Kyoto Protocol and Copenhagen Accord have brought a consensus between nations to reduce their overall emission of greenhouse gases which makes the solar power a major source of power supply in the future. However, the impact of global financial crisis of 2008 has made the European and American countries to slash subsidies for solar energy eventually and diminished demands of solar systems. Ever since the China government launched the “Golden Sun” solar subsidy scheme in 2009, supply of solar systems keeps increasing along with the market price drop. These result long-term margin loss to the Solar Wafer manufacturers in Taiwan. In order to remain in business, manufactures must be able to improve production procedures and product quality continuously but also to control the cost of production effectively so they may have a chance to turn losses to profits.
The company chosen by this research is one of the leading manufacturers of Solar Wafer in Taiwan which provides its own products and customized OEM service. The company has implemented an ERP system which lacks integration and automation functions to support cost calculation involved with diverse OEM manufacturing models. Accounts have to spend a lot of time to organize and prepare billing data and upload the data to the system manually before getting the result of monthly cost. After getting the monthly cost, accounts have to organize the result manually in order to generate the data needed for cost analysis. The lack of a way to generate detailed and accurate cost data instantly and automatically does impact the efficiency of cost control to the company. To solve the problem, the company decided to implement a cost assist system to improve the efficiency of the billing process and data accuracy. This research is based on Leavitt’s Diamond Model (1965). Through case study, problems the company have encountered during implementation and strategies the company have adopted to solve problems were studied and analyzed to find out the critical success factors.
The result of this research verifies the effectiveness of the Diamond Model which shows existence of interference among the four components of the model: task, people, structure and technology. The result even shows chain reaction among the components. The result also shows a company must adjust resource distribution and structures of the four components with care during the implementation process for success. The critical success factors of the cost auxiliary system implementation include: 1. Rigorous project planning and execution capability; 2. Support and involvement from high rank management; 3.Professional technical skills of IT; 4. Cooperation between project members and key uses.
Key words: Diamond Model, Critical Success Factors, Cost Assist System
