Week 8: Design Issues

In the old days, to do experiment to develop an equipment have to use the real equipment. Now, a simulator can be created to simulate the work of the real equipment, and the result can be quite the same as the real one. It is a great advantage cost-wise. For training of pilot simulator not only reduces cost (fuel cost) but also reduces the risk of accident.
The advantage is enhanced by the availability of the program in variety of user interface such as program used in computer can also be used in handphone, PDA.

The code that has been generated for a function need to be communicated to the device that can carry out the function. In order for the communication to work, standard had to be established. In more advanced technology today, the standard created has to be more strict like the XHTML compared to HTML. Example of standard: in computer press alt+F4 usually close a program.

Iterative development is a way of development that build a model, test is and evaluate it. The process is repeated until the result is satisfying. The model build can be smaller than the intended thing, therefore save cost before building the real thing.

Designing a new model is not only designing job by engineer. It involved other task, such as marketing survey, promotion in order for the new innovation to hit the market. Marketing survey is needed, so that the innovation meet the need of customer. A new innovation with very advanced technology that already spent a lot of research fund may not have a good selling if what the technology can do doesnt meet the need of the customer. e.g. fuel cell car is very advanced technology with high efficiency and low pollution, but still people prefer gasoline car since it is cheaper than fuel cell car. Because most people don't care about the pollution generated by their car until there is a law that prohibit the use of gasoline car.

After the technology is developed, the next thing to do is promotion. People have to know what the technology can do, what is its advantage. Like the i-phone, even before the launching of the product, many people want to buy it because they have good introduction of their product.
