今日產品發展快速，成熟的工業製造技術導致產品生命週期的縮短，企業之間的競爭激烈；唯有快速完整的發展產品方能為企業帶來最大利益。目前產品開發發展的研究中，主要都以單方面的需求考量進行研究。然而在產品開發的構想中如果僅考量其中一方，其所研究結果會令人感到未盡完善，而所開發之產品也無法得知是否能夠真正滿足消費者及企業兩者之需求。
本研究藉由現有設計方法的整合發展出一系列輔助設計構想發展的系統步驟，來協助企業及設計師進行產品整合開發的策略規劃。主要可分為兩階段。第一階段以自行車置物包為例，利用聯合分析法來取得顧客對該產品的各項屬性、水準的偏好程度，並以此為依據產生滿足不同族群消費者需求的設計構想組合。第二階段透過名義團體技術法求得企業經營者的開發能力及其製造水準之相關性在進行設計方案構想時所考量的評估準則及其權重值；並且應用於聯合分析所求得的成份效用值，重新予以評價。最後運用詮釋結構模式(Interpretive structural model,ISM)進行設計特徵的分群。藉此找出不同族群間的相異及相同之設計特徵；同時達到市場區隔及模組化的目的，設計出更符合顧客需求的產品族(Product Family)。

在本案例結果中可發現企業經營者的開發考量與消費者需求是有所差異的，同時透過本研究所提出的流程架構可從中取得理想的折衷方案，產生能同時滿足消費者與企業經營者的設計構想提案。研究結果顯示本研究之架構對於自行車置物包產品之成效為：
1. 縮短設計構想發想時間。
2.有效及清楚得知顧客偏好，並進行設計構想的有效發展。
3.在取得顧客偏好的同時也能兼顧到企業的生產需求。
3.有效提供企業對於新產品市場的發展策略。

Today, the product develops rapidly. Mature industrial manufacturing technology lead to shortened product life cycle and the intense competition among enterprises. Only the rapidly and completely develop products can bring the maximum benefits for enterprises. In the current study of product development, the main research considerate unilateral needs. However, if the concept of product development only considerate the one party, the results wouldn’t be perfect. And it can’t know the development of products whether to really meet the needs of both consumer and enterprises demand.
In the study, by using the existing design methods to develop the assist design concept development systems to assist enterprises and designers plan strategy for product development. In the first phase, take bike trunk for an example and use joint analysis to standard the preference degree of the products attributes, level which were perceived by the customers. And take this as basis to result design concept portfolio to meet the needs of the different consumer groups.
In the second phase, through the Nominal Group Technique (NGT) to achieve the advantages and disadvantages of enterprises and relevance of the product capacity using criteria and the amount of weight values in the assessment of the design concept. Use the composition utility values obtained from conjoint analysis to re-evaluate. And in the final, use Interpretive Structural Model (ISM) to classify design features. In order to identify the different and the same design features between groups. In the same time, reach market segments and the purpose of modular design, and design the Product Family to fit in with customer demand.
In the results, this case confirms there are some differences in the consumer demand and the development of enterprises. And the through the process of this study can achieve a structure balance to meet the needs of consumers and enterprises operators design concept proposals at the same time. The results showed that the structure of this study contributes to bike trunk product are as follows:
1. To shorten the design concept time.
2. To knows effective and clear customer preferences, and develops design ideas effectively.
3. Besides to obtain customer preferences, it also takes into account the needs of enterprises.
4. To provide the new product market development strategy for enterprise effectively.
