當工廠生產進入了少量多樣的生產模式，若以大量生產的思維來管理工廠營運則會有此不太適合;單一大批量工單所能帶來的高產量、高效率及低成本的效益已慢慢消失，取而代之的是過往被視為不符合效益的少量多樣生產模式，卻因為個人化、客製化的意識成長，而慢慢影響工廠的運作。另外近年來各種開發板因為教育、商業應用及物聯網的需求而愈來愈多，而產生了各種易於開發與使用的開發板;進而使開發板的開發平台限制也逐漸降低，可串連的感測器及可控製的設備也不斷的在增加。
本研究主要將探討為配合工廠因生產模式的轉變，由大批量生產轉型為少量多樣的過程中，透過線場主管與作業人員訪談後，藉由程式軟體開發並結合樹莓派開發板(Raspberry Pi)的硬體運用，實際落實於精實生產的推動；預防人為錯誤的發生、目視管理的應用都將利用開發板的導入，進而使用較低的成本達到管理的目的。

As manufacturing shifted towards low-volume, high-diversity production, managing factories with mass-production-oriented concepts would be rather unfit. The high-volume, high-efficiency, and low production cost brought by economies of scale from large orders are slowly vanishing. Contrarily, low-volume production once considered non-efficient is on the rise, riding the surge of preference for personalization and customization, which is gradually affecting factory operation. Also, development board has come into abundance in volume and variety due to its demand in education, commercial application, and internet of things. Many developer-friendly and user-friendly development boards are made, thus lowering development platform restrictions and increasing the types of sensors and control equipment that can be attached to the development board.
This research will discuss the adaption of lean management for a factory in the progress of converting from mass-production to small-scale, diverse production. Through discussions made with factory managers and operators, house-developed software and development board (Raspberry Pi) hardware are employed. Human-error prevention and visual management will be introduced through development board application to achieve lower cost.
