在競爭激烈的環境，消費者對市場的偏好變化多端，企業無不絞盡腦汁的開發新產品，期望能滿足消費者的需求。產業進步快速，產品壽命周期越來越短，企業為求生存與發展，新產品的開發就越顯得重要。而在新產品開發案進行中，雖然一切評估及測試都依照原先制定的計劃進行，卻並不是每一個開發案都成功。
  本研究探討新產品在開發過程中，為何經過層層的計劃執行監控及改善後，成功的機率仍然這麼低，是否因不可預期的變數而造成高失敗率？何種非預期變數會對新產品開發案造成影響？
  本研究之問題，以企業的核心競爭力為出發點，研究新產品開發案成功或失敗的原因，探討新產品在開發過程中不可預期的變數對新產品開發案會造成的影響，整理出如何減少新產品開發案因受到不可預期的變數而失敗所造成的損失，並對新產品開發的風險管理提出建議。

In the environment with keen competition as we live now, the consumer’s marker is changeful. To be suit for the consumer’s needs, lots of new products are invented and to be developed as a challenge to all businesses. The industry progresses fast, the product life cycle is short and shorter. As a result, the most important to a business to be survived and developed is how the new products could be created and developed. But, to go on each new project, it is not always success. Even though, the project is followed according to the assessment and the evaluation that plan have made originally. 

This article is going to talk about why the average of success to go on a new project is low even the project has planned and has been corrected and corrected step by step. Is it because of non-expect variables? What kind of non-expect variables could be affected to a new project? 

The main subject of this article starts with the center competition of a business. It is going to study the reason of going on success or failure of a new project. And, it is going to research the effect of non-expect variables. It is going to make up the failure of non-expect variables to help reducing the amount of losing. And, it also gives some ideas of how to manage the risks when planned a new project.
