Download file to see previous pages The Boeing 777 is one of the most successful commercial airplanes made in the industry. The design process started in 1990 and the first plane was delivered in 1995, a remarkably short design period for a complex engineering product such as an airplane. Though the plane was initially designed for a production run of 300 planes, as of August 2013, over 1100 of these wide-body airlines had been delivered. Airlines continue to order these planes 17 years after the first production and the current production rate is 100 a year (Tinseth, Randy, 2013). The aircraft has also had an unblemished safety record and even the crash of the Asiana Airlines plane at San Francisco airport in July 2013 has been attributed to pilot error.
The aircraft industry design process has been described as “design- mockup- rework-prototype-test-revise-produce-test-revise-produce-test” cycle (Snyder, Charles, R., et al, 1998, p34). Boeing 777 design process was dramatically different from earlier practice in the airline industry.
Wolf L. Glende, the Chief Engineer – Systems of the Boeing 777 programme says that the plane was conceived as a model urgently needed to fill the gap between the 747 and the 767. The design target was a plane that could carry 300 and 500 passengers over distances up to 7500 nautical miles at a cruise speed of 0.84 much. The Boeing 777 was the first commercial airplane designed with active participation from its customers. Boeing worked with eight major airlines from the US, Europe and South East Asia to configure the plane they preferred (Glende, Wolf, L., p 5-2).
One key objective was to reduce by at least 50% the change, error and rework that is typical of large engineering system design projects. These objectives were achieved by adoption of certain core processes discussed below (Glende, Wolf, L., p 5-3).
Design of a large airplane involves large teams, employed by different organizations and at various locations. Design activities tend to be done in series with results “thrown over the fence” with incomplete communication. The job specialization of each time makes for incomplete understanding and inter-organization rivalry.
For the 777, Boeing created multi-functional Design/Build Teams (DBT) for each major subsystem of the airplane such as Structures, Avionics, Mechanical/Hydraulics, Propulsion and Payload.  ...Download file to see next pagesRead More

...of hers. One of those foundation theories was Maslow's hierarchy of needs. Modeling is gaining an understanding of the clients world from the clients perspective. It assumes that all humans want to interact with others and quality holistic care is one of the goals. The propositions are the degree to which development tasks are resolved and is dependent on the degree to which human needs are satisfied and the ability to cope is directly related to the level of need satisfaction. It enhances the nurses ability to understand the worldview of adolescents and to use this gained understanding to design health education programs that address the adolescents development needs (Bray, 2005).

The study will therefore involve four parts of study which will look at the actual delays, causes of these delays, analysis of the problem experienced, how to avoid such situations in the future, how to limit the delays and finally make recommendations on the making of complex technological components in future . The delays The first roll out of the Boeing was supposed to be on July 2007; however, at the set time, the manufacturer released a statement stating that the designated launch of the complete plane would not take place at that time. The reason for this was given to be that some...

...coupling, seamless interfaces, and platform for simple and interrelated pieces are characteristics of robust software architecture (Ulrich & Stephen, 2004). Software architecture is not a low-level design that takes care of the data model, although it uses them for defining signature of interfaces. Although it applies hardware configuration system for assessing performance and reliability of software, software and hardware architecture is different. Benefits of Layered Architecture based on Example of Linux Operating System Linux operating system has a kernel at the core of operating system that provides access to the internal resources of hardware such as memory, CPU...

...Boeing Answer one The company should use all the communicating models, which ensure confidentiality, synchronization, accuracy or anonymity (N, 2013). These models use their own ideal functionality whereby they receive a message as input and eventually extract the data as a more reliable production (N, 2013). Some of these mechanisms from the UC include, an ideal authenticated channel, which transfers messages in a secure path (N, 2013). An ideal secure channel is the next it only outputs the name of the sender to the recipient (N, 2013). More sophisticated channels are recommendable such as the ideal anonymous channel that does not reveal the identity...
