and 'inefficient' by London Assembly report Crime in London is higher than it should be due to shoddy and out-of-date technology that is being used by the Metropolitan Police Service (MPS). A damning report by the London Assembly’s Budget and Performance Committee, entitled Smart Policing: How the Metropolitan Police Service can make better use of technology, said the force is currently spending a large portion of its budget on keeping technology that dates as far back as the 1970s operational. This is holding it back from embracing new, cutting-edge tools in the fight against crime. Chairman of the assembly committee, John Biggs, said this situation had to change in order to improve policing in the capital. “The Met has been paying over the odds for technology for years – much of which has gone on maintaining a collection of outdated and increasingly inefficient systems put together over the last 40 years. This has got to change," he said.
NPR 2800.1B - Chapter1 Subject: Managing Information Technology Responsible Office: Office of the Chief Information Officer 1.1 Introduction Effectively and efficiently managing, preserving, protecting, and disseminating the information required to achieve, and resulting from, exploration and other NASA missions is vital to mission success. As well, seamless collaboration of the NASA workforce across multiple Centers will be vital in the planning, design, and development of mission-related capabilities and technology in the future. It is imperative that information technology (IT) at NASA be managed in a manner that enables the NASA mission and operating model, now and in the future.
Test Case Format Process impact: This reference page documents the format of test cases and gives tips on writing test cases. You can copy and paste the sample test case into your test-cases.html file. This file itself should not be edited to hold specific test cases. This test case format is suitable for manual system test cases. The test cases should be written in enough detail that they could be given to a new team member who would be able to quickly start to carry out the tests and find defects. Format of test steps
