| The expertise and capabilities at the Lehrstuhl für Wirtschaftsinformatik at Technische Universität München allows us to combine research results from the domain of IT Project Management and Software Engineering with industry
experience and practical findings in order to develop such a cost estimation method. A multi-step modeling methodology is used to identify and classify the different components of an RFID project (such as hardware, software and middleware) and calculate the cost contribution of each factor.
Characteristics of the Cost Estimation Method:The cost assessment method will guide managers and decision makers in a step-by-step fashion towards assessing the cost of each component in the RFID project. For example, RFID projects are often viewed as consisting of RFID tags and readers. However, a typical RFID project also requires investments in additional computing infrastructure such as database servers, web servers and different application servers. Therefore, the cost of hardware is not just made up of the price of the tags, tag readers and the servers, but also of evaluating the different available options for each of these hardware components and accounting for the time and effort spent in such an evaluation. Similarly, integration cost involves developing or buying integration modules of middleware components. In addition to the price of such components other cost factors, such as testing the components, and their maintenance, will contribute to the overall cost of the project. Further, there is also a need to assess the extent to which the new RFID system impacts existing applications.
Our cost assessment method will provide a tool (consisting of forms, checklists and spreadsheets) that can be systematically used to document the different cost factors and cost components within each factor which will calculate the overall cost of a RFID project. By doing so, this project will alleviate some of the existing complexity and uncertainty associated with RFID projects. |
