3.CONCLUSION * Key Quality Character Setting

, LENOVO performs better, however, the difficulty for improvement is relatively high. Therefore, it is better to develop the attributes later rather than now

╳√╳ √√ √

, The amount of memory of SONY and LENOVO are equal; correspondingly we can take several steps to target a competitive advantage

,

SONY has a patent for using light material and in contrast, LENOVO does not. As a result, SONY has an advantage. However, there are also some shortcomings, for instance: reliability. Therefore .we should learn from the other competitors in order to improve our products.

,

When it comes to the size, SONY has some advantages, whereas size is the attribute which is of the lowest technological difficulty. Hence in order to beat the competitors in the market, SONY should strive for continuous innovation in the technology field.

, The thickness of SONY is among the best in the opening market; however it is difficult for development. Consequently ir would better be delayed the technological improvement

, The most important one is hard disk, there is much potential for improvement and therefore a lot of attention should be paid to it.
