In Taiwan, most of the software function are tested and confirmed by developers. According to the relevant reports, the cost of testing does not exceed 5% of the entire project budget.

However, the budget of software functional testing has a high proportion of the overall project in foreign countries, even up about 30%. In fact, the issues of software quality have been more concerned in recent years. The failures happen during the software operation, which may cause serious results.

In the early stage of IT industry development, most software programs are relatively simple and test’s requirements are not complicated. It only do the simple check is enough by the developers. But now the IT industry has progressed to a mature period, the system become more precise, and the software programs are more complicated.

In this stage, it will decrease in sales revenue and increase in operating costs if the software didn’t make a strict testing. It also bring legal liability and lead to a decline in the corporate image. In particular, the influence of the financial and telecommunications systems covers the entire country. The risks spread widely, which will make very serious and harmful results.
