To cope with individual production characteristics and respond to customers’ needs in the electronic industry, the information control and data collection solutions in the work sites will be varied by products.As a result, the management of on-site information system shall rapidly reflect just-in-time plant-wide data to improve production efficiency.With the diversified changes of customers' needs, the management of on-site information becomes more and more difficult. Therefore, a WIP system (work in process) enables to define the production data and collection solution of work processes based on customers' special requirements, and accommodate the system of roving inventory taking.The purpose of this study is to provide a framework of WIP system and explain how the system works to collect plant-wide data, which ensures to get just-in-time information from the product lines.
