buy custom The Impacts of Changing Software Requirements essay The issue of new changes to be introduced into the system should be addressed during the earlier stages than at the late stages of the software development life circle. The later a change is addressed, the greater the cost, risk and duration of the project. The first scenario depicts some stakeholders (the project team leaders) as being part of the source of the feature creep introduction. The company signs an agreement that was not initially part of the deal. This issue has both its advantages and disadvantages. Starting with the advantages, the company has decided to adopt a framework that is in line with the ADA and section 508. This is a great deal as it provides for more user needs and standards. The feature creep in this case helps achieve the business goal as well as the customer needs. It as well aids in advancing the project to fit into its ideal problem solving state. Based on various techniques, a team through their leader can cope up with the changes and come up with a strategy that will allow them to deliver the software according to the new requirements. First of all, on the start of the project, the team has a mandate to accept that feature creep is part of the project so, prepare in advance. Secondly, they can commit enough time to the requirements elicitation. While performing the intensve requirements analysis, they should also consider the boundaries to changes and when they can be made. Meanwhile, the team should remain task-oriented and consider the customer as right while taking on a lot of research before deciding to commit. On the other hand, the feature creep has negative impacts on the developing team. First of all, additional costs have to be incurred. The developers possibly have to fix the new requirements beginning with the point of integration of the new idea. The project takes more time than the initially decided time and more risks have to be incurred. This leads to delay in the project delivery an altered project milestone results. Most programming languages have a steep learning overhead hence new suggestions would put everything on hold. This leads into the team members frustration especially in the case where they were not consulted. It is therefore necessary to have the project team aware of any consultations and their directions. In the second scenario, the Contents Management System, a scope creep is introduced into the system. The project is now meant to handle more Operating Systems based on a web platform. The result of this is additional development expenses and time introduced into the system. In addition, the complexity of the system becomes a question. Before anything can be done with the suggestions that have been made, it is necessary to carry out a change analysis. The requirements must be considered so that the product satisfies the clients needs. Some changes may be critical to a system so, they must be included whereas some are optional hence can be included in a version of the software. Any alternative that is taken has an impact on the design. First, there is a time taken to decide on which option to take. Secondly, there are new risks that are introduced into the projects design phase. The design may be produced in a manner that doesnt satisfy the customers need. Lastly, the cost of the whole project goes higher than the initially intended costs. This is due to more resources that need to be allocated to the projects in order to accomplish the new mission. Nevertheless, the second scenario leaves the system developers with a decision to make on whether to take the change defer it or reject it. If the developers decide on a progressive application upgrading, then they can start off with the initial projects and implements the customers needs. However, rejecting the change is the least expected decision. A project that fails to address the change in the requirements and quantifying the effects of the changes normally fails.

