E-Business Systems

Consider costs of a system in light of the five components: costs to buy and maintain the hardware; costs to develop or acquire licenses to the software programs and costs to maintain them; costs to design databases and fill them with data; costs of developing procedures and keeping them current; and finally, human costs both to develop and use the system.

a. Over the lifetime of a system, many experts believe that the single most expensive component is people. Does this belief seem logical to you? Explain why you agree or disagree

A system consists of many components working together to achieve a common objectives and goals. An information system generally consists of five components; there are people, procedure, data, software and hardware. When we study these components carefully the only component that is rational and that can act on its own is people. People invent hardware's develops software from data write procedures, so it is obvious that the people are the most expensive component of an information system. On the other hand we can buy a hardware such as a computer $ 1500 and a software for a similar price. And once we buy you own it. Where as people cannot be bought and we will have to spend thousands of dollars to hire people with expertise and experience. An accuracy of a machine and a software depends on how accurately information are fed, A slight mistake in the feeding the information will result disasters consequences. Human accuracy is what decides the success of any system. Therefore I do agree with the above logic

b.Consider a poorly developed system that does not meet its defined requirements. The needs of the business do not go away, but they do not conform themselves to the characteristics of the poorly built system. Therefore, something must give. Which component picks up the slack when the hardware and software programs do not work correctly? What does this say about the cost of a poorly designed system? Consider both direct money costs as well as intangible personnel costs.

We should be extra courteous in developing any system, so that it should function accurately and must be reliable to fit for its purpose. Any slight mistake made by human in forming a system will result severe consequences. A poorly developed system can never meet its definite requirement and the need of the business cannot be satisfied with it. Therefore its important that system should be developed with accuracy, dedication and reliability as companies spend thousand of dollars to purchase and maintain systems which are capable of handling day to day activities. Let's consider a point of sale (POS) terminal. If the particular information systems used in these wonderful machines do not function accurately it can result losses amounting thousands of dollars and also a reputation of the company that uses these machines will be gone in a fraction of a second. We know that companies spent thousands of dollars on these machines and the time, hard work and dedication made by them is immense, so a slight mistake in the system resulted in pecuniary and non pecuniary losses that are huge and will take lots of time to manage and overcome these loses. In addition the reputation of the company has to be built from zero. These all results due to a poorly developed system.

Now we know that it is a responsibility of people to develop accurate and reliable system, if not the loss that cause will be irreparable.
