Research on Collaborative Marketing Practice of the Computer Industry

Chiu, Pei-Chin 30 August 2011 (has links)
With the technology evolves over time, science and production process has been updated continuously. Manufacturers not only provide higher efficiency, but also offers products with better cost effective to customers. However, accompanied by the global economy and development of information technology, competitions among enterprises are stronger. It also challenges the relationship between suppliers and their customers. As the result, this situation can not fulfilled customer¡¦s demand. The increased of productivity and smooth market information exchange are the common scenario to price competition. Therefore, increase competitive advantages and relationship building have become two major topics to both suppliers and manufacturers. With progress of times, technology and produce, make constant renewal science and technology, producer not only offer good products of efficiency but also the intersection of cost and product of advantage to the customer even more in the past. The economic environment that but it is globalized to follow, and the development of information technology, let the competition between enterprises be fierce day by day. Also let the supplier challenged with the customer's cooperation relation more extremely too. The traditional business model of making the trade of the price with quantity in the past, it has been already unable to satisfy the customer. The improvement of productivity, the market information on the network is smooth, the price competition that causes is the normality, no matter to supplier or manufacturer, how improve competitiveness and strong compound, it makes relations to be important subject. The research via observe ¡Binterview ¡Band relevant literature, sort out and propose coordination with academy and trend of development of collaborative marketing. With the vertical cooperation relation between supplier and customer in the industry, and expand while organizing the functionality is combined, sell the products to the market of goal in cooperation so that together. The meaning supplier in coordination with marketing is not merely to sell products and service to the customer, another respect is sold with customer's common cooperative planning on the market too, and it is essential to offer and assist, sell to terminal consumer smoothly products, only the intersection of products and smooth the intersection of sale and customer in customer. Through analyze, sum up, offer supplier and famous the intersection of computer and co-operation that manufacturer succeed in on sale throughout the factor, the conclusion studied can be offered in the future of industrial circle to strengthening the relation with the customer's partner, and the reference of enterprise's competitive strategy. This research is based on observation, interview and worldwide studies, integrated with development of collaborative marketing. From the vertical cooperation of supplier and customers and extended to functionality integration within organization; thus to market product to the target segment. Collaborative marketing is not only selling products to, but also services as well as product planning and market positioning with customers. It also provides assistance to successfully sell to end users. Through analysis, this research has concluded the factors of successful marketing of suppliers and well known computer manufacturers and strengthens future relationship with customers and competition strategies in the industry. As the result of this research, the more effective the collaborative marketing is, the better the product positioned perceived by the end users. However, the researches done previously focused more on supply chain and value chain analysis. In the past, enterprises prioritized collaborative manufacture and design and invested heavily on ERP rather than focusing on collaborative marketing which is the most valuable stage in the process. To market product collaboratively is actually to increase value and differentiate itself from others. Collaborative marketing indeed increase company¡¦s performance and stronger relationship with customer. This research highlighted the meaning of collaborative marketing and looking forward to active participation and discussion from academy.

A study of corporation change - the Case Study of Acer Company

Tsai, Chung-han 23 June 2005 (has links)
Because of the constant innovation of IT technology , firms have to face not only end users but also fast-changing production design. It makes firms¡¦ operation extremely difficult .Someone which may be the champion today will be the worst another day .This is the conspicuous situation in IT industry. Confronted by the worst circumstance and limited to the internal sources, Acer corp. must do some changes to its original corporation activities that contain brand and manufacturing. If not , Acer corp. will have a serious problem caused by internal and external forces. Acer corp. declared its re-engineering plan that divided the corporation into three groups in 2000. The way Acer corp. using to change is based on the situation that industry value chain subdivide into lots of parts. Because of the enterprise internal resources restricted, Acer cannot maintain the complete value chain .It must make a decision between brand operating and OEM parts. When Acer decides to focus on brand operating as its enterprise core, it needs to differentiate the principle from organization and business strategy to go with new principle . In the part of organizational change, the report makes an eye on organizational life cycle theory and organization efficiency to find out why it needs three independent main groups. The main change of business strategy is on the supply chain and marketing channel management. Change of Supply chain aims that Acer, after outsourcing OEM parts , makes use of OEM firms which are good at production and global logistic activity , to reduce its stock and save the cost. Change of marketing channels is to comply with diverse channels in European market to make great growth. Hence, Acer prepares to copy the European experience to U.S. and China . Finally , the report proves Acer¡¦s process of organizational change with Lewin and Kotter¡¦s theories to make a conclusion .