greetings Essays

greetings Essays greetings Essay greetings Essay Greetings United States of America Both men and women usually smile and shake hands when greeting. The American handshake is usually firm. Good friends and relatives may embrace when they meet, especially after a long absence. In casual situations, people may wave rather than shake hands. Friends also wave to each other at a distance. Americans may greet strangers on the street by saying Hello or Good morning (in Spanish, Hola or Buenos dias), although they may pass without any greeting. Among young people, casual verbal greetings or hand-slapping and fist-bumping gestures are common. Except in formal situations, people who are acquainted generally address one another by given name. Combining a title (Mr. , Ms. , Dr. , for example) with a family name shows respect. When greeting someone for the first time, Americans commonly say Nice to meet you. A simple Hello or Hi is also common. Regional variations exist, such as Howdy (Hi) in some southern regions or Aloha (Hello) in Hawaii. Friends often greet each other with How are you? and respond Fine, thanks. Americans do not usually expect any further answer to the question. American greetings are generally quite informal. This is not intended to show lack of respect, but rather a manifestation of the American belief that everyone is equal. Although it is expected in business situations, some Americans do not shake hands at social events. Instead, they may greet you with a casual Hello or How are you? or even Just HI. In larger groups, many may not greet you at all. In social situations, Americans rarely shake hands upon leaving. The only proper answers to the greetings How do you do? How are you? or How are you doing? re Fine, Great, or Very well, thank you. This is not a request for information about your well-being; it is simply a pleasantry. See you later is Just an expression. People say this even if they never plan to see you again. When saying good-bye, Americans may say Well have to get together or Lets do lunch. This is simply a friendly gesture. Unless your American colleague specifies a time and date, dont expect an invitation. If you wa nt to have lunch, you should take the initiative to schedule it. Stand while being introduced. : Only the elderly, the ill and physically unable persons remain seated while greeting or being introduced. It is good to include some information about a person you are introducing. Example: Susan Olson, Id like you to meet John Harmon. He designed the brochure we are using for this campaign. Use professional titles when you are introducing people to each other. Example: Judge Susan Olson, meet Dr. John Harmon. If you are introducing yourself, do not use your professional title. Handshakes are usually brief. Light handshakes are considered distasteful. Use a firm grip. Eye contact is important when shaking someones hand. There are many different ways people greet one another on the street, in the home, or in business situations throughout America. Understanding the appropriate use of the American greeting will make any situation comfortable as well as make a good impression on those in present company. Informal greetings include words such as Hi and Hey. Although other acknowledgments such as How do you do? or Im it doesnt necessarily mean they want to hear about your health conditions, they are imply using it as a greeting. A common, somewhat formal response is Im fine, thank you. Though less formal responses, if appropriate, can be as casual as Good! or even 0K. Americans will usually say Good-bye or simply Bye when bidding someone farewell at the time of departure. More expressive salutations include Have a nice day, It was nice seeing you, or See you later. Another simple, but greatly appreciated greeting or acknowledgment, which is universally recognized is a smile in combination with direct eye contact. Good riends, family members, or people in a romantic relationship might give each other a hug or even kiss upon meeting one another or when saying good-bye. This kind of greeting is however, reserved for people who know each other very well and share a very close relationship. Americans often shake hands when being introduced to someone. In more informal situations it is common for people not to shake hands unless a long period of time has elapsed and the people feel comfortable with each other and their mutual friendship. However, in formal business situations people ost often greet each other with a handshake every time they meet or say good-bye. As a gesture of friendliness, if a person offers you his hand, you should shake it. It could be considered rude if one didnt. Many times men are the only ones who shake hands in a mixed group. It is customary for a man to shake a womans hand only if she offers her hand first, though this is somewhat of an old-fashioned custom and today offering a hand to a woman is accepted, if not expected. An appropriate handshake should be firm and brief. It will be respected, in almost every social or professional situation when greeting or departing the presence of someone. On the other hand, a soft or weak handshake is viewed negatively by most people throughout the United States and is commonly thought of or indicates that the person might be insecure. Remember that social customs might vary in different parts of the country and also between younger and older generations of people, so it is always a good idea to observe the actions of others, the surrounding situation and whether the situation is formal or informal.

Case study on the design of a contemporary Civil Engineering project Essay - 1

Case study on the design of a contemporary Civil Engineering project - Essay Example The bridge is a natural expression of structural engineering and architecture but a city center footbridge is equally about people and the environment; in short a piece of public architecture. The bridge gives the pedestrians unique views of London, free from traffic and high above the Thames. In September 1996, a competition was organized by a London-based newspaper the Financial Times and London Borough of Southwark to design a new Footbridge across the River Thames. The idea behind the competition was to get the best design in every aspect therefore the teams participating in the design were structured to have an engineer, an architect and an artist. More than 200 teams participated and the competition was won by Arup (engineer), Foster (architect) and Sir Anthony Caro (Sculptor). The height restrictions and the view behind the bridge required an innovative design which was provided in the form of a design which included some unusual practices; the suspension design had supporting cables below the deck level. This innovative design was given the name ‘blade of light’ by its designers. The structure of the Millennium Bridge is innovative and complex but it has been designed to achieve an apparent simple form. The design of the Millennium Bridge is based on the following considerations: An evolved support system in which the majority of the bridge stiffness is created by shallow cable profile derived tension. This allows a light bridge deck structure. A modular design in which several structural members and components can be repeated in the structure, thus reducing the fabrication costs. This can also simplify the maintenance after the construction and allows easy execution of the construction phase. The distribution of the forces on the foundations should be such that they do not disturb the existing structures on the north bank and also the foundations of the existing bridges. The aesthetics of the bridge at night were also a big concern and a l ight pipe system illumination was proposed to create a ‘blade of light’ across the river at night. The river traffic analysis is also important while designing a bridge at such a location. A major issue was the provision of planning advice for gaining the necessary approvals to construct a new river crossing in the heart of London. Moreover ways of generating the finances for the bridge were also to be considered while designing the bridge. Superstructure Design The bridge design is a shallow suspension bridge in which the view behind the bridge is facilitated by keeping the suspension cables below the bridge deck. The bridge is supported on two river piers through two groups of four 120mm diameter locked coil cables which span from one bank to the other. The three spans of the bridge have different lengths. The middle span which lies between the two piers is 144m long. The north span is 81m long while the south span is 108m in length. Fabricated steel box sections whic h are known as the transverse arms span between the two
