The Hi-Tech industry must develop the correct new products by replacing the products that entered decline phase gradually constantly for facing the competition situation of globalization. And they need to create new value for enterprise and could avoid the destiny that enterprises are eliminated. That is to say, it is the key point that enterprises manage continuously forever to only innovate constantly.
The text is appointed by Goldratt (1986)’s “Theory of Constraints”. He uses the system view to solve the problem that every stage for new product development may meet. It can pursue enterprises in the whole optimization of new product development and make enterprises more competitive in globalizing.
Goldratt thinks that the most output will be determined from a weak one segment. And a certain optimization of some segments does not mean the whole system is already optimization. The most serious is, enterprises will be blocked because of the weakest segment in the system. It will make the biggest output of some segments become forming of the biggest dull resource. Because enterprise’s resources is wasted unconsciously. So the marrow of theory is to find out the weakest part from system and improve it first. Then to make it to the greatest efficiency and make other segments fully cooperated in the system. It is purposed to originally restrain the restriction of systematic development from improving.
Because the category of the Hi-Tech industry is very wide, this is limited for studying resources and only can regard case as the target, and address to the construction of new product development model by using the theory of constraints. Through the identification of empirical study, the systematic view emphasized by the theory of constraints can be used to tackle a great deal of problems encountered in whole new product’s development. Beside, we discovery the theory of constraints is useful in enterprise's whole management and administration. It can solve a great deal of problems that enterprises face and also will improve the competitiveness in the globalization market of enterprise.
